Show 87 – A SIP of Voice

The Packet Pushers voice crew reassembles, this time for a discussion of SIP trunks. Erik Peterson, Amy Arnold and Tom Hollingsworth are the technical talent this week, while Ethan Banks hosts and tries to keep up with the conversation without going, “Huh?” too many times. Hey, we can’t all be voice engineers. 😉

SIP gets a pretty good look from us as we take on the following talking points:

  • What’s SIP stand for, and what’s it used for?
  • What are the common alternatives to SIP, and why is SIP preferred?
  • What sorts of widely recognized hardware/software uses SIP?
  • How does SIP work?
  • Implementing SIP trunking in the enterprise for PSTN access.
  • What should enterprises be considering when planning a transition to SIP?
  • What is a Session Border Controller?
  • What is SIP normalization, and when does it need to be used?
  • SIP applications in production networks.
  • SIP troubleshooting tools. (Packet captures, ladder diagrams, per call debugging, and common show & debug commands.)
  • How do I learn more about SIP? (Read Tom’s review of the CiscoPress title “SIP Trunking”.)

We hope you enjoy this show, and don’t forget all of the different ways that you can follow the Packet Pushers to keep up with the content generated by our community.
