SIP IP Phone to SCCP

[Jawad Ahmad]

Hello all, 

I'm facing a problem in our network, using SCCP and SIP IP phones. Problem is we can call from SCCP to SIP Phone and from Mobile to SIP phone working. But when we dial from SIP to SCCP or mobile its not working. How I can fix this issue.

SCCP Phones are 8941,8945. 

SIP phones are 3905.

please find attached file, Running config of CME and debugs.

Can you give "no digit collect kpml" command under voice register pool and check once.

I found a few problems with your configuration. Here's what I see:

1. Your SIP phone (Voice register pool) is set up to use G711ulaw, but all your dial-peers are G711alaw. Additionally, your transcoders are shutdown.

 shutdown

Please enable your transcoders or fix your codec, whichever you want to use. The transcoders would be my preferred route, that way you don't break anything with CUE.

no shut

Lastly, I'm afraid your debugs provided are incomplete, if you still have issues after this please post a full "Debug ccsip messages" as well as "debug voip ccapi inout".

Thanks,

I tried with change the codecs but it was not working.  Even  can not make a intrasite calls like 5846 to 7389. 

I will no shut the transcoder and share the result.
