T-1 TRK 136 errors

[telcomII]

I have a Nortel 1000M RLS 5.5 T1 locally connected to a dialogic card in a dictation server in our data center. I am getting intermittant channels going into lockout. The channels will go back into an idle state given time. Not sure exactly how long before they go back to idle. When I test dialing the access code inside the facility or outside I never have a channel go into lockout. From what I gather out of the NTP is this is a release failure. How can I determine which side is failing. My therory is that when the client hangs up the phone the t-1 channel is getting the signal to disconnect but the dialogic card is not getting this signal to release its side and effectively cause the t-1 channel to go into lockout. After a timeout period the dialogic card finally releases the channel and the T-1 channel goes back to idle. Can anyone shead some troubleshooting tips on this. programming info is below.

A lockout condition is caused because the far end, in your case a dictation server has not released

Thanks, I'll see what I can find out on the dictation end.
