[SR-Users] Multiple calls uac_replace_from()

[Anca Vamanu]

Hi Alex,


If you create dialog before and use the implementation that relies on 
dialog variables [1], it is safe to call uac_replace_from() multiple 
times on the same message, or even the same initial message but looped. 
The module will detect that uac_replace_from() was called multiple times 
on the same dialog by searching after the dialog vars it has stored and 
it will work correctly.
This is the usage that we tested and is ok. With the old implementation 
based on RR param, I don't think it works right calling it multiple 
times on the same message.

Regards,
Anca
