CUCM 7.1.5 PSTN incoming calls disconnect with normal call clear

Kleber Cruz

Hi, good afternoon.

We had a some disconnect calls incoming from PSTN with cause code 16, the calls dropped when going off-hook. The current version of CUCM is 7.1.5.33900-10, gateway H323 with E1 R2-digital.

 

We tried a check/unchecked MTP of gateway, check/unchecked Wait for Far End H.245 Terminal Capability Set, reset the gateway on the CUCM, configured the same DN at Ip Communicator but not solve.

 

In trace for RTMT appears the message: - ERROR: H245 signaling connection aborted!!!

 

Any suggest to fix the issue.

 

Attached sample trace for CUCM.

 

Best regards!

This bug doesn't say it affects CUCM 7.x, but perhaps this will lead you to more results.

Here is another case. https://community.cisco.com/t5/ip-telephony-and-phones/call-disconnect-errors/td-p/2491395

And they had some pretty good troubleshooting with this one.

Good luck.

Hi, I collected new traces and return the messages below:

We checked the SNR feature and not active in our environment.

 

Any suggested?

Kleber,

It certainly appears to be looking for a remote destination in those traces, which seems strange if you have not set up it. Maybe we can get this post bumped up to Anthony or Maren's attention and they may have an answer for you. This isn't something I have seen before and hopefully they have.
