I am having a bit of a problem getting AMD to work on a new server. On
my regular office server it works like a charm. I am running Asterisk
1.4.13, Zaptel 1.4.5.1 on both machines. Both servers run CentOS 5 and
I am using a SIP trunk to send out calls (the same one on both servers).

Here is the output of a call on my office server:

When the call gets to AMD it just hangs there until you hangup. I
copied amd.conf to make sure I have the same parameters on both
machines. I simply cannot get AMD to do anything. The only way to get
out of AMD is to hang up the call. I do not understand why it works on
one server but not on the other.
