Description
disable
No direction attribute is present in the SDP sent by the
Mediatrix 1204.
The Mediatrix 1204 ignores any direction attribute found in the
SDP received from the peer.
To put an endpoint on hold, a SDP containing a connection
address of “0.0.0.0” is sent.
The method to put a session on hold is in conformance with
RFC 2543.
enable
The Mediatrix 1204 always sends the direction attribute in the
SDP of the initial INVITE.
The initial handshake determines if the peer supports the
direction attribute or not.
•
If the direction attribute is present in the SDP
received from the peer, the Mediatrix 1204 sends
the direction attribute in the SDP for the remainder
of the session.
•
If the direction attribute is not present in the SDP
received from the peer, the Mediatrix 1204 does not
send the direction attribute in the SDP for the
remainder of the session.
If present in the SDP, the direction attribute is preferred over
the connection address to transmit session modification
information.
This method is in conformance with RFC 3264.
