Yealink SIP-T19 E2 — понимание слепой передачи вызовов между IP-телефонами [815/841]

Appendix

799

The following figure illustrates a successful call between Yealink SIP IP phones in which

two parties are in a call and then one of the parties transfers the call to a third party

without consultation. This is called a blind transfer. In this call flow scenario, the end

users are User A, User B, and User C. They are all using Yealink SIP IP phones, which are

connected via an IP network.

The call flow scenario is as follows:

1. User A calls User B.

2. User B answers the call.

3. User B transfers the call to User C.

4. User C answers the call.
