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?
