Hi, I have a system running for a while using sip trunking, but today the system stoped sending the outbound caller id, ans instead it sends the extension number to the sip provider, so the call can not complete, because the extension is not a DID for outbound. Why this happened by itself, and what can be wrong? i have the system down, and it only receives incomming calls. Everything was fine until today. Can someone tell me what can be wrong? Hi, I am attaching the log that the sip system is receiving from the elastix box, and instead of the 101 extension, it should be the 8 digits number in order to complete de call, I have been on this all day long, and dont find the reason why the DID is not being passed from the elastix system, [Jun 29 14:15:46] NOTICE: chan_sip.c:14422 handle_request_invite: Failed to authenticate user "101" <sip:email@example.com:19264>;tag=as2e26d322 as the 192.168.171.146 is the elastix machine and this cli message is on the CLI of the sip provider.
