Modifying the Contact field

2. Java version:

3. OS type and the version:

4. UA (phone), gateway or other hardware/software involved:

5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/ ... terns.html :

6. Your problem:I need to modify the Contact field in the Invite
request to operate with Callcentric. I know this issue was dicussed
in the past, but I don't believe there was a solution found.

You are probably referring to one of my posts. I didn't think it was worth the effort to try to interface with callcentric since Brekeke has integrated well with every other provider I ever heard of.

As it turns out, the problem is not the Contact Header, it's the multiple Via headers that are the issue.
I added &net.sip.via.multple=false to the deploy pattern for them and it solved the problem. The other issue that arose was that there default g.711 packet time is 40ms which Ondo doesn't support apparently. So I had to disable rtp relay. Does anyone know how to add a line to the sdp? I would like to add ptime:20
which would tell there server to use 20ms. packets.
