Nortel Product Migration Matrix — Every Nortel Product and Modern Equivalents
Nortel made hundreds of products across enterprise communications, networking, and contact centre during its 100-year run. When the company ended in 2009, that catalogue split: Avaya took the enterprise communications line; the networking gear eventually moved to Extreme Networks; Genband acquired the carrier products; and the rest dispersed. Saudi enterprises still operate hundreds of Nortel products in production, and each one has a specific path forward in 2026.
This page is a comprehensive reference for every major Nortel product family in active KSA deployment. For each product, we describe what it was, who supports it now (if anyone), and what we recommend as a modern equivalent or migration target. If you’re running any of these and need to plan an upgrade, this is your starting point.
For deeper coverage of specific migration paths, see our blog posts: When to Upgrade CS1000, Norstar/BCM Migration, Meridian Replacement, CallPilot Migration, Symposium Migration, IP Phone Replacement, ERS / Baystack Replacement, Nortel Parts in Saudi Arabia.
Enterprise PBX systems
Nortel Meridian 1 (Options 11C, 51C, 61C, 81C, 81-Series)
Nortel’s flagship enterprise PBX family from the late 1980s through 2000s. The Option 11C handled mid-size deployments (up to 1,000 stations); Option 51C and 61C scaled larger; Option 81C and the 81-200/81-400/81-800 variants handled enterprise scale with multi-shelf configurations.
Current support status: Avaya inherited the line in 2009, continued limited support, and most variants are now in extended-support status with no roadmap for new features or hardware. Spare parts are increasingly scarce.
Recommended migration paths:
- Avaya Aura — natural successor with direct migration tooling. Best for enterprises wanting minimum change management.
- Cisco UCM or Webex Calling — for organisations going Cisco-anchored or hybrid Microsoft Teams Phone.
- Mitel MX-ONE — for hospitality and mid-large enterprise prioritising lower TCO and contact-centre depth.
Migration timeline: 6-12 months for typical enterprise deployment. See our detailed Meridian replacement guide.
Nortel CS1000 (CS1000B, CS1000E, CS1000M)
The IP-evolution of the Meridian platform. CS1000B was the smaller variant; CS1000E was full enterprise; CS1000M added integrated PRI/BRI for hybrid TDM/IP environments. CS1000 was the platform Nortel positioned as the future when the company ended in 2009.
Current support status: Avaya-supported under the Nortel-branded line. Extended support active, no new feature development. Hardware availability via refurbishment. Increasingly identified as audit risk for NCA/SAMA compliance reviews.
Recommended migration paths:
- Avaya Aura — most natural feature-parity target.
- Cisco UCM — for Cisco-anchored organisations.
- Mitel MX-ONE — for cost-effective enterprise migration with strong hospitality vertical.
See our CS1000 upgrade decision framework.
Nortel SL-100 / DMS-100 / DMS-250
Carrier-class switching platforms originally for telco operators but deployed by some large Saudi enterprises and government entities for very large in-house deployments. SL-100 was the enterprise variant of DMS-100.
Current support status: The carrier line was acquired by GENBAND (now Ribbon Communications). Limited continuing support; most enterprise deployments have already migrated.
Recommended migration paths:
- Cisco UCM at full enterprise scale — handles 50,000+ extension deployments.
- Avaya Aura at large-enterprise scale.
- Ribbon’s modern carrier products if continuing in carrier context.
Small business / mid-market PBX
Nortel Norstar (CICS, MICS, MICS-XC, MICS-MX)
The Compact ICS (CICS) handled up to 24 stations; Modular ICS (MICS) scaled to 32-128 stations; MICS-XC and MICS-MX added expansion capacity and IP-trunk capability. Norstar was the dominant SMB phone system in KSA from the late 1990s through the 2000s.
Current support status: No vendor support. Spare parts via refurbishment specialists only. Many deployments still running because the systems work.
Recommended migration paths:
- Mitel MiVoice Office 250 — natural Norstar successor for SMB/mid-market with similar feature set.
- Microsoft Teams Phone — best for organisations on Microsoft 365.
- 3CX — budget-friendly alternative.
- Hosted PBX (Avaya Cloud Office, RingCentral) — for cloud-only preference.
See our Norstar/BCM migration roadmap.
Nortel Business Communications Manager (BCM 50, BCM 200, BCM 400, BCM 450)
The BCM family was Nortel’s converged voice-data SMB platform. BCM 50 handled 5-90 users; BCM 200 handled 20-220 users; BCM 400 handled 50-220 users with expanded capacity; BCM 450 was the final-generation IP-native variant supporting up to 250 users.
Current support status: Avaya wound down BCM support; the last BCM product end-of-sale was 2014. No vendor support. Refurbished parts available.
Recommended migration paths:
- Mitel MiVoice Office 250 — strong successor with equivalent feature breadth.
- Microsoft Teams Phone — for Microsoft-anchored organisations.
- Avaya IP Office — for organisations wanting a continuing Avaya path.
- 3CX — budget-friendly cloud or on-premise alternative.
Voicemail and messaging systems
Nortel CallPilot 100 and CallPilot 150
The CallPilot 100 and 150 were Nortel’s small-business voicemail and auto-attendant systems, designed to integrate with Norstar (CICS and MICS) and earlier BCM platforms. CallPilot 100 supported up to 16 mailboxes with 8 hours of storage; CallPilot 150 scaled to 40 mailboxes with 100+ hours of storage. Both ran on dedicated hardware with proprietary configuration via Nortel’s Element Manager.
Current support status: No vendor support. Hardware reaching end-of-life with parts increasingly rare. CompactFlash storage cards in some variants are particularly susceptible to failure after 15+ years of operation.
Recommended migration paths:
- If migrating Norstar/BCM PBX simultaneously: the new PBX platform’s bundled voicemail typically handles the requirement. Mitel MiVoice Office 250 includes embedded voicemail; Microsoft Teams Phone includes Cloud Voicemail; 3CX includes built-in voicemail.
- If keeping the existing Norstar/BCM (deferring full PBX migration): third-party voicemail platforms with Norstar/BCM compatibility are limited. The pragmatic option is migrating PBX and voicemail together rather than replacing voicemail in isolation.
- Cloud voicemail-only retrofit: a hosted voicemail service can sometimes integrate via SIP, allowing voicemail-only modernisation without full PBX replacement. Best for organisations 12-24 months away from full PBX migration.
Migration considerations: greeting re-recording, mailbox provisioning on new platform, distribution-list rebuild, optional historical message archive for compliance retention.
Nortel CallPilot (Enterprise — 192i, 600r, 702t)
The enterprise CallPilot platform served Meridian and CS1000 deployments at scale. CallPilot 192i was rack-mounted for up to 1,500 mailboxes; 600r and 702t scaled into the thousands. CallPilot Desktop Messaging integrated voicemail with Outlook for a unified-messaging experience that was years ahead of its time.
Current support status: Avaya-supported under continuing extended support. End-of-life pressure increasing as hardware ages.
Recommended migration paths:
- Avaya Messaging — Nortel-natural target with direct migration tooling.
- Microsoft Cloud Voicemail / Exchange Online unified messaging — for Microsoft-anchored organisations.
- Cisco Unity Connection — for Cisco-anchored deployments.
- Mitel NuPoint — for organisations migrating to Mitel.
See our enterprise CallPilot migration guide.
Nortel Voice Mail (NVM) / FlashTalk / Norstar Flash
The earlier Norstar voicemail variants. NVM was rackmount; FlashTalk and Norstar Flash were embedded modules that fit into the Norstar chassis directly. Limited capacity (typically under 30 mailboxes) but extremely reliable.
Current support status: No vendor support. Refurbished modules available; storage media (compact flash, hard drives in earlier variants) is the failure point.
Recommended migration paths: Same as CallPilot 100/150 — typically migrated together with the Norstar PBX itself rather than in isolation.
Contact centre platforms
Nortel Symposium Call Center 6.0 / Contact Center 7.x
Nortel’s enterprise contact-centre platforms. Symposium 6.0 was the late-1990s standard; Contact Center 7.x added IP-native features in the early 2000s. Deployed across Saudi banking, telco, government, and large hospitality contact centres.
Current support status: Avaya-supported in extended-support status. Migration pressure increasing as the platform ages and Avaya’s roadmap focuses on Avaya Aura Contact Center.
Recommended migration paths:
- Avaya Aura Contact Center — Nortel-natural target.
- Cisco UCCE (enterprise) or UCCX (mid-market).
- Mitel MiContact Center — for hospitality and mid-market.
- Genesys Cloud CX — for cloud-first contact-centre transformation.
- Microsoft Dynamics 365 + Teams — for Microsoft-anchored organisations.
See our Symposium migration guide.
Nortel Contact Center Management System (CCMS)
The reporting and analytics layer that sat on top of Symposium and Contact Center. CCMS provided agent performance, queue analytics, custom reporting, and historical analysis.
Current support status: Tied to the contact-centre platform support cycle.
Recommended migration paths: Each modern contact-centre platform includes equivalent reporting (sometimes deeper). Plan to recreate any custom reports during migration. Workforce management integrations (NICE WFM, Aspect, Verint) typically continue across platforms.
IP phones and digital handsets
Nortel IP Phone 1100 Series (1110, 1120E, 1140E, 1150E, 1160E, 1165E)
The dominant Nortel enterprise IP phone family of the 2000s. The 1140E was the most-deployed mid-tier executive phone; the 1150E added expansion module support; the 1165E was the premium with colour display.
Current support status: Avaya continued the line under Avaya branding. Limited new sales; refurbished units available.
Recommended migration paths:
- Avaya J169 / J179 / J189 — natural successors in the Avaya ecosystem.
- Yealink T46S / T48S / T54W — broad SIP compatibility, lower cost.
- Cisco 8800 series — for Cisco UCM environments.
- Mitel 6900 series — for Mitel migrations.
- Poly Edge E series — premium audio quality.
See our IP Phone replacement guide.
Nortel IP Phone 2000 Series (2001, 2002, 2004, 2007)
Earlier generation than the 1100 series. Strong colour displays for their era; the 2004 was particularly common in executive deployments. The 2007 with built-in expansion module was popular for receptionist and call-handler roles.
Current support status: No new units. Refurbished available but quality varies; many displays have aged.
Recommended migration paths: Same as 1100 series. The 2000 series equivalents in modern lines: Yealink T46S/T48S, Cisco 8841/8851, Avaya J179, Mitel 6930.
Nortel IP Softphone 2050
The PC softphone for Nortel-equipped users. Worked with CS1000 and Meridian via SIP/UNIStim signalling.
Current support status: Avaya inherited and extended support, but the product is in maintenance mode.
Recommended migration paths: Modern softphone clients from Avaya (Avaya Workplace), Cisco (Webex), Mitel (MiCollab), or Microsoft (Teams). Each integrates with its respective PBX platform.
Nortel IP Phone 3905
Budget endpoint for spare-coverage roles, common areas, and elevators. Limited features but inexpensive.
Current support status: No new units. Modern budget alternatives: Yealink T31P, Avaya J139 entry, Cisco 7811.
Nortel M-Series Digital Phones (M2616, M3902, M3903, M3904, M3905)
The digital phone family for Meridian and CS1000 deployments. M2616 was the older generation; M3902/M3903/M3904/M3905 was the common modern line. M3904 with its colour display and 24-button capacity was particularly common in Saudi banking and trader floors.
Current support status: No new units. Refurbished available. Headsets typically need adapter cables for modern phones.
Recommended migration paths: Phone replacement happens with PBX migration. Modern digital phones aren’t a thing — the modern world is IP. Equivalents on modern PBX platforms: Avaya J179 for executive use, Mitel 6930/6940 for executive, Yealink T48S/T54W for mid-tier, Cisco 8851/8861 in Cisco environments.
Nortel T-Series Digital Phones (T7100, T7208, T7316, T7316E, T7406)
The digital phone family for Norstar and BCM deployments. T7316 was the workhorse business phone; T7316E added enhanced features; T7406 was a wireless variant.
Current support status: No new units. Refurbished common but ageing handsets show wear in displays and keypads.
Recommended migration paths: SMB PBX migration (see Norstar/BCM section above) replaces phones simultaneously. Modern equivalents: Yealink T46S/T48S, Mitel 6920/6930, Avaya J139/J169.
Nortel Audio Conference Unit (ACU)
The conference phone unit for Nortel meeting rooms.
Recommended modern equivalents: Poly Trio C60 (premium with native Teams certification), Yealink CP965, Cisco 8832 conference phone, Polycom IP6000 / IP7000.
Networking — Ethernet Routing Switches and Baystack
Nortel ERS 1600 / 2500 / 4500 / 5500
The ERS family was Nortel’s enterprise switching line. The 1600 and 2500 were entry-level; the 4500 (4524, 4548, 4550) was the dominant campus access switch; the 5500 series (5510, 5520, 5530) was higher-end with more advanced features.
Current support status: Avaya inherited the line; Extreme Networks took over in 2017. Some products continued; most are now in extended-support or end-of-life.
Recommended migration paths:
- Cisco Catalyst 9300 — enterprise-standard replacement.
- Aruba CX 6200 / 6300 — competitive pricing with strong Wi-Fi integration.
- Cisco Meraki MS series — cloud-managed simplicity.
- Fortinet FortiSwitch — for Fortinet-anchored security environments.
- Extreme Networks ERS continuity — if you want to stay in the Nortel-Avaya-Extreme lineage.
See our ERS / Baystack replacement guide.
Nortel ERS 8000 / 8300 / 8600 / 8800
Higher-end ERS variants for distribution and core switching in larger deployments. The 8600 was Nortel’s flagship high-availability core switch.
Current support status: End-of-life across the line.
Recommended migration paths:
- Cisco Catalyst 9500 — modern core/distribution.
- Aruba CX 8400 — competitive core switching.
- Cisco Nexus — for data-centre core.
Nortel Baystack 350 / 380 / 450 / 460 / 470 / 5000
The earlier Nortel SMB and edge switching line. The 350, 380, 450, and 460 were the common 1990s-2000s variants. The 5000 series was newer and more capable.
Current support status: End-of-life.
Recommended migration paths: Same as ERS — Cisco, Aruba, Meraki, or Fortinet depending on environment and budget.
Nortel Passport (Multiprotocol Routers)
The Nortel Passport line handled WAN routing for older enterprises. Variants included Passport 7400, 8000, and 15000.
Current support status: End-of-life.
Recommended migration paths:
- Cisco ASR / ISR routers for traditional WAN routing.
- Modern SD-WAN platforms (Cisco Viptela, Fortinet Secure SD-WAN, Versa, Aruba EdgeConnect, VMware VeloCloud) for organisations modernising WAN architecture.
Nortel Secure Router (1001, 1002, 1004, 4134, 8×4)
The Nortel Secure Router family for branch office and small-site WAN connectivity.
Current support status: End-of-life.
Recommended migration paths: SD-WAN platforms or modern firewall-routers from Cisco, Fortinet, Sophos, Palo Alto.
Nortel Centillion
Older ATM and frame-relay switching equipment. End-of-life decades ago but occasionally still encountered in legacy deployments.
Recommended migration paths: If still operating Centillion, the recommendation is full network re-architecture. The technology generation is two-plus generations behind modern.
Wireless
Nortel WLAN 2200 / 2300 Series Access Points
The Nortel wireless line was acquired through DeviceVM in the mid-2000s. Access points were positioned for enterprise Wi-Fi.
Current support status: End-of-life across the entire line.
Recommended migration paths:
- Aruba AP-505 / AP-635 (Wi-Fi 6E) — strong enterprise wireless.
- Cisco Catalyst 9100 series Wi-Fi 6E.
- Cisco Meraki MR series — cloud-managed.
- Ruckus / CommScope Wi-Fi 6E.
- Fortinet FortiAP — for Fortinet-anchored security.
Replacement is the only realistic path. Wi-Fi 6E and Wi-Fi 7 deliver dramatic capacity and density improvements that legacy 802.11n/ac equipment can’t approach.
Nortel WLAN Mobility 2350 / 2360 Controllers
The wireless controllers for the Nortel WLAN APs.
Recommended migration paths: Modern wireless deployments often use cloud-managed approaches (Aruba Central, Meraki Dashboard, Cisco DNA Center) that don’t require dedicated controllers — or controller appliances for more on-premise-anchored deployments.
Other Nortel products
Nortel Communication Server 2100
The CS2100 was a smaller-scale variant in the CS1000 family, designed for branch and mid-market deployments.
Recommended migration paths: Same as CS1000 — Avaya Aura, Cisco UCM, or Mitel.
Nortel Multimedia Communication Server (MCS) 5100
SIP-native enterprise communications platform Nortel positioned for service-provider deployments.
Recommended migration paths: Modern SIP-native platforms — Avaya Aura, Cisco UCM, or service-provider-specific platforms from Ribbon Communications or similar.
Nortel SCS 500
SIP Convergence Server for smaller deployments.
Recommended migration paths: Modern SIP-PBX platforms (3CX, Mitel MiVoice Office 250, Microsoft Teams Phone).
Nortel CallPilot Application Builder
The custom IVR and application development environment for CallPilot. Saudi enterprises with custom applications (banking IVR, healthcare appointment reminders, government service IVR) often have substantial CallPilot Application Builder code.
Recommended migration paths: Migration requires rebuilding applications on the new platform. Modern equivalents:
- Avaya Experience Portal — for organisations going Avaya.
- Cisco Customer Voice Portal (CVP) — for Cisco environments.
- Genesys for cloud-first IVR development.
- Custom development on modern platforms (Asterisk, FreeSWITCH) for technically advanced organisations.
Application rebuild is typically 30-50% of total migration cost for Application Builder-heavy deployments. Plan accordingly.
How to use this matrix
Identify every Nortel product in your inventory using the sections above. For each product, the section describes the typical migration target and links (where applicable) to a deeper guide. The pattern for most Saudi enterprises is:
- Inventory. Document every Nortel product, model, and quantity. Include the integration points (CRM, ERP, contact-centre, recording, fax, alarm).
- Sequence. Determine which products to migrate first based on age, reliability, and business criticality.
- Platform decision. Choose the dominant target platform (Avaya, Cisco, or Mitel) for the PBX migration. Voicemail, contact-centre, and IP phone decisions typically follow the PBX choice.
- Phased rollout. Migration in waves over 3-12 months for typical enterprise estates.
For an inventory and migration assessment specific to your environment, book a discovery conversation. We deliver a written product-by-product migration plan with phasing, cost, and timeline.
