Inbound calls from ITSP not disconnecting properly on IP Phones

[SamuelR87]

Hi Guys,

Looking for a little help if possible. I'm seeing an issue with inbound calls not disconnecting properly at the ip phone when the PSTN party disconnects the call, and it doesn't happen on outbound calls. I'm not sure if it's dial-peer or DTMF related, or something I've missed in the trunk config in cucm and I wondered if someone could point me in the right direction?

I've attached a sanitised version of the VG202 config if anyone is able to help me get to the bottom of it.

Many Thanks!

what type of connection from ITSP? Is it analogue connected to FXO?

Hey Nithin - it’s a SIP a connection.
