In theory Asterisk shouldn't have a lot of load. It's simply routing
calls (at 64kbit) and not converting them from one codec to another.
While there is no codec, there is echo canceling and there is servicing
the cards in a timely manner. So you need a pretty decent machine so it
can handle the timing, but it won't be slammed.
I noticed that one of the Adtran boxes can have an optional echo
cancellation module. When I asked a VAR about this they said it was a
special order item that they never kept in stock. According to the
Adtran web site the module is designed for "packetized voice
applications." It sounds at though Asterisk wouldn't have to put cycles
to echo cancellation with a module like this.
Unless you do VoIP on something with a larger delay than your LAN, there
isn't much to worry about.
I was also thinking that if I used more than one machine with TDMoE I
could potentially have better performance.
I still doen't understand why someone would do TDMoE when IAX provides
more flexibility.
