Cisco CallManager Express – voicepulse

Updated 12-21-2008 by endrnet

 

Intro.

If you want to setup voicepulse (vp for short) service with a Cisco CallManager Express IOS router, this is the right place. There are no doubt tweaks that could improve what I’ve done, however it works for me.

Basics.

1) Voicepulse.com SIP trunk
2) Cisco CallManager Express
3) 3 Analog phones
4) 3 Cisco VOIP phones (7940, 7960, 7965)

Missing.

1) Business-style dialplan (9 for outside line, etc)
2) Voicemail backend to Asterisk with MWI integration

Caveats.

The configuration directives are voice related only. I was unable to make this work behind a NAT, Fa0/0 is a real Internet IP. If you’re interested in SIP trunks over NAT, this is probably not a good starting point. The main symptom I could not solve was the router receiving SIP messages with the outside IP embedded. Perhaps a SIP APG would work.

Additionally, I sanitized my configuration with a number of search/replace operations to protect the innocent. That search/replace might have broken something, but probably not. blah.blah.tld is a DDNS host. 10.20.30.4 is a tftp server, dns server, and ddns registration point. You can put these services on the router directly if you prefer.

Help.
