I've been having some problems getting a channelized T1 working with a T100P
card. Perhaps someone can help:
I have an Eschelon T1 coming into a Vina Integrator box. This box splits out
the T1 into an ethernet plug for bandwidth and a secondary T1 which I plug into
the T100P card. I've connected the two with a T1 crossover cable.
I get a green light on the t100p card and can make outbound calls. Inbound
calls are not working as well. Via the console, I can see them come in and
start the "s" extension, but then they hang up. Then the second
channel accepts a call, then I get a "all circuits busy" message on
the phone (from my cell as I call in to test). I'm testing from my cell
phone and never hear a ring or any of the asterisk welcome message (even though
it's showing in the console). It's as if the call appears to be answered
by the card, but actually never is.
Changing the "immediate=yes" to "no" changes behavior
somewhat. Then I get a message in the console that there is no extension
"6" defined, but if I define it, the problem doesn't go away.
I am using a channelized T1, not PRI. So we don't have b and d channels.
Just e&m signalling. Thanks for your help.
