Hello!

In my architecture, SIP SUBSCRIBE messages can reach the Kamailio Presence server in several ways.

And I noticed that re-SUBSCRIBEs messages do not update the record_route field in the active_watchers table (MySQL), so subsequent SIP NOTIFY messages do not inherit it and have the routes set of the initial SIP SUBSCRIBE message.

Is there any way to change this behavior?
