Nortel Networks was the dominant enterprise PBX vendor in Saudi Arabia from the 1990s through the late 2000s. Banks, government ministries, hospitals, hotels, and Vision-2030-precursor giga-projects all relied on Nortel Meridian, CS1000, Norstar, and BCM platforms. When Nortel collapsed in 2009-2010 and Avaya acquired the enterprise solutions business, KSA customers were left supporting platforms whose original vendor no longer existed.
EIE supported Nortel installations across KSA through the Nortel-direct era, the Avaya-Nortel transition, and into 2026. Our Nortel-trained engineers learned these platforms when they were new. The institutional memory is real. We installed many of the Meridian 1, CS1000, Norstar, and BCM systems still operational in KSA today, and we are one of the few firms in the Kingdom that genuinely supports them in 2026.
This page is for IT and facilities directors managing a Nortel legacy platform — what we support, what we can repair, what parts we source, and the migration paths to current platforms.
Nortel platforms we support
Meridian 1 (also Option series) — the flagship enterprise PBX. EIE supports Meridian 1 with Option 11C (small enterprise), Option 51C (small to mid), Option 61C (mid-enterprise), and Option 81C (large enterprise — up to 16,000 users on a single deployment). Common KSA install patterns include banking Option 81C with Symposium contact center, hospitality Option 11C/61C with HSIM-equivalent integrations, and government Option 81C with secure-messaging modules.
Communication Server 1000 (CS1000) — Nortel’s IP-evolution flagship. EIE supports CS1000M (Meridian-style cabinet), CS1000S (server-based), and CS1000E (enterprise) across releases 4.0 through 7.6. CS1000 Release 7 is the most common in KSA in 2026 and the typical migration source.
Norstar (Compact ICS, Modular ICS, Norstar Plus) — small and mid-business key system family. Widely deployed across KSA branch offices, small clinics, dental practices, and small hospitality. EIE supports all Norstar generations from the original Compact ICS through Norstar Plus.
Business Communications Manager (BCM) — Nortel’s converged voice/data platform for small to mid-business. EIE supports BCM 50 (smallest), BCM 200, BCM 400, and BCM 450 (largest) across releases.
Communication Server 2100 (CS2100) — large enterprise carrier-grade platform deployed at some KSA Tier-1 customer sites; less common but supported.
CallPilot voicemail — Nortel’s integrated messaging platform. EIE supports CallPilot 100, 150, 201i, 600r, and 1005r generations as deployed alongside Meridian, CS1000, and BCM.
Symposium contact center — Nortel’s call center application running alongside Meridian and CS1000 in KSA bank and large-enterprise contact centers. EIE supports Symposium TPS (telephony), Symposium Web Center Portal, and the Nortel ACD overlay variants.
Meridian Companion — DECT wireless system common in Nortel-era hospitality and hospital deployments. EIE sources base stations and handsets from secondary-market suppliers.
Nortel phones and devices we support
M-series digital phones — the workhorse of Meridian and CS1000 desk-phone deployments: – M2008 (8-line basic) – M2616 (16-line standard) – M3902 (entry-level digital) – M3903 (mid-tier with display) – M3904 (advanced display + soft keys) – M3905 (executive flagship)
T-series Norstar phones — for Norstar deployments: – T7100 (basic) – T7208 (8-button) – T7316 (16-button) – T7316E (enhanced 16-button with display)
i-series IP phones — i2002, i2004, i2007, i2050 SoftPhone — IP migration to CS1000.
Meridian Mail handsets and Meridian Companion handsets — wireless DECT replacements through secondary-market sourcing.
EIE handles repair (where serviceable), replacement (sourcing from secondary market), and migration to current Mitel handsets when the underlying platform is migrated.
What support looks like for Nortel in 2026
The Nortel-as-vendor era ended in 2010. Avaya acquired the Nortel Enterprise Solutions business and continued some level of support through the 2010s, but most legacy Nortel platforms have been end-of-support since 2015-2018. EIE provides post-vendor support across all Nortel platforms:
Diagnostic engagements — Meridian 1 cabinet inspection, common control diagnostics, line card failure isolation, T1/E1 trunk troubleshooting, ISDN BRI/PRI diagnostics, ACD overlay debugging, voicemail (CallPilot) issue resolution, and configuration drift analysis.
Parts sourcing — Nortel-branded new parts ceased manufacture years ago. EIE sources from vetted secondary-market suppliers across line cards (analog, digital, T1/E1 trunk, BRI/PRI), common control packs, switch matrix cards, power supplies, signaling server hardware, and CallPilot processor cards. Internal parts inventory at EIE Jeddah covers common-failure components.
Configuration backup — periodic Backup utility runs to capture customer configurations to EIE-secured archive, supporting restore-to-known-good-state during major incidents.
CallPilot support — diagnostic, configuration tuning, mailbox management, and voicemail data preservation. CallPilot 5.x customers often the migration trigger because the underlying Windows server hardware fails.
Symposium contact center support — for Symposium TPS environments still running, EIE provides ongoing tuning, agent provisioning, ACD logic adjustments, and replacement planning to MiContact Center Enterprise.
Annual support contracts — flat-fee annual agreements covering scheduled visits, response SLA, on-site spares inventory, configuration backup, and incident response. Most viable economic path for KSA customers running Nortel in 2026.
Migration paths for Nortel customers
The dominant migration destination from Nortel legacy is Mitel — driven by EIE’s 25-year Mitel Gold Partnership, Mitel’s strong KSA channel maturity, and the fact that Mitel acquired some Nortel intellectual property assets through the bankruptcy estate, giving Mitel migration tools genuine engineering depth into Nortel data formats.
Nortel CS1000 → Mitel MX-ONE — large enterprise path. Extension dial plans port natively to MX-ONE numbering plan. CallPilot voicemail data migrates to MiCollab through supported export tools. Symposium contact center logic rebuilds on MiContact Center Enterprise. M-series and i-series phones replace with Mitel 6900 or 6800i SIP phones. Migration timeline 8-20 weeks for typical KSA enterprise estates.
Nortel Meridian 1 (Option series) → Mitel MX-ONE — similar to CS1000 with additional voicemail data path complexity for older CallPilot revisions. EIE has migrated Meridian 1 estates from Option 11C through Option 81C in KSA banking and government.
Nortel Norstar → Mitel MiVoice Business — small/mid-market path. Norstar dial plans, hunt groups, and time-of-day routing rebuilt on MiVoice Business. T-series phones replace with Mitel 6800i or 6900 series. Norstar voicemail (Flash, StarTalk) data migrates where data export remains accessible. Migration timeline 4-10 weeks for typical Norstar estates.
Nortel BCM → Mitel MiVoice Business — BCM converged platform migration. BCM voicemail data, ACD configurations, and IP/digital extension provisioning rebuilds on MiVoice Business. T-series phones replace.
Nortel CallPilot → Mitel MiCollab. Voicemail-only migrations are possible where customer wants to preserve mailbox histories without changing the underlying PBX. Less common but supported.
Nortel Symposium → Mitel MiContact Center Enterprise. Contact-center-only migrations, where customer has already replaced the PBX layer or runs Symposium overlay on a non-Nortel PBX. ACD scripts, agent configurations, skills-based routing, and queue logic rebuild on MiContact Center.
Migration mechanics across all Nortel-to-Mitel paths share core disciplines: extension number preservation (users dial the same internal numbers post-migration), voicemail mailbox continuity, hunt group recreation, ACD logic rebuild, parallel cutover with zero-downtime fallback, certified phone replacement, and dialect-Arabic user training.
Why EIE for Nortel legacy in KSA
Nortel-trained engineers — multiple EIE engineers learned Nortel during the Meridian / CS1000 / Norstar / BCM era directly, before vendor support ended. The training is institutional, not improvised.
KSA install base — EIE installed Meridian 1, CS1000, Norstar, and BCM systems across KSA banks, hospitals, government ministries, and hotels through the Nortel-direct era. The reference call list is long and the original installation documentation is in our archives.
Mitel migration certainty — EIE’s 25-year Mitel Gold Partnership combined with Nortel-platform engineering memory makes the Nortel-to-Mitel migration path the cleanest in the KSA market. We have done this dozens of times.
Three KSA offices — Jeddah HQ, Madinah, Riyadh. On-site engineer attendance across the western, northern, and central regions for diagnostic and parts replacement.
Symposium and CallPilot expertise — applications support that requires Nortel-platform institutional memory. Most KSA integrators do not have this. EIE does.
Frequently asked questions
Is Nortel CS1000 still supported by Avaya? Avaya provided some level of CS1000 support through the 2010s post-Nortel acquisition; formal support ended in stages and is not currently available for most CS1000 generations. Customer support today is delivered through experienced channel partners with Nortel-platform engineering memory. EIE is one of the longest-tenured Nortel-platform supporters in KSA.
Can I still buy spare parts for Meridian 1 Option 81C? New Nortel-branded parts are no longer manufactured. The secondary-market and remanufactured-parts ecosystem continues to supply line cards, common control, switch matrix, and power supplies. EIE maintains internal parts inventory for common Option 81C failure components and pre-positions spares at customer sites under support contracts.
My BCM 450 has been running 12 years. Should I migrate or extend? BCM 450 is in declared end-of-support across all releases. Parts are sourceable but increasingly expensive. Migration to Mitel MiVoice Business is the cleaner answer for most BCM 450 estates with a 12-24 month planning horizon. EIE will scope honestly in a 30-minute call.
What happens to Symposium contact center logic when we migrate to MiContact Center? Symposium ACD scripts, skill-based routing rules, queue configurations, agent skill profiles, and priority logic are extracted from Symposium and rebuilt on MiContact Center Enterprise. The rebuild is engineered, not automated — but the logic preservation is comprehensive when planned with sufficient discovery time. Symposium-to-MiContact-Center migrations typically take 6-10 weeks of contact-center-specific work alongside the larger PBX migration.
My CallPilot 5.0 is on aging hardware. What are my options? CallPilot 5.x runs on Windows server hardware that has reached end-of-life. Three options: (1) replace the underlying server with refurbished compatible hardware (extends runway 12-24 months); (2) migrate CallPilot to MiCollab as a voicemail-only migration; (3) full PBX + voicemail migration to Mitel. EIE recommends option (3) for most KSA customers in 2026 because the rest of the underlying Nortel platform is also approaching end-of-runway.
Will my Nortel M3905 phones work after migration to Mitel? M3905 is Nortel-platform proprietary and does not transfer to Mitel native operation. Migration includes phone replacement to Mitel 6900 series (6920, 6930, 6940, 6970) for executive and standard office use, or 6800i series for mid-tier and budget-sensitive deployments.
How long does a Nortel CS1000 to Mitel MX-ONE migration take? 8-20 weeks for typical KSA enterprise estates depending on size, voicemail data migration scope, contact-center migration scope, and number of sites. Multi-site banking estates with Symposium can extend to 24+ weeks. Migration runs parallel-cutover style — the legacy and new system co-exist during transition for zero-downtime fallback and emergency rollback capability.
Do you support Norstar in remote KSA branch offices? Yes. EIE supports Norstar across branch deployments — Compact ICS and Modular ICS most common. Many KSA retail and banking branch networks still operate on Norstar through 2026. Migration to Mitel MiVoice Business is feasible for branch-by-branch rollout when business case develops.
