IP500 with an ISDN30 currently in place and switching out for ISDN2 lines from BT.

for cost reasons they have decided to go with 2 ISDN2 lines

we have removed the t1 board and installed a 2 port BRI card in its place

the 2 port BRI card is seen in the config and viewed as lines 1 & 2

the BRI card is installed in slot 01 ( ports 09-10 on the IP500 )

set for ETSI and have tried default value 0 and 127

seeing the lines as in-service ( viewed within system status in that they no longer show as out-of-service )

pretty green with ISDN2 and IP Office

BT has passed off a NT connector

going to reach out to the provider and asked how they have the isdn2 lines setup to see if this will point me in the right direction ( more familiar with Avaya CM and BRI trunking )

when calling outbound I hear ringing and then a " waiting-for-line " on the screen appears -


cheers !

With BT ISDN2 the settings the card starts with are what's required, I have never needed to change them, ever. Only thing you may wish to change is to put the clock quality for the second circuit to fallback but that's it

Indeed, ISDN2 is so easy.
The only changes are prefix, and clock

The TIE value needs to be 0 when it is a group of ISDN2 when it is only one ISDN then it can be 127.
But as it is a pool then it is always 0

BAZINGA!

I'm not insane, my mother had me tested!

default the unit with the card in and re-do the config.

You can copy and paste 99% of it between two open copies of Manager (7 and above)
