CUC not answering the incoming calls

Hi dears,

 

we have a unified number of our institute and we use cisco unity to make the auto responsder of outside calls.

it was working fine and no issues , suddenly we got an issue of calling outside through SIP trunk with ITSP. and we fix it but the CUC is not responding to incoming calls from outside. 

 

after investigating starting from VG router ending with CUC, we found the following messages from CUC :

 

 

15:05:28.847 |26929,,,MiuSIPStack,10,Alert!!!, No line available on Server (Sub CUC )>>>10.5.155.63:5060 to handle this call.
15:05:28.847 |26929,,,-1,-1,Miu SIP Integration, All lines are busy on redirector (Sub CUC )>>> 10.5.155.63:5060. An incoming call will not be answered.
15:05:28.848 |26929,,,MiuSIPStack,10,TCP: destination address:port (Sub CUCM)>>> (10.5.155.61:5060)
15:05:28.848 |26929,,,MiuSIPStack,11,Outgoing Sip Message--> SIP/2.0 503 Service Unavailable

 

 

so it seems that the issue is located at CUC, what's the solution for this?

there is no changed happened 

AA means auto attended. 

So what i understood, calls to Auto attended is landing on the CUC call handler . ? is that correct ?

What about Voicemail ? Are you able to reach your mailboxes ?

the calls coming from VG router into cucm and then it translated to AA number.

when i called  AA number internally it open the session but without sound.

 

 

What about Voicemail ? Are you able to reach your mailboxes ?

Voicemail not configured to users yet, so no need to check that

Sub CUC )>>>10.5.155.63, What about your primary sever ?

Do you have trunk from CUCM to SUB CUC and ports configured ?



Response Signature


What about your primary sever ?

the calls is going through Secondary cucm 

 

Do you have trunk from CUCM to SUB CUC and ports configured ?

Yes and it's up

Is the SIP trunk between CM and CUC up? If you have configured it with SIP option ping you can see the status of it in CM trunk configuration page in the admin webUI.
