In the context of the development of our activity we seek a VOIP SIP TRUNK provider.
Our expected kind of traffic is typically Call Center, we're looking for a long-term parnership and high volumes.
We can generate from 100000 up to 500000 outgoing calls per day (between 10h00GMT+1 until 20h00GMT+1, except on sunday). Current destination is France – Mobile, all operators.
Very short calls only, so high bandwitdth is NOT required, NEITHER voice quality (almost no rtp traffic).
But good SIP signaling efficiency is required: INVITE -> RINGING -> HANGUP or CANCEL after typicall calling timeout between 8" - 10".
Of course, the number on concurrent channels must be tuned accordingly, but no so high thanks to the very short call duration.
Unless we agree to pay eventually for each miss call.
We also plan to duplicate this project in a few weeks, targetting Spain - Mobile, Portugal - Mobile, Brazil - Mobile.
