Hello All,
I am looking for a procedure of how to send NOTIFY/SIPFrag messages on receiving REFER requests for call transfer scenarios. Basically I want to simulate following kind of flow:
Currently, on receiving REFER, asterisk sends only a single NOTIFY with Subscription-State: terminated;reason=noresource.
Is there any configuration on an asterisk that enables NOTIFY/SIPFrag as per RFC3515 Section 4.1 https://datatracker.ietf.org/doc/html/rfc3515#section-4.1?
Thanks
Rohit
