SIS 2.7 builds on the previous SIS releases from OpenCloud.

Some of the SIS 2.7 highlights are:

SIS-SIP failover rate limiting

The SIS now supports rate limiting of SIP session failover adoption. This means if a SIS cluster node fails, the adoption of the active SIP sessions from that node by another cluster node can be throttled. See Rate limiting in the SIS Administration Guide for more information.

Configurable rate-limited SIP response

The status code and Retry-After header value of the SIP message sent in response to a rate limited request are now configurable. See rate-limited error response status code and Retry-After period configuration properties.

New Rhino version required

SIS 2.7 now requires Rhino 2.7.0.
