Details - If a UA initiate a session with the following From in the INVITE :


INVITE
From: "Daniel Grotti" <sip:051764814 at sip.mydomain.com>;tag=9B0D4664-1DCB


and afterwards set a different From inside 200 OK's ACK :


ACK
From: "Daniel Grotti" <sip:051764814 at 10.15.20.180>;tag=9B0D4664-1DCB


kamailio, with UAC module's parameter:


modparam("uac","restore_mode","auto")


can't restore the original From and sends out an ACK with a broken From like:


From: "Daniel Grotti" <sip:mydomain@%=&tt!-)>l29Vr.com>;tag=9B0D4664-1DCB


I solved for now setting:

modparam("uac","restore_mode","none")


But maybe could be interesting to solve the problem.
