Hello,

have you changed the value for tm parameter 'reparse_invite':

Cheers,
Daniel

OK, but a problem is in partially re-parsing of CANCEL.

ru = modified ru;
tu = original tu;
fu = original fu.
In this case 481 received from GW.


INVITE  --> Kam   INVIRE -->
ru=a                       ru=c 
tu=a                       tu=c
fu=b                       fu=d         
<---100            <--- 100
<---180            <---180
CANCEL  -->       CANCEL -->
ru=a                ru=c
tu=a                tu=a
fu=b                fu=b
                <--481 Call/Transaction does not exist

Thank you,

Subject: Re: [SR-Users] How to rewrite "tu" in CANCEL message ?

Unless you rewrote the To-URI in the INVITE, you really should not try to
change a CANCEL. It needs to be almost a copy of the matching INVITE.

Hi,

probably the best way is to simply use the uac_replace_to-method from
the uac module:

http://www.kamailio.org/docs/modules/devel/modules/uac.html#id2494560
(tested with 3.3)

Kind regards,
Carsten

Hello all,





Is there any way to rewrite “tu” in CANCEL message in 3.2.1?



We use remove_hf / insert_hf   for INVITE’s “tu” modification before
t_relay.



It works fine, but it doesn’t work for CANCEL (INVITE re-parsing is
disabled).



Ths,
