Has anyone successfully set up an Officeserv with Skyetel SIP trunks? I'm having a hell of a time. Takes ages to register and when the sip carrier options finally say its available, I can call out but incoming calls are failing. Their support says that the PBX is sending back a 600 Busy Everywere. I've tried setting the DID to be the 10 digit number as well as adding the 1 at the front. Neither was successful.

Any ideas?

Can you do a wireshark capture to see what's actually happening in the packets?
