[asterisk-users] Sip and the media path

[Kevin Larsen]

You will want to look at the directmedia option. You will want all the 
phones on the same lan as the Asterisk server to be directmedia=yes and 
the ones on the wan to be directmedia=no. Then, internal calls will send 
the media between themselves without involving Asterisk, but ones outside 
on the wan will be forced to talk directly to the Asterisk server for 
everything. You might also want to look at the nonat option of 
directmedia.

We're running asterisk 1.8 in the DC on a public IP address.

Connecting to it are about 200 phones behind a LAN in a remote location.

Is there a way to reliably keep asterisk out of the media stream on 
internal calls inside that LAN? All phones are Polycom Soundpoint phones.

Asterisk would say in the media stream for any calls that traverse from 
LAN to WAN. However it would step out for LAN to LAN calls.

Thanks
David
