Disconnect problem with CISCO 2610 Router


I have a big problem with my CISCO 2610 router.

It's configured to be able to carry out a VoIP network.

I can call from any land line (fixed phone) from Romania (I'm from Romania) at a local number, I receive a message like "Welcome to CISCO...", I enter an account number and then I call any number from US (for example).

Everything goes fine except one thing: after I close my connection, I mean I hang-up, the voice port doesn't disconnect for about 4 or 5 minutes. So even if there's no phone call, the line is busy for 5 minutes.

I've tried to set up the "Wait Release Time Out" parameter and "Call Disconnect Time Out", but there's still that problem.

What on earth can I do?

Can you help me, please?

Re: Disconnect problem with CISCO 2610 Router

This is a common problem with FXO ports, I still have outstanding case open with Cisco, have you looked at the trouble shooting tips for FXO gives you many different things to try on the voice port

also have you got the correct FXO card for your country?

good luck

Re: Disconnect problem with CISCO 2610 Router

I've read a lot of documents regarding FXO, FXS, voice ports, dial-peer, etc, but I still have the problem...

Are there FXO cards specific to a country?

Tanks for your previous answer.
