E1 Timeslots get stucked with S_R2_COLLECT R2_Q421_IDLE status

Hi all,

I am experiencing a problem with an E1 controller installed on a Cisco 2811 gateway. Since people make calls through the E1, some of the calls do not end correctly and the timeslots used by those calls get stucked with S_R2_COLLECT  R2_Q421_IDLE status. From the gateway  perspective those timeslots are unused and so free for new calls, but when it try to use them for new calls they are rejected. Does anyone know how could I solve this problem, please? Following are the controller configuration and the "show voice call summary" command output.

Thanks a lot!

Re: E1 Timeslots get stucked with S_R2_COLLECT R2_Q421_IDLE stat

What version of IOS is the gateway running? How quickly does one of the channels get stuck in that state?

Can you provide us with the entire running configuration as well as the output of the "show log" command?

Hi Felipe,

Following is the partial show version output. I have checked the show log output, but there was no logs related to this problem.

Can you also provide me with the "show run" output? If not the whole output, can you provide the dial-peer configuration?
