Hi everybody
I have a CCM 4.2(3)sr3a and many sites with IP telephony. Each site has its Gateway, a Cisco 2811 with FXO cards installed to make and receive calls. The IOS versión of the routers is c2800nm-advipservicesk9-mz.124-3h.bin.
Some of the FXO ports in several sites don't work properly, they block and when a call is received/made in those ports, it gets a silence. when it happends, the "show voice port summary" command shows an status "up down".
I have to restart the port and in the most difficult cases I have to restart the router to get the normal status "up dorm" at the ports if they are idle. The case doesn't seem to be in a particular router, it happens in different ports, in different routers and at different times.
I wonder if it is a bug in the IOS.
Could you please help me with this issue?
this is the relevant configuration of the ports:
voice class custom-cptone DISCONNECT
dualtone disconnect
frequency 421
cadence 200 200
voice-port 0/0/0
supervisory disconnect dualtone mid-call
supervisory custom-cptone DISCONNECT
timeouts call-disconnect 0
timeouts wait-release 1
timing hookflash-out 50
connection plar opx 29035
description CABECERA_PBX
station-id name ENTRADA_1
station-id number 2434928
caller-id enable
and the normal in/out dial-peers
Thanks to everybody

Can you try 12.4(3j) ?
That to align with the latest bug fixes.

Hi Paolo
I update the IOS in many of the routers of the network. it seems to be very stable, I think it solved the problem, but I used a newer IOS version: 12.4(19).
thanks for your advice.

Good, thanks for the appreciation and good luck!
Whn you want new features from the router w/ cme 4.2 I can suggest XW7 that is also stable now.
