[asterisk-users] Asterisk sends the INTERNAL IP address of my equipments to my SIP friends?!?

[Nick Khamis]

You mean the SDP payload? You kind of need that....
c= is used for RTP transmission. o= always confuses
me so I will just say it's important at well.

You can put a proxy in the middle and do topology
hiding I guess however, that is beyond the scope of
this list?


Kind Regards,

Nick.
