[Asterisk-Users] Debugging zaphfc + PBX integration

[Gavin Hamill]

Howdy - just got meself a cheapy Cologne chip card to play with in the hopes 
that it will prevail where a £1000 Eicon Diva Server failed...

I'm trying to run in NT mode and appear as a trunk to a PBX (it's an Inter-Tel 
Axxess unit).

If I hook a specific port on the BRI board of the PBX directly to a BT ISDN2e 
wallbox and dial 95000, I get a dialtone and can complete calls. Any time I 
connect to the Diva Server or the zaphfc card, the handset tells me 'TEST 
ISDN2 IS UNPLUGGED'...

I installed asterisk on a completely virgin box using the install.sh contained 
in the bristuff 0.2.0-RC7k tarball.

zaphfc: card 0 RX [ 0xfc 0xff 0x3 0xf 0x5a 0x1f 0x1 0xff ] 8 bytes

I'm told that the RX bytes are the PBX requesting a TEI from the provider 
(i.e. the * box) but I can't understand why no reply is being given.

This is precisely the same problem I had with the Eicon Diva Server card...

Is this likely to be as simple as needing the 100 ohm resistors, or can it be 
fixed with software?

Cheers
Gavin.
