[Serusers] Using Asterisk as mediagateway with or without rtpproxy

[Leon de Rooij]

Hi again :)

Got one more question about using a mediagateway. Right now I've got
everything configured that SER relays the call to our mediagateway
(asterisk) when necessary. The mediagateway is also on a public IP, but
only accepting UDP port 5060 connections from the SER proxy. (We use RP
(reverse path) filtering on our routers, so the IP address cannot be
spoofed). Come to think of it, I can additionally also filter on MAC
address since both machines are in the same LAN..
I read that a lot of people use an RTP proxy for forwarding the RTP
traffic to the gateway (which in turn is in a private net).

My question is: Is my setup less secure than using the RTP proxy ? If
so, why ?

Thanks !
