Three-party conference
•
Mode
– operation mode of three-party conference. Two modes are possible:
•
Local –
conference assembly is performed locally by the device after pressing ' CONF';
•
Remote (RFC4579)
– conference assembly is performed at the remote server; after pressing
'CONF', 'Invite' message will be sent to the server using number specified in the 'Conference server'
field. In this case, conference operation complies with the algorithm described in RFC4579.
•
Conference Server
– in general, address of the server that establishes conference using algorithm
described in RFC4579. Address is specified in the following format SIP-URI: user@address:port. You
may specify the 'user' URI part only—in this case, 'Invite' message will be sent to the SIP proxy address.
