thanks dav, KAvin for your help and support.
i have a project that 3 sites each have Panasonic + Quadro E1 connected .
the easy way for follow me is to be done by the PBX.
i suggest if we use any sip server like Quadro 4x is this will help.
cause as i know and as i tried it will not gonna work.
i thought maybe by playing around with Quadro 4x in call routing table and creating ext samilier to what panasonic have it might work.

kavin i didn't mean anything man just thought that you understand that ext 100 is a quadro extension while it's Panasonic ext.

seams like no solution for this... Thanks alot dav, Kavin for your help.
