[asterisk-users] Control of RTP open ports

[Alejandro Cabrera Obed]

Dear all, I have an Asterisk 1.4.13 with SIP protocol and several voip
clients (Twinkle, X-Lite and SJPhone). Every call among voip clients
pass through the Asterisk server, so there isn't any voip packet
client-to-client.

Can Asterisk control the RTP open ports the voip clients use ??? Or the
RTP open ports depend on the voip clients ???

Special thanks

Alejandro
