This feature is enabled by the new parameter, UsePingPongKeepAlive. In addition, the
maximum interval after which a CRLF Keep-Alive (“ping”) is sent after a received
“pong” is configured using the new parameter, PingPongKeepAliveTime (5 to
2,000,000 sec; default is 120). The device uses the range of 80-100% of this user-
defined value as the actual interval. For example, if the parameter value is set to 200
sec, the interval used is any random time between 160 to 200 seconds.
Notes:
• The Keep-Alive mechanism begins after a successful response from a SIP
REGISTER request.
• The device sends a CRLF message to the Proxy Set only if the Proxy Keep-Alive
feature (EnableProxyKeepAlive parameter) is enabled and its transport type is set
to TCP or TLS. The device first sends a SIP OPTION message to establish the
TCP/TLS connection and if it receives any SIP response, it continues sending the
CRLF keep-alive sequences.

The maximum number of row entries in the SIP Media Realm table (CpMediaRealm
parameter) has been increased from 16 to 64. This now accommodates the increase
of the Multiple Interface table (over 16 interfaces), allowing each IP interface to be
assigned to a different SIP Media Realm.
