Cisco SIP IP Phone-to Cisco SIP IP Phone 3-Way Calling
Figure B-11 illustrates successful 3-way calling between Cisco SIP IP phones in
which User B mixes two RTP channels and therefore establishes a conference
bridge between User A and User C. In this call flow scenario, the end users are
User A, User B, and User C. They are all using Cisco SIP IP phones, which are
connected via an IP network.
The call flow scenario is as follows:
5.
User A calls User B.
6.
User B answers the call.
7.
User B puts User A on hold.
8.
User B calls User C.
9.
User C answers the call.
10.
User B takes User A off hold.
