ADTRAN Discusses SIP Trunking and its Adoption to SIP-Based Services

By Stefanie Mosca, TMCnet Web Editor

Back in October at IT EXPO West in Los Angeles California, TMC’s (News - Alert) Patrick Barnard had the opportunity to sit down with Tim Saunders, vice president of product management for ADTRAN regarding the expansion of the company’s solutions into the SIP-based marketplace.   

ADTRAN, a global provider of networking and communications equipment has an innovative portfolio of more than 1,700 solutions for use in today’s telecommunications networks. Widely deployed by carriers, distributed enterprises and SMBs, ADTRAN (News - Alert) networking equipment solutions enable voice, data, video, and Internet communications across copper, fiber, and wireless network infrastructures.

“We are seeing a lot of growth specifically through our Tier 1 carrier customers. We sell solutions that are used to terminate a carrier SIP trunk service whether it’s a traditional PBX (News - Alert) or directly into an IP-PBX, or even part of a hosted solution,” Saunders told TMC.

According to Saunders, initially, that had been the domain of competitor carriers. “They were trying to sell a SIP trunk service. The Tier 1 carriers were using it mainly as a wind-back or if they were specifically asked for it.  Tier 1 carriers are now leading with that not only to SMBs but to large distributed enterprises,” he added.

Adtran’s products fit into two camps. They refer to them as IP business gateways, others know them as integrated access devices or IADs. Even though they are deployed inside the business and plugged into their walls, it still belongs to the carrier. What is does is terminate their SIP trunk service but then will feed a traditional trunk to the PBX, making it easy for the customer and not forcing them to change in their PBX, phone number, etc. In that space, we are seeing an increase in the amount of bandwidth needed.

“SIP is a standard, and anyone who is developing a component that implements SIP believes that they are doing it correctly and properly. But in fact there are nuances that are associated with things that may not be as mainstream as making a phone call such as a message indicator or showing that everybody has their own nuance,” Saunders said.
