SIP Trunking Triumphs and Torments

SIP Trunking Triumphs and Torments Setting aside some time in March to get your SIP trunking questions answered.

Setting aside some time in March to get your SIP trunking questions answered.

SIP trunking should be a commodity installation. Unfortunately this is not true for the majority of implementations. Year after year The SIP School has published its annual SIP Survey, which demonstrates that the same implementation problems have persisted for the last four years. The survey is analyzed in the blogs Different Year, Same Old SIP Trunk Provider Problems and Why SIP Problems Persist--and What to Do About Them.

BoF at Enterprise Connect

We are going to tackle these issues in the Enterprise Connect Birds of a Feather session "SIP Trunking Triumphs and Torments," scheduled for Wednesday, March 9 from 2:45 - 3 PM. The session description states:

"When the subject of SIP Trunking comes up, you're still as likely to hear complaints as you are compliments. The cost savings are there, but getting to those savings may still involve a frustrating process of troubleshooting deployments and translating terms that vary from provider to provider. This session will feature open discussion among the audience; you'll be encouraged to share your own stories of success and struggle, and offer advice to your peers about what works and what doesn't when you're trying to make SIP Trunks work for your enterprise. This session of networking with your peers will give you fresh ideas and new approaches to help solve your SIP Trunking problems and get ready to take the next steps."
Who's Responsible for Success with SIP?

There are five contributors to SIP trunk success:

  1. IP PBX vendors
  2. Edge device (SBC, NAT, firewall) vendors
  3. SIP trunk providers
  4. VARs
  5. Enterprise IT staff

This session is designed for participants to voice their experiences with SIP trunk implementations, both the problems and solutions. This session is not focused on the vendors, providers, or VARs; rather, it is focused on recommendations to reduce or eliminate the problems. The theme of this session is for the IT technologists to share their experiences.

Recurring Problems

The SIP Survey I mentioned earlier provides some insights to the problems and solutions involved in implementing SIP trunks. The common problems discovered by the survey that will be discussed during this session include:

  • Trunks dropping
  • One way audio
  • Poor voice quality
  • Codec mismatch
  • No audio
  • Trunk registration failure
  • Provider server failure
  • Firmware update
  • Calls blocked
  • No SIP licenses
  • Manual configuration errors

Many questions will be posed during the session for attendees to address, including:

  • Did you set up a trial before embarking on the implementation?
  • Did you acquire the SBC from the IP PBX vendor or a third party and why?
  • What problems surfaced during implementation?
  • How did you resolve the problem?
  • Who was most or least helpful (vendor, provider, VAR) in resolving problems?
  • Were most of the problems due to configuration errors?
  • Was the misconfiguration due to lack of knowledge, experience, training, or documentation?
  • Did you change vendors or providers?
  • If you had no problems, how do you account for this success?
  • What do you want the SIP trunk vendors and/or providers to add to their offerings?

I invite all to participate in this BoF session, whether you are considering, planning, implementing, or operating a SIP trunks installation. Although the SIP Survey is valuable, speaking to a contemporary brings home the issues and resolutions.
