Hi

I am a Fusion customer and I terminate my VFX line at Trixbox v2.6. From the perspective of the VFX service, is the call considered "delivered" as soon as it has been passed to Trixbox or does VFX still enable the functions available for unanswered calls in these cases? It seems to me that as soon as Trixbox has accepted the call and engaged one of its Inbound Routes, the call is probably considered "answered" as far as VFX is concerned.

Anyone know for sure?

Cheers Mike

Are you trying to determine whether a caller should be being billed for a calling your system?

The answer really depends how you have trixbox configured.

If you have an IVR answering the calls immediately then the answer is yes. If you have trixbox simply ring phone(s) then typically the answer would be no as the call is not actually connected until you pick up that phone or trixbox diverts that call to VM. trixbox simply sends a SIP 180 (ringing) back to VFX and doesn't actually answer the call.

Thanks sBiddle

I was more concerned with setting the VFX options for missed calls such as voicemail and diversion etc. So I think you have answered the question. If I understand you correctly, provided the call is not passed to the IVR system or a mail box on the Trixbox system, VFX still considers the call as unanswered and will handle the call according to the directions on the VFX Portal.

Might be worthwhile studying the SIP signalling protocols to better understand what communications actually take place between the trunk provider and my station. Guess that would answer my questions.

Cheers Mike
