FXO Card takes long to release a call.

Hello,

Am experiencing a problem with a Callmanager Express that i recently deployed.The problem is after a call is made,the FXO take a while to terminate the call-it shows the call as being active for some time though the call has long been completed,this is the output of the 'show voice call status'

SST_VOICE_GATEWAY#show voice call status

CallID CID ccVdb Port DSP/Ch Called # Codec Dial-peers

0xD815 891 0x65ABB2AC 0/2/2 0/1:1 *8076910095 g711ulaw 0/8071

0xD817 991 0x65AAE1E4 0/1/0 0/1:2 *8052783000 g711ulaw 0/805

2 active calls found

SST_VOICE_GATEWAY#

SST_VOICE_GATEWAY#

Please keep in mind that all the calls above have long been completed.

Sometimes when a number of calls are made-the FXO cards 'hold' on to the call for sometime till the FXO cards are reset-this is sometimes done by rebooting the router for the FXO cards to be reset.

These are the timers set on the FXO cards:

voice-port 0/0/3

cptone GB

timeouts interdigit 4

timeouts call-disconnect 2

timeouts wait-release 2

connection plar opx 101

impedance complex2

The IOS that the router is using is:

c2801-adventerprisek9-mz.124-15.T3.bin

How can this problem be solved?

Any suggestions are welcome.

Re: FXO Card takes long to release a call.

Make sure you configure some form of supervisory disconnect. You can configure this under the voice port "supervisory disconnect ".
