I've just completed setting up the Brooktrout TR1000 4-port analog card on one of our servers and so far my reactions are postive.

There is an intel D/41JCT-LS in my other speech server. The Intel TIM seems to have a fancier UI but fewer configurable options. I like that the ports on the brooktrout card can be configured as bi-directional and can be enabled/disabled arbitrarily.

With the Intel TIM, one merely specifies how many outbound ports one would like. The TIM decides which ports will be allocated to outbound calling and allocates any remaining ports to inbound.

I'm looking forward to experimenting with this bi-directional port capability.
