Hi guys,
just some useful info:
in pre 1.3.0, TM was not implementing hop-by-hop cancel (as generating
the requests), but it was doing just forward. In this case you had to
manually mangle the CANCEL request also, similar to INVITE one.
starting with 1.3.0, TM implements hop-by-hop cancel - it construct a
new CANCEL request instead of forwarding the received one. Here, the
FROM hdr changes (from INVITE) should be automatically reflected in the
newly generated CANCEL.....If not, it means two things:
- your CANCEL does not match any INVITE request
- it is a bug..
I will run some tests on trunk ....
Regards,
Bogdan

Hi Andreas,
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 think since TM module will take care of the uri rewriting, it should smart enough up
replace the From/To/Contact headers correct?

what the script do with the From Header since 1.3.0
Hi Bogdan,
you say that in 1.3 (opposite to 1.2), the
forwarded CANCELs preserve
the received FROM hdr instead of using the changed FROM, right?
I use 1.2.2 and I face the same issue. I do change the From in the
INVITE, but in CANCEL the unchanged header is sent out. Do I manually
have to replace From in the CANCEL as well, or should OpenSER
automatically take care of that?

I’m not sure if it is a bug. Currently our set up
need to do
masquerading on the From header for all invite requests. It used to
work okie when we process for the CANCEL request in the routing logic.
But after upgrading to openser 1.3.0, the TM module is sending CANCEL
out using local cached From info rather than the info processed by
uac_replace_from. May I know is this by design or it is a bug?
