Does anyone here have any experience connecting to the Digium SIP trunk service? I've got a CIX40 with the most recent software as well as a current GIPU. I followed the instructions in the manual on SIP trunking as well as I could, but given that Digium isn't one of their listed providers, I'm guessing at some things.
Short story is that the trunks are working on a Grandstream gateway connected to an old Avaya system, but won't seem to work with the CIX.
Symptoms:
Calls into the DID go to busy signal. They should be routing to a PhDN.
For calls out, I dial the access code I created in Flexible Access Codes, hear dial tone, and dial an outside number. This service requires 10 digit dialing (no 1 or 0) but after 6 digits I get an "All Lines Busy" message on the display and hear a busy tone.
Clues? Thanks for reading
