[Asterisk-Users] Channelized T1, T100P problems

[Pat Boyle]

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.
