Avaya Has Purchased Nortel

In 2010, Avaya completed the purchase of Nortel including the Norstar, Meridian, and BCM line of phone systems. There has been a planned end of sale of the venerable line of PBX's such as the BCM, Call Pilot, Compact ICS, and Modular ICS. Avaya has implemented a migration strategy to allow owners of Nortel Norstar Systems to leverage the cost of their desk phones for use with the Avaya IP Office PBX System, of which IP Office Techs has been selling and installing for 6 years now.

This has come to pass and as of June 2011 the previously mentioned product lines (with the exception of certain phone models) are not being sold as new. Please be aware that IP Office Techs will continue to service and program these PBX units and will replace them on request if parts are in stock. We anticiapate the parts will be available for many years to come on a refurbished basis. It will become increasingly difficult, however, to obtain licenses to increase feature counts, such as for example, the number of mailboxes available in a system.

Existing Nortel Phones Can Be Used in the New Avaya System

Avaya IP Office can now support legacy Nortel Norstar Digital and VoIP phones on the Avaya IP Office Platform Release 7. These phones include but are not limited to the popular T7316, T7316e, T7208, M7208, M7310, and M7324. Through the use of a new plug in module to the IP Office main chassis or stackable add-on modules such as the TCM-30, the capacity for the phones per system can be expanded to near 300. Furthermore these phones may be blended with the feature-rich set of of new and legacy Avaya phones. Theses include the new 9500 series which come with backlit screens, color display, touch screens, and bluetooth.

Rich IP Office Feature Set

Certain features of the Nortel line were not upgraded with modern business concepts in mind. The Avaya IP Office System is packed with new features and useability that our Nortel customers have asked for such as:

  • Forward to cell phone (with no loss of audio level or quality)
  • Caller displays on phone before you pick up the handset
  • No moving parts on main unit, system will not crash due to hard drive failure
  • Meet Me Conference Calls
  • Voicemail may be forwarded to your e-mail inbox or smart phone
  • SIP Trunking (allows connection to low cost phone lines over the Internet)
  • Road Warrior (Mobile Twinning) feature that allows you to pick up a call on either your desk phone or cell. If the call is picked up on the cell, you can seemlessly transfer the call to your desk phone with the push of a button
  • Telecommuter Mode uses your home PC and phone line as if you were in the office (no charges to your home phone)
  • Hi Capacity Digital Phone Lines (such as T1 and PRI)
  • DID Numbers (individual for each user)
  • Choice of carriers (such as Time Warner, PaeTec, BroadVox, GrandStream and more)
  • Faxing to and from the Desktop (with an add on module)
  • PC Based Operator Console for increased productivity
  • Multi-site Capability and Redundancy (for example, use one operator across sites and dial remote extensions without toll charges)
  • Internal and External Paging
  • Many Avaya phones have paperless labels so that buttons are always labelled correctly (labels are on the LCD screen)
  • Internal Music on Hold (no additional modules required)
  • User-friendly PC based graphical management tool
  • Real-time display of system activity, capacity, errors and alrerts
  • Easy backup of configuration to your PC
  • Integrated Ethernet port for PC based productivity tools and remote support
  • Call Recording (Optional Avaya Product)
