Hi There, I must apologise for being well below the average level when it comes to SIP and VOIP, I have never got involved in it and we have 15 analogue lines in each of our two offices. I have recently purchased 2 Draytek 2920VN's as we moved onto FTTP at my office and FTTC at head office.

I really want to get my head around the SIP functionality with the 2920vn. FIrstly, can they only handle 2 phones? also, what phones? are we limited to what models we can get?

I really appreciate your help here guys.

Cheers,

RIch
