[OpenSIPS-Users] uac_replace_from causing issues with To header Version 2.1

[Bogdan-Andrei Iancu]

Hi Jonathan,

It will help if you could post the entire SIP flow for the call - to see 
the direction of the SIP requests (if TO and FROM are swapped) and the 
values for these headers (when sent out by UA's).
