Enables and disables whether or not the phone uses Draft 15 (draft-ietf-sip-outbound-
15) support for SIP outbound packets.
A SIP User Agent (UA) behind a firewall, reuses an existing connection (usually the REG-
ISTER outbound connection) for the inbound request if the proxy supports it. The UA
uses keep-alive packets to monitor the connection status.
Notes:
• If the Global SIP parameter "Persistent TLS" is set on the phone, then only one TLS per-
sistent connection can be established since the phone uses the local port 5061 for
connection. If the Global SIP parameter "TLS" is set on the phone, more than one con-
nection can be setup since the phone uses a random local port for connection.
• This parameter must be enabled for this feature to start keep-alive for a particular
transport.
