I am trying one last time to get our Panasonic KXTD 816 to support DID with our ISDN2e lines. We have been paying BT for years to provide 10x DDI numbers on our 2 x ISDN lines (4 channels total) but when dialled they all just ring out the main exchange number on the Panasonic. The Panasonic has point-to-point set for all ISDN ports. BT swear that they have set the ISDN lines to match but I have a nasty suspicion that they are really set point-to-multipoint. When I plugged a basic ISDN terminal adapter into one of the ISDN NTE boxes I got a dial tone on an analogue handset and that I think means that the line is point-to-multipoint. Is there any way to confirm this on the Panasonic? Changing the Panasonic ISDN line settings to "multipoint" from "point" using the management handset and rebooting does not make any difference to the incoming call behaviour.

BT Line setting?

it the call is coming in, the lines are ok. BT normally are point to point you need to set the numbers in the ddi table (Prog 150) and tell it to ring what extension you want. prog (151/152)
the number maybe just the last 4 - 6 digits of the number, you can see this if you call in and then go to program 998( i think) and look at the co that it came in on

Thank you for the quick response. I will try your suggested solutions as soon as I can get back to the site where this Panasonic is located (today I hope). It is a two hour drive which is a pain when the only way of programming the switch is from a handset. We tried the Russian Programmator for remote programming but as others have found this is not reliable and we proved that it can screw up some settings, presumably because the database in a UK switch does not match the software's fields. We used to have the DOS programming utility but lost it when the Windows NT laptop on which it was installed died (carelss, I know). Panasonic now tell us that as the switch is obsolete we have to self-support which is not helpful.

OK, very many thanks for your post, I got it fixed. When I put the t/a onto the ISDN NTE it gave me a dial tone which convinced me that BT had set the line point-to-mulitipoint so I reported it as a fault and after about 2 hours the dialtone ceased, telling me that the line was now set point to point to match the Panasonic. I then revisited the DDI and with your clue about 998 to check the CO I was able to see that only the last 6 digits were significant. Unlike other systems we have configured, this needed just the last 6 digits in the DDI table and all was good. Many thanks for your help I do not think I would have cracked this without.
