Hi

We are trying to find out the possibility of developing a middleware (B) for our system.

We have

(A) a Voip Switch (Originator)

(C) A VoIP provider (Terminator)

(B) will be sitting in the center and 'listens' to each Ring Back Tone (RBT)

when a call is established and 'ringing'.

A--B--C

Originator -- Middleware -- Terminator

RTB frequecy will be based on standards according to Internation Telecommunication Union (ITU).

B will reject calls when RTB frequency are not met.
