Call Loop %CALL_CONTROL-6-CALL_LOOP

[golvic_23]

hello

Im having a problem with my Gateway that is showing following log message:

%CALL_CONTROL-6-CALL_LOOP: The incoming call has a global identifier already present in the list of currently handled calls. It is being refused.

Ando also shows another log message but i dont know if is cause of the same problem, this the another log message that is shown

%ISDN-6-CHAN_UNAVAILABLE: Interface Se0/1/0:15 Requested Channel 31 is not available

I have been looking for this log message but untill today i couldn't find the reason of this log.

I checked the dial-peers but for me looks fine, i can call to a diferent destination and also can receive calls, maybe some call are dropped but i dont

know from where, the log message says incoming call

im using a

Cisco 2851 router

IOS (C2800NM-SPSERVICESK9-M), Version 15.1(4)M4

I have one E1 to PSTN and another E1 as qsig connected to a PBX

I have seen this with overlapping dial peers, I would suggest removing all overlapping dial peers for testing and see if the issue goes away.

HTH,

I have some dial-peers with the same patterns but are pointing to a differente ip, i point these dial-peers to my CUCM Publisher and another dial-peers with the same patterns to my CUCM Subscriber, the dial-peers has different preferences.

I will do what you suggest and check if the problem disappears

hi Chris

i have identified the problem,  i did what you told me, i turned off the dial-peers with the same patterns, the log dissapeared,but i didn't know wich dial-peer was the one that presented problems. So i turned it on again.

I made some test to try to identify with wich calls appear the log message of the loop. Seeing the log message that says incoming calls, i  performed some calls to my DID numbers, with some DID's the call wasn't successfull so i looked in to this and i realized that the problem was that some of the DID numbers didn't exist. and also that i had 3 dial-peer defined with the same pattern one pointing to my CUCM Publisher, another to my CUCM Subscriber and the last one pointing to the Ip of my gateway.

I turned off the dial-peer pointing to the Ip gateway and the log has stoped appearing

Thanks for your Help

Regards!
