I have two Asterisk 1.4 boxes connected via IAX over a VPN tunnel on a<br>
10Mbit link. We never did any stress testing as it's a temporary<br>
arrangement, but we've never had any call quality issues or run up<br>
against concurrent ca, holl limitations. I'm mostly routing internal<br>
extensions over the trunk, and in the case of two floating users I<br>
have their extensions at each office ring when their DID is called.<br>
One server is an older Pentium 4 1.7 GHz with 1GB Ram, and the other<br>
is a Dual Xeon 2.33 GHz with 4GB Ram. As for codec, I'm disallowing<br>
all except ulaw and gsm, with ulaw the priority codec for hardphones<br>
(Polycom) and gsm the priority for softphones (X-Lite, Zoiper).<br>
<br>
I would expect the limitation you're going to run up against is not<br>
Asterisk, but the bandwidth between your two systems.<br>
