Hi Charles, 

Did you ever get your USR 56k to connect via your SIP setup? 

I'm looking for info how to get my modems to connect togther. 

I have a cisco ata spa122 and I'm using asterisk and freepbx (front end). 
I have two extensions and they each can call and detect rings but never connect. 

I'm using pjsip (not legacy).

Someone has to have found the solution to this issue with modems over a VOIP system. 

.... The only place I want data loss is on my credit card!
