PSTN phones is busy but CUCM does not relay the busy signal to the IP phone

Dear Experts,

I am experiencing this issue with CUCM 9.1. When a call is made from an IP phone to a PSTN number and if the PSTN number is busy, the call goes blank. The Ip phone goes to a long silence.

What I have learned from the the debugs is that when the far end phone is busy the service provider is sending a busy signal to the voice gateway (which is an H.232 GW). But some how the GW is not able to relay it to the CUCM.

Have any one faced this issue before. Please help with your valuable solutions.

Regards

Bejoy Thomas

PSTN phones is busy but CUCM does not relay the busy signal to t

We need to know what the PSTN is sending to the gateway when the call is busy. ccapi debug wont tell us this.What we see on the voip leg is cause code 17--which is user busy. But it could be that the PSTN played a prompt or something to say that the other party has hung up...So I need the isdn q931 logs

Alex,

While I agree that the above could possibly resolve the issue, I requested the debugs so we could have a clearer picture. We resolved a similar issue a few weeks ago in the thread beelow

Hi,

Here is the latest 'Debug ISDN q931'

Calling number 5004 (IP phone)

called number: 33512100  (Cell Phone)

Call action: call made from IP phone to mobile phone. when the mobile phone rang I press the cancel button on the mobile phone. The call ended on the mobile phone, but the IP phone still shows 'TO 33512100' and enters a long silence. I end the call on Ip phone by pressing the 'endcall' soft key.

=~=~=~=~=~=~=~=~=~=~=~= PuTTY log 2013.11.06 16:05:32 =~=~=~=~=~=~=~=~=~=~=~=

PSTN phones is busy but CUCM does not relay the busy signal to t

Hi Alex,

I tried the commands, but no luck

VIP Super Bronze

PSTN phones is busy but CUCM does not relay the busy signal to t

From the logs, it is clear why that commadn will not help because there is no PI in the disconnect.

The gateway received the proper disconect from the PSTN..

Nov  6 13:06:47.056: ISDN Se0/0/0:15 Q931: RX <- DISCONNECT pd = 8  callref = 0x974B

    Cause i = 0x8091 - User busy

*Nov  6 13:06:47.056: ISDN Se0/0/0:15 Q931: TX -> RELEASE pd = 8  callref = 0x174B

*Nov  6 13:06:47.056: //12060/004F49E50100/CCAPI/cc_api_call_disconnected:

   Cause Value=17, Interface=0x3D06F674, Call Id=12060.

+++++

We can also see that the call disconnect was sent immediately..

Nov  6 13:06:47.176: //12060/004F49E50100/CCAPI/cc_api_call_disconnect_done:

   Call Disconnect Event Sent

++++

So evrything looks okay on the gateway side. We will need to look at the CUCM logs to see whats going on and why CUCM is not telling the phone to hang up the call immediately. Can you please send us the detailed cucm traces.
