This feature provides control over the SIP Max-Forwards header value. The Max- Forwards header is used to limit the number of servers (such as proxies) that can forward the SIP request. The Max-Forwards value indicates the remaining number of times this request message is allowed to be forwarded. This count is decremented by each server that forwards the request.

The Max-Forwards SIP header value is configured using the new parameter, SBCMaxForwardsLimit. The value range can be between 1 and 70 (the default is 10). This parameter affects the Max-Forwards header in the received message, as follows:

•If the received header’s original value is 0, the message is not passed on and is rejected.

•If the received header’s original value is less than the parameter’s value, the header’s value is decremented before being sent.

•If the received header’s original value is greater than the parameter’s value, the header’s value is replaced by the parameter’s value.

This feature provides support for maintaining active SBC call sessions during a blade switchover. Upon blade failure, the standby blade takes over from the previously active blade and current SBC calls are preserved (and not disconnected as in the previous release).
