Ring Back Tone Detection with Asterisk / Freeswitch / OpenSIP
$250-750 USD
Paid on delivery
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.
