[OpenSIPS-Users] SUSPECT: Rewrite From Header In CANCEL forwarded packet

[Bogdan-Andrei Iancu]

Hi Marc,

use uac_replace_from() from UAC module to get changes persistent across 
the transaction:
    http://www.opensips.org/html/docs/modules/1.4.x/uac.html#id227417

Note the CANCEL is locally regenerated (even if received) - it is 
propagating hopbyhop.

Regards,
Bogdan
