Nortel Launching New IP-PBX Software Upgrade Program: Page 2 of 3

"It's difficult for us to do budgeting if we don't know about a new [upgrade] until June and our budget is already done," said Karen Titus, president of INNUA and telecommunications engineering specialist at Swedish Health Services in Seattle.

Both Brampton, Ontario-based Nortel and INNUA collaborated over the past nine to 12 months to develop the program, Durham said.

Nortel now has to determine pricing for upgrades in advance, one of the more challenging aspects of the new program, Durham said.

The future releases, slated to come out at least every 12 months, will bolster the SIP (Session Initiation Protocol) capabilities of Nortel's platform. SIP is an emerging call control standard that Nortel plans to use to add collaborative applications such as instant messaging, file exchange and video calling to the Succession platform.

The new program will be available in the third quarter to customers using the current 3.0 Succession software release. Nortel did not publicly disclose pricing to protect partner margins.
