28.8.7 Interworking SIP re-INVITE Messages

The device supports

communication between endpoints that generate re-INVITE requests and those that do not

support the receipt of re-INVITEs. The device does not forward re-INVITE requests to IP

Groups that do not support it. Instead, it sends a SIP response to the re-INVITE request,

which can either be a success or a failure, depending on whether the device can bridge the

media between the endpoints. The device can also handle re-INVITEs with or without an

SDP body, enabling communication between endpoints that do not support re-INVITE

requests without SDP, and those that require SDP. The device generates an SDP offer and

adds it to the incoming re-INVITE request if it does not contain an SDP and only then

forwards it to the destination endpoint. This interworking support is configured by the IP

Profile parameter, 'SBC Remote Reinvite Support'.

The device supports interworking of the SIP UPDATED message. This enables

communication between UAs that generate UPDATE requests and those that do not

support the receipt of UPDATE requests. The device does not forward UPDATE requests

to IP Groups that do not support it. Instead, it sends a SIP response to the UPDATE

request which can either be a success or a failure, depending on whether the device can

bridge the media between the endpoints. The handling of UPDATE messages is configured

by the IP Profile parameter 'SBC Remote Update Support'.

The device enables communication between endpoints (IP Groups) that do not support re-

INVITE requests but support the UPDATE method, and vice versa. The device translates

the re-INVITE request to the UPDATE request, and vice versa. Note that if a re-INVITE
