All the things you want are not too hard to do in asterisk, we have a
similar sort of set-up, except that
we happen (for historical reasons) to use a PRI isdn line.
The only thing on the list I see any problem with is forwarding - it
but if you mean forwarding an incoming PSTN call to a second PSTN
number, you will
find that you end up using 2 channels unless you pick an ISDN card
that can send the magic message to the providers switch to get it to
do the work.
- Mine doesn't (Hairpinning I think it is called). With only 4 lines
people consuming 2 for a call might be inconvenient.
My other bit of advice is _don't_ hurry the choice of phone.
Phones are a trade off - size/price/features etc. There is no single
'best' phone. My current favorite for an office SIP phone is the
but others will tell you different.
You _can't_ tell what a phone is like until you live with it for a
day or 2.
So set up your asterisk, make a shortlist of 3 phones and buy one of
Try them out, pick the one you like, then buy 9 more of them.
