PROBLEM WITH FORWARDING ALL - SIP TRUNK

[alicia.vega]

Hello,

I'm experiencing the following problem:

I have this scenario: PSTN - SIP GW - CUCM6.1 - SIP TRUNK - CUM8.6

Phone A (extension 33476761834) is registered on CUCM8.6, with external forwarding to the PSTN.

If someone from CUCM8.6 calls - it works.

If someone from CUCM6.1 or from PSTN calls - fast busy. Error in CUCM traces:

19:20:47.056 |//SIP/SIPTcp/wait_SdlSPISignal: Outgoing SIP TCP message to 145.245.235.201 on port 36615 index 3295

Any idea? Thanks a lot!

Alicia,

I have looked at your traces and here are my observations..

1. It looks as if you have enabled EO on the CUCM8.6 sip trunk, hence cucm tryies to allocate a MTP device for EO. Here we can see that MTP_4 was allocated

18:59:16.564 |MediaResourceManager::waiting_MrmAllocateMtpResourceRes - CI=62999932 deviceName=MTP_4 deviceCap=57 count=1|3,100,63,1.95460^145.245.235.201^*

2. While cucm was computitng the SDP needed to send EO, something goes wrong. It is not clear what went wrong but we can see CUCM de-allocating the selected MTP device..

18:59:16.753 |SIG-MediaManager-(17782) - eoCleanup - Deallocated MTP - resourceCI(62999932), MRM(3,1)|2,100,63,1.580390^145.245.235.232^*

3. CUCM then says that an invalid disconnect cause happened. It didnt tell us exactly what happened

Its a little difficult to tell whats going on here but here are my thoughts

1. It is possible CUCM is unable to do DO-EO over two sip trunks from different CUCM clusters

2. There may be a problem with the selected MTP device..

Suggestions...

1. Try and enable EO on the sip trunk on CUCM6.1 or

2. Try to disable EO on CUCM8.6 or

3. Remove MTP_4 from your MRG and see if another MTP device will work for DO-EO

Let m know if any of the suggestions work

The problem is because in the redirect header, the comma "," is not a valid parameter so in the alerting name I removed the comma after the surname (i.e. "Elodie, Mary" to "Elodie Mary" and now is working.

We will change the alerting name by the moment and I will also investigate if there is a parameter to just not divert this name because is not needed this info in forwarded calls.

Anyway the problem is solved
