We have cme in the Kansas City Area and every few weeks we get FXO ports that will not release the line its when a user hangs up. the issues clears for a couple weeks after i do a shut/no shut on the FXO interface. i'm trying to figure out how to stop this from happening.
I am running CME 10.0 on cisco 2901 running 15.4(2)T
Here is my config on all the voice ports
voice-port 0/X/X
trunk-group ALL_FXO
output attenuation -2
connection plar opx XXXX
description XXX-XXX-XXXX
caller-id enable
At this point i have not seen any pattern on which ports this happens to.

Hi,
I don't know how are the lines in US. But here in Spain, you must configure the "battery-reversal" command on every FXO port. The PSTN send to the customer a polarity change to notify the call end....
You can try it.... I hope to help you!!

apart from David (+5) suggestion, you can try to give below command under voice port.
timeouts wait-release 1

There are some debugs you can use to detect which type of disconnect supervision your TELCO supports, and configure accordingly.
