[OpenSER-Users] Is it a bug? TM module is sending CANCEL requestregardlesswhat the script do with the From Header since 1.3.0

[Bai Shi]

I think avp can be choose to preserve in the whole transaction by modparam of TM module.
Try your luck at onreply_avp_mode (integer)
But I do think if openser could take this over, it'll be a nice thing. Anyway openser has to store a copy of sip msg, then why not store the manipulated version? Just a piece of mind =)

Hi,

> Actually it is different issue =P. You can manually change From in CANCEL in 1.2.2, however, in 1.3.0/1 even if you do manually modification, it won't work at all =).

I see. Well, problem is that you normally do quite some processing in
INVITE, loading stuff from DB and so on, which then can for example end
up in the From header. So is there a way to preserve AVPs so they're
available in the CANCEL as well? Or do I manually have to fetch all that
stuff again for the CANCEL?

Agreed.
