[cisco-voip] FXS ports stuck in WAIT_RELEASE state

[Andrew F. Wolfe]

Has anyone found an answer on this?  My third day on the job and I was given
this same issue for a customer and it is happening on 4 separate routers.
Since they are in production we cannot reload the router.  Has anyone....

1.  Found a way to clear the port without reloading the router?
2.  Found a fix or workaround?

TAC has not provided us with anything thus far.  The only thing they have
given us is to reload the router to clear the port and then after the reload
do the following debugs

debug vpm signal
debug voip ccapi inout
debug voip vtsp all

Then watch for the port to lock.  Let me know if anyone has anymore insight
on this.  Thaks.
