No, you're missing the point. A call sentre will at least use ISDN for access to the real world, probaby a far larger pipe than that... 145mbit and up. You're using pots on your prone to ring the call centre, but they're certainly not using that technology to receive it!
The main user of cpu in this kind of system is the echo cancellation - which is why the bigger boards ( analogue digium tdm2400p / digital te412p for example ) support that on-board.
