3CX call forward

3CX integration with ERPNext- call forwarding issues

 · 1 min read

When you are forwarding calls, either on inbound rules, or on extension , it passes the original caller-ID as sender-id. This make ISP's rejecting calls. Error message you see int the 3CX log normally is "Incomplete data" or something like that.


What you need to do is, change User part on SIP Trunk -> outbound parameters, as shown in the picture here.


ON SIP Trunk - > Outbound parameters .

From : User Part - change to 

"AUTH ID"Authenticaiton
