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 versiÃ³n 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.
