FXO ports not releasing quickly

[pirinoe1920]

We have a 2801 router with CME 8.1 and CUE 3.2.3.  We receive calls on 3 analog lines into a 4 port FXO card.  When calls arrive they reach an Automated Attendant which routes the calls properly.  The issue we encounter is that the analog lines do not disconnect the calls quickly once the caller disconnects.  It takes approximately 140 seconds before the calls disconnect.  We have the following configuration on our FXO cards for each line.

voice port 0/0/0 to 0/0/2

voice-port 0/0/2
trunk-group main 1
timeouts call-disconnect 1
timeouts ringing infinity
timeouts wait-release 1
connection plar 1053
description PSTN XXX-XXX-XXXX
caller-id enable
 

Any ideas for what we are missing?

Thanks

Hi ,

Configure CP tone under voice ports according to your country...Like

voice-port 0/3/0

cptone NL

If that did not resolve disconnecting time then create a custom CPtone and apply it to voice ports , go through the below links.
