The SIP-related ini file configuration parameters are described in the table below.
Table 4-7: SIP ini File Parameters
Parameter Description
ReliableConnectionPersistent
Mode
Determines whether all TCP/TLS connections are set as
persistent and therefore, not released.
[0] = Disable (default) - all TCP connections (except those that
are set to a proxy IP) are released if not used by any SIP
dialog\transaction.
[1] = Enable - TCP connections to all destinations are
persistent and not released unless the device reaches 70% of
its maximum TCP resources.
While trying to send a SIP message connection, reuse policy
determines whether alive connections to the specific destination
are re-used.
Persistent TCP connection ensures less network traffic due to
fewer setting up and tearing down of TCP connections and
reduced latency on subsequent requests due to avoidance of
initial TCP handshake. For TLS, persistent connection may reduce
the number of costly TLS handshakes to establish security
associations, in addition to the initial TCP connection set up.
