Hello: I want to make a loop test from port 1 to port 2. Now, the pri show OK and UP. But the dialplan does not work. the call flow is : SIP A->Port 1->Port 2-> SIP B. it looks SIP A directly call to SIP B without going E1 ports. The attached file are inbound route file 、outbound route file and log file. Is there a problem with outbound route? what should i do? I hope you can help me,thank you.
