Hey all,
I have a Yeastar PBX U300 on one site and another Yeastar PBX U520 on another site and I've managed to connect both of them through SIP trunk but whenever I forward the incoming calls from the U300 to the U520 through the SIP trunk extension it shows on the phones that the trunk is the one dialing and not the number of the actual person who is making the call.
Anyone has ever encountered this problem or dealt with that?
If yes I would really appreciate anyone's support on the issue.
