Have you run into issues with it specifically?  Which version of DAHDI are you using?  If there are some issues that you have found I would like to know...

To be honest I haven't tried it with Asterisk version 1.4 or higher. I
only tried it with 1.2 and when the DAHDI was called "Zaptel". I have
been a little afraid to upgrade to 1.6 from 1.2 just in case there are
some incompatibilities in my config that'll bring down the phone system
here at the office for a while.

The issue that I had was that the even the calls were choppy. Not even
specifically just the MeetMe ones. But that was on VirtualBox. I am
using KVM now. I'm not sure if that matters.

What is your timer frequency set to in the kernel btw?
