One of our technology partners was in the market for a new VoIP provider. Of course they called us to see what kind of deals we could work. They were currently using a mainstream provider for Cisco Call Manager and Lecstar for their T1. Lecstar was going out of business, so they wanted to bundle the T1 and VoIP on the same bill. This company was using the Cisco 7960 phones in an MGCP configuration.

    We suggested they run our Asterisk (*) appliance in house... It took some good ole get down on the google'in, but we finally found the working configuration. Read on to see how we gotter dun...

    First we had to locate a compatible SIP image. VOIP-info.org helped out with this. We found the 6.3 SIP image online and downloaded it. Unfortunately, it did not come with all the files we needed. So back to Google, and we came up with the following blog. It got us through the basic configuration, but we were still unable to make calls on our in-house Asterisk deployment. The phone kept getting thrown to the default incoming catch-all context.

The trick was to change the line1_name parameter to the actual sip extension. Here is our working configuration of file SIP<MAC>.cnf:

<--SIP<MAC>.cnf-->

image_version: P0S3-06-3-00
line1_name : "106"
line1_authname : "106"
line1_password : "secret"
line1_displayname: "106"
line1_shortname: "x106"
line2_name : "107"
line2_authname : "107"
line2_password : "secret"

<--EOF-->

    After we made these necessary changes, everything worked like a charm! Thanks to the author of that blog for putting that helpful information up there!

Here is the rest of the working configuration as it sits on the TFTP server:
