Move to SIP Trunking Calls for New Skills

Susan Hall

Though telecom jobs overall continue to decline, a article argues that it would be a mistake for companies moving from TDM to SIP to move that responsibility to the IT team and lay off telecom workers.

Infonetics Research says the VoIP service market grew by 43 percent, reaching $49.8 billion in 2010 from $34.8 billion in 2008, reports FierceVOIP, with SIP trunking and hosted UC telephony the fastest-growing segments.


The story quotes Graham Francis, CIO of The SIP School training and certification program, saying:

All the telecom guys are going to have to understand how voice and data will mix on the same network. People with TDM backgrounds need knowledge about data switches, firewalls and proxy servers. They need to understand that on a data network, voice just becomes another application.

The telecom workers, the story says, bring skills to the equation, such as supporting quality of service for real-time applications-and quality of service is an issue in voice calls and teleconferencing. Francis says traditional telecom workers, though, need to learn more about traditional IT tools such as session border controllers and firewalls.


Jim Maloff, the principal consultant for Maloff NetResults, says one of the biggest adjustments is thinking of phone calls in terms of bandwidth instead of available lines-and voice calls don't get preference for bandwidth. He is quoted, saying:

The hardest thing for people who have been in telephony is now there's so much more they need to think about.

When I interviewed him, Hyoun Park, research analyst in telecom and unified communications for Aberdeen Group, advised telecom workers to focus on three areas: network-management skills, the challenges associated with cloud services and software-as-a-service, and social networking and social media monitoring.
