hi guys i m new to voip and just started my cvoice, i have a confusion plz help me out
1) if i want to connect a pbx/keysystem with a CO switch over analog lines then wat type of interfaces will be used at both end ?? i m asking this coz in cvoice book its written that if u want to connect keysystem to CO switch thru analog trunk lines the signalling used will be winkstart and all does that mean that the cards will also be E&m trunk cards ??? am i right in this ??
2) wat are the possible ways of connecting pbx/keysystem with a CO switch ( i mean physical interfaces and the signalling )
plz tell me in a bit detail coz i m very much confused
thanks in advance
