Hi Bai Shi,
Andreas also confirmed to work properly (when not used from branch route), so it is not a bug, but maybe some cfg/scenario error.
Try placing the call (only the test one) and grab the full debug log from openser - post it somewhere and I will take a look.
Regards, Bogdan

Hi Andreas, I called without any branches.
Bogdan, I'd appreciate if you can spare sometime to look at this again. Rgds, Bai Shi

Or, to be more specific, I call it from a route which is called by a branch_route. Not sure if that matters.

Bogdan,
I just tested with 1.3.1, and there the From of the CANCEL is also NOT updated. A probably not so unimportant side-note is that I call uac_replace_from() from a branch_route.

Hi Bai Shi,
I just tested (to be sure no bugs are present) and in 1.3, the CANCELs are automatically updated (the FROM header), as expected.

Hi, Thomas, This will do in openser 1.2, however, in openser 1.3 it won't do any help. The CANCEL will be sent out regardless what you have done to the request, but follow the information in the original INVITE. I tested it and suffered a lot ;( Rgds, BS

Hi Thomas,
Yes, I'm doing it that way now (without that "append_branch()" though), but if you have an uuid-based setup where you fetch the uuid from the subscriber table during authentication of the INVITE and then with that uuid fetch dynamic data from the usr_preferences table to be used for "uac_rewrite_host()", then you have to do some work-arounds and hacks to get that data for the CANCEL as well, which could be quite a pain.
So yes, it would be really great if this could be done automatically *hint hint* :)

Applying uac_replace_from() to the CANCEL request should do the job, it sadly doesn't happen automagically :'-(
Try something like:
if(is_method("CANCEL") && uri =~ "^sip:...") { if(t_check_trans()) { rewritehostport("..."); uac_replace_from("..."); append_branch(); } if(!t_relay()) { sl_reply_error(); } }Cheers, Thomas Gelf

Hi,
I hit another problem with a Cisco PGW in combination with CANCEL, and I'm not sure which fault it is. If I do uac_replace_from in the INVITE, the From-Header is altered somehow and sent to the PGW. So if A calls B where B is a PGW, the From from A to OpenSER is for example sip:a@somedomain and from OpenSER to B it's sip:other-a@somedomain.
If the call is cancelled, the From-header isn't altered, so the From from A to OpenSER is sip:a@somedomain and from OpenSER to B it's sip:a@somedomain as well.
Now the PGW seems to ignore this CANCEL, and I guess it's because of the different From-usernames, since it works if I don't do any uac_replace_from.
RFC3261 says in §9.1: The Request-URI, Call-ID, To, the numeric part of CSeq, and From header fields in the CANCEL request MUST be identical to those in the request being cancelled, including tags.
So is it correct behavior of the PGW because the From header in the CANCEL is different from the From header in the INVITE? Should OpenSER alter the From in the CANCEL as well? Or should the PGW just check the From tags, but not the From URI?
