Voice port issue

Hi

Am having a problem with an E1 running from a PABX to a Cisco 2800 voice gateway.

when doing a sh voice por summ, I get the following, not all channels are going into the dormant state, the amount of channels increase/decrease at random, and starts disconnecting calls with a user busy tone:

PORT CH SIG-TYPE ADMIN OPER STATUS STATUS EC

Re: Voice port issue

which exact ios are you using ?

if you reload the router, does it behaves correctly for a while ?

Re: Voice port issue

Version 12.2(11)T2.

Have reloaded and then only 1 or 2 channels are in dormant state and then slowly increments, and then decrements again after a while. We have replaced the card in the router, replaced the cabling, and the card in the PABX, which has made no difference.

Re: Voice port issue

12.2T code is very old. I would put the most recent code that is 1) released for your platform or 2) fits on your flash and see if you get different results.

Re: Voice port issue

Thanks Nick, I'll have a look at a later version, log a change and upgrade. However in situations like this when down time is required, we have to provide a valid reason for upgrading, checked the bug toolkit and don't find anything specific to this problem. I'll give it a try and post results here soonest.

Thanks
