Hi Team, I configured a sip trunk fro sipgate.de. I can make incoming and outgoing calls. I can reach my extensions from PSTN by assigned DID, but I if I make call out, CID is always shown as a main trunk number. For DIDs I used format : 00492110001 For CIDs none of the tried formats doesn't work: not 00492110001, not 492110001, not 2110001, not 02110001 I thought it could be related to SIP TRUNK outbound parameters (P-Preferred Identity : User Part) but I'm not sure which one. Anybody who seen this issue before? may be on different SIP trunk providers?
