IP Telephony Case Study - NEW:
Legacy Nortel PBX Migrated to Cisco CallManager

A new document, "Case Study: Nortel 61C PBX to Cisco IP Telephony Migration," offers a detailed account of the steps taken at "Generic Services, Inc." to migrate from a Nortel Option 61C PBX to Cisco CallManager.

The migration goal was to build a nationwide frame relay network and consolidate all remote phones onto a centralized IP telephony system, which required four steps:

  1. Collecting key information from the Nortel PBX switch
  2. Adding and configuring the Primary Rate Interface (PRI) card
  3. Building the Route List index
  4. Validating the implementation

The case study describes each of the four steps in detail, providing a technical roadmap for businesses considering a similar migration.

To benefit from the lessons learned during this IP telephony migration, read "Case Study: Nortel 61C PBX to Cisco IP Telephony Migration," at:
