I connected cisco 3800 router with ericsson MD110 exchange using QSIG over E1 Pri. Calls are forwarding properly over ip network but few advance features are not being enabled like auto callback. In existing scenario,
User A-----MD110 PBX------------------MD110PBX-----User B
If a user A calls user B and user B is busy with someone else. User A will get busy tone, then user A will press digit 6 at that busy tone and put handset back to phone. When user B ends his call, a call is initiated automatically that rings bell of both phones A and B. Now when I implement voip and place routers in it, this feature no more working. My New scenario is below:
User A-----MD110 PBX ----RouterA---------------RouterB----MD110 PBX-----User B
I think, In voip topology when user A dials number, router A receives all digits and match dialpeer against it. When dialpeer matches, it forwards it to relevant router B and router B forward to pbx. And after that, router will not forward upcoming digits like 6 in this case and that's why this feature is not working. I think, I will become success to forward upcoming digits to other router after dialpeer match, this feature will start working over voip.
Waiting for immediate positive response.
