I have a 2801 gateway with 4 port FXS/DID card and about once a week, a voice port will get stuck in S_SETUP_REQ_PROC VTSP state and we need to go in and shut/no shutdown the port to clear it. Resetting the MGCP Endpoint in Call Manager also clears the issue.
We were originally on 12.4(11)T2 IOS and I found a bug with this issue, and it said it is fixed in 12.4(11)T4 so we upgraded to current 12.4(15)T which was 12.4(15)T6 at the time, but then we had a seperate FAX issue so used 12.4(11)T4 which has bug fix for this. After 1-2 weeks of being on that, we are having this problem again.
Just wondering if anyone has seen this with the FXS port getting stuck like this. We need to use MGCP as this port is shared with IP Phones and goes to a overhead bell so when the phone rings, the overhead bell rings at same time.
Below is capture of show voice-port trace from before we cleared the port of being stuck.
Call Manager version is 6.0.1-2000-4
