no - both ports are identical - even the BT engineer couldn't explain to me why there were 2

I assume you get two ports to allow you to plug in two ISDN phones. But ISDN phones are pretty rare in the UK.

Excellent,

Thanks Guys, any more ideas on the post above with the trunk kunundrum?

No idea why this isnt working, tested it with the PSTN line and it works fine. Just ISDN that seems to be the problem, thats why I though I'd maybe plugged something in wrong.

Thanks again

sorry to hear about your ISDN Trunk problems. I have a situation with a new install where I cannot make or receive a single call via the ISDN.
I too have 10 DDIs and I am trying to connect to 2 x ISDN2e boxes using ISDN-TE in IPPBX. Can you please let me know what your settings for ISDN Trunk, and other ISDN setting are in the 2820 IPPBX.

Many thanks SPP

That must be your P-P or P-MP settings - as per the second post in this thread.

No it can't be the Point to Point or Point to Multipoint settings as they can only be set to one or the other and I have tried both.

When attempting to make a call via ISDN the CallDetailsRecord shows that the call was a success for 6 seconds.
