Background:
We are using an MD110, BC12 SP11.
There are some remomte analogue extensions in the PBX, and on these PSTN-lines we have activated a hotline to the R1 no in the PBX, to keep control over both incoming and outgoing traffic.

Q:
Would there be any advantages to change these PSTN-lines into ISDN2-lines, in terms of quality and/or higher realibility?
There can be a hotline on a ISDN-lines as well, right?
And how do you program a ISDN remote line in the MD110? Do I need any new licences, exept from the "Mobile" licences that are already installed?

Regards
/AL
