Morning,

I am about to setup a very small phone system comprising a Siemens SX353 
ISDN phone + 4 paired DECT handsets connected to a single ISDN2e line.

The phone supports DDI/MSN call routing but there's no information about 
the format to use for setting this up, so can anyone enlighten me - for 
example, are MSNs entered as 4412345678990 or 12345678990 or just 5678990?

I guess trial and error will prevail if needed!?

Thanks

Start with just the last 6 digits...

DDI's are typically just the last six digits (certainly on director 
exchanges, despite their having seven), and very annoyingly BT don't tell 
you this at all.  So 678990.

For MSN's usually either the whole number arrives or the phone only switches 
on the last digit anyway, so try 012345678990.

In BT Highway (if you can still get it) the two analogue numbers were really 
MSN's stripped out by the NTE, although at the exchange end they were mapped 
as real numbers.

To save you some error, by default it's the last six digits, but this can 
be varied at the time of order.
