[Users] Can't replace duplicate c= lines in SDP

[Ovidiu Sas]

Hello Jerome,

Check the following link:
http://www.openser.org/docs/modules/1.1.x/nathelper.html#AEN275

c - flags to change the session-level SDP connection (c=) IP if
media-description also includes connection information.



Hope this helps,
Ovidiu Sas
