1760, FXS port (MGCP) and Valcom V-9970, V-9924C

| Having issue with client where the Valcom paging stops
working periodically and they need reboot router or
bounce MGCP to clear things up.
The voice-port is default settings, and IOS is
12.4(3). They upgraded from 12.3(8)T3 and had same
problem with that also.
voice-port 0/1
timing hookflash-out 50
Not realy familiar with the Valcom stuff, but seen
previous discussions on valcom on the list. Any
tricks/gotchas with these model valcoms connecting to
FXS ports on voice gateways?

| That should be pretty much a no-brainer, so something else is going
on. By any chance, are you using another port on the FXS card? And if
so, does that port experience any of the same issues? I'm just trying
to rule out a hardware issue with the card. The only other thing that
I can think of is that the disconnect supervision gets lost and the
Valcom remains off-hook and locks up the port.. There is a fall-back
from the loop current drop method, which is "maximum page length" If
that is not enabled, you could try that to make sure that after, lets
say, 32 seconds or so the page drops the port no matter what.
One other thing to check, does doing a "shut / no shut" on the voice
port clear anything up? Like you mentioned, the reseting the MGCP
process fixes it too. Maybe there is an issue on the MGCP side locking
up the port. What state is it in when it locks up (IDLE?, IN USE?)
Anyway, hope this helps..

| I haven't seen the actual issue myself yet, live.
Waiting for them to report the next time it happens
and hopefully let me know so I can jump in there and
see. I asked they do a bunch of captures of show voice
commands, etc and some debugs to syslog server.
Asked they try a shut/no shut of port before trying
the no mgcp/mgcp trick and see if it clears it up.
