I've been trying
lots of configurations now. And the problem that I can't solve is
this:
I have a Digium
T205P card. I have connected one of the connections to our internal PBX (NEC
2000 IPS). The Asterisk is configured as pri_cpe, and the NEC is configured to
be the network side of the connection. Both ends are using b-channels 1-15 and
17-31, the d-channel is on 16.
When I start
everything, the link is ok on both ends, and it says that the D-channel is up
(on both ends).
Now, when I try to
dial from our internal PBX to the Asterisk, the call connects ok, but there is
no sound. But when I dial from the Asterisk to our NEC PBX everything works just
fine, and the sound is working perfectly.
One more strange
thing is that when I dial from the NEC to Asterisk, every time a new B-channel
is connecting the call (which I guess is normal). But it NEVER uses channel 31,
it skips from 30 to 1. But then it seems to try to connect the call on channel
16, which is the D-channel(!), and that of course fails. Both ends seem to be
setup correctly, and since the D-channel is initialized correctly, both ends
must be using the correct channel for this, but still Asterisk tries to connect
the incomming call B-channel on channel 1-30, instead of
1-15,17-31.
Could this be
caused by something in the Q.SIG protocol?
I have used the
NEC PBX with other PBX's, using Q.SIG. And everything has been working just
fine.
I've tried to look
at the PRI debug output, but not much help there... What information is needed
from me to get any help with this?
Best
