Is it a REFER sent in a dialog created with an INVITE?

Add the following in the [Configuration]->[Advanced] page once, and restart the SIP Server.

Code: Select all

&net.sip.outside.dialog.pattern = ^REFER|^NOTIFY

Now you can catch REFER with DialPlan even if it is sent in existing dialog.
Let you write DialPlan rule to catch REFER and modify it as you want.

Now I have the same problem but this solution does not work. Do I need to do anything else?
