[*] Local Digium Reseller

[LES.NET (1996) INC.]

Not really.

Simple reducing the number of interrupts by a factor of 10 would reduce
the load quite a bit.

The interrupts are used to pull the data off the T1 stream and provide it
to asterisk.

The sangoma cards pull it off more efficiently, and just provide it to
asterisk.

Not going to pretend to understand or be able to effectively describe
exactly how..  But anyone who's played with digum and sangoma cards says
hands down, the sangoma are better and place less load on the system.

Theres numerous articles on the interweeeb about performance tests people
have done too.
