Web API for T20

[Samael]

Hello. Is there any way to automotate via api such process:
1. Account 1 dials or answers the call.
2. In moment of bridging (this moment can be caught via 3rd party service), account 1 puts on hold and phones automatically dial from account 2 to specific address.
3. After dialed party from 2nd accound answers, 1st and 2nd account parties goes to 3way telephone-based conference.

Idea is to get automatic conference on dial or answer with phone service, not PBX.
