We are using a Quintum gateway and a sysmaster billing platform. Our callshops are using Visiontek equipment which require a C tone from the quintum i.e. to tell when to commence charging.
Call progression is :-
call shop > pstn > quintum cms > tdm/voip > destination #
Do I have to check with the carrier about it i.e. if they can provide connect and disconnect tone when Tenor sends connect and disconnect indication signal to the carrier.
