That's really only about 1.5 B channels' worth >of throughput. Following the conversation, I take it an external ISDN TA is being used. If so, install a serial port with a faster UART. I believe it's 16650 or 16750 that's cabable of over 400k/s. I would suggest a vendor, but I honestly don't remember where my boss got his. (datacom comes to mind, but don't quote me on it :) This is assuming of course that FreeBSD won't have a problem with faster serial cards.
