h1. Connecting to conversation additional participants *Connecting to conversation additional participants* (also known as n-way conference) - a process of creating a conference during a call, using certain DTMF combinations and dynamically attaching to conference new participants. This [[VAS]] could be activated from User side. In case if user participates in a call through a call via originator or terminator (for ex. during [[Call forwarding]], then he won't be able to activate this [[VAS]] due to billing constraints. A process of connecting additional participants looks like follows: 1. During a call one of participants enters certain [[DTMF combinations during connection|DTMF combination during connection]] (by default *5). 2. After DTMF has been recognized,both subscribers are put into dynamically allocated conference-room. Both subscribers hear audio message that they have been placed into conference mode. As far as both subscribers appear in conference-room, they can continue communicating. 3. Next, any of users - participants of the conference, say user А, can enter DTMF #. On this event, a voice prompt is played to user А to enter a number of new conference participant. Next dial tone is played. User B hears music on hold meanwhile. 4. User А enters number of user C. To begin a call you need either to press # or to wait a few seconds. After this system will invoke outgoing call to user C. New call is written off subscribe A balance. 5. After successful dial, user А can talk to user C, enter *5 and both subscribers will be placed to conference to user B, which already waits for them. 6. In case if user A couldn't reach user C, the system returns him back to conference to user B. 7. In case if user A has reached user B, but decided not to invite him to conference, he could enter DTMF *6. After this outgoing call will be hanged up, and he will return back to subscriber B. Step-by-step instruction of configuring this [[VAS]] is located in section [[Configuring creating conference during conversation]]. [[Подключение в разговор дополнительных участников|Русский перевод]]
