We have two Asterisk servers. One is a live server supporting our
customers, and the other is a backup server that’s being upgraded and
pressed into service. Both servers have a Digium TE405P T1 card in them,
and in order to test the T1 service on the backup server, I’ve created a
T1 crossover cable (as per
http://www.voip-info.org/wiki/view/crossover+T1+cable) that goes from port
4 on the live server to port 1 on the backup server. Both TE405P’s have
been configured, and I get a green light on port 4 on the live server and
port 1 on the backup server.

The problem I have is trying to route calls through this T1 connection. To
the best of my knowledge, this configuration on the live server should
work:

In /etc/asterisk/chan_dahdi.conf:

group=4
context=local
switchtype = national
signalling = pri_cpe
channel => 73-95
context = default
group = 63

In /etc/asterisk/extensions.conf:

exten => _*88,1,Dial(DAHDI/g4/123456789)

However, in the Asterisk console, I get this error on the live server:
