Hi, we have a new sip trunk on the ISDX, its using Auth ID / password , trunk ID number and the Service providers SBC IP address . it is registered correctly.
Having problems trying to call out from a PBX extension via sip. the SP is saying the "contact" header needs amending as they are seeing the internal extension@IPaddress and need this to be the trunk group identity number , how do we amend this particular header please?
the From and To fields appear ok, the SP hasnt commented on these. only the Contact header.
