Hello,

You need to add the command under the voice-port 

bearer-cap speech or 3100 

Can you also share the debug isdn q931 output for failed call.

Can you confirm you not facing the same issue when normal IP phone calls out.

Please share the log for the same as well.

Could you share the sh run for the voice router.

Also can you confirm that video device is in same device pool as your normal IP phones ?

It could be codec mismatch issue.

Hello Rajkumar,

Attached normal calls debug isdn q931 and debug voip ccapi inout logs.

Calling Number :422

called Number : 30255290

and also attached the show run for the voice gateway.

Please note i have tried with same device pool and Location like working phones. still same result. i can see while dialing the number its taking with number@domain.

Please advise.

Hi,

Can you put the codec g729r8 on your existing voice class codec and assign to your voip dial-peer pointing to your CUCM (not just G711ulaw).

Also configure the transcoding resources on router and register with CUCM.

I feel it is somewhat related to DSP.

Raaj.

Hello Raaj,

Its works fine after done the above workaround.

Hi Ashiq,

Glad to hear its working.

could you share the output  for the command "show voice call status" from the gateway when the call is active from DX80

Also did you configure the transcoder or just modifying the voice class codec.

Please rate it answered if it resolves the issue.

Raaj.

Hello Raj,

i will share the voice call status output asap.

Yes i have configured the trans coder in the cucm and pointed to device pool.

Thanks for your help.

Ashiq.
