[cisco-voip] Voice Gateway issue

[Wes Sisk]

what protocol does the gateway use to communicate to callmanager?  
mgcp or h323?

what do you mean by 'reset the port'?

if mgcp need to make sure the gateway and port are still registered  
to CallManager. look at mgcp endpoint in ccmadmin pages and look at  
'show mgcp' on the gateway

if h323 need to see state of port like 'show voice trace

Hi Everybody,

We have a problem with a Cisco 1760 voice gateway that I hope someone  
can
help us with. We are running CCM 4.02 sr2b. The gateway in question  
is in
one of our smaller buildings. The router IOS version is 12.2(14.5)T. The
router has 2 FXO ports and 2 VWIC FXS ports. We have a Valcom overhead
paging unit connected to one of the FXS ports. Here's the problem:

Approximately every two weeks, sometimes more often, when they  
attempt to
make their closing announcement, the paging unit doesn't function -  
either
rings but never connects or gives a fast busy when they dial the  
extension.
Each time this happens, I reset the port and it starts working. This  
problem
is totally intermittent and therefore can't be reproduced. The unit  
works
just fine most of the time. We've monitored the gateway, reviewed  
logs, etc
after the failures, but can't find anything wrong there. We had someone
check the Valcom unit dipswitch settings and the jumper that controls  
the
timeout was not set to default. That was corrected, but the problem has
occurred twice since. We have two or three other Valcom units set up the
same way and they function without failures.

Does anyone have suggestions about how to track this one down? Any help
would be appreciated.

Thanks,

Faye Day
