[cisco-voip] FXS ports stuck in WAIT_RELEASE state

[Kevin Hoffer]

Funny you say this. I have a VocalData (Teklec) System and I am having
the same issue. TAC pointed to Vocaldata, and Vocaldata is telling me
it's a Cisco Bug but they are putting in a workaround.

Subject: [cisco-voip] FXS ports stuck in WAIT_RELEASE state

 

>From time to time I have customers who have problems with FXS ports
'locking up'.  In most cases when this happens the port will be stuck in
the S_WAIT_RELEASE state like so.

2/0/2         None       -  S_WAIT_RELEASE        FXSLS_ONHOOK      

I've not found any way to clear this except reloading the router.  I'm
wondering if anyone can give me some insight as to why this happens and
if there's a way to clear the port when it does. 

In this particular case, the connected device is a fax machine.  Is it
possible that the fax machine is causing some voltage on the line that
is seizing the port? If so, can anyone recommend a surge protector to
protect against this?      

This particular customer is running a 2821 with a HD-NM and 12.4(XC)4
but I've had the problem with VIC2-4FXS/DID cards as well. 

Thanks
