Call does not hang up on intercom when far end disconnects the call

[bholashrestha]

Hi Guys,

I am hoping someone can shed some lights on an issue I am experiencing with VG202 port configuration.

We have an intercom system which dials a pre programmed number (Cisco IP phone). The intercom Exchange line interface module is plugged into a VG202 port.
Standard FXS SCCP port configuration. When a call is made from the intercom the phone rings and media established all ok. But once the call is hung up on the remote end (cisco IP phone),
the intercom freezes and does not hang up for approximately 2 minutes. Just wondering if anyone has come accross with this type of issue and if there is anyway to make it work.
Any feed back will be much appreciated.

Below are the voice port and dial-peer configuration applied.

Usually this is what you'd need to have on the dial peer.
