Transport Protocol	sip transport protocol	The protocol that the IP phone uses to send out SIP messages.
		Notes:
		• If you set the value of this parameter to 4 (TLS), the phone checks to see
		if the “sips persistent tls” is enabled. If it is enabled, the phone uses Per-
		sistent TLS on the connection. If “sips persistent tls” is disabled, then the
		phone uses TLS on the connection. If TLS is used, you must specify the
		Root and Intermediate Certificates, the Local Certificate, the Private Key,
		and the Trusted Certificates.
		• If the phone uses Persistent TLS, you MUST specify the Trusted Certifi-
		cates; the Root and Intermediate Certificates, the Local Certificate, and
		the Private Key are optional.
		For more information, see Chapter 4, “Advanced SIP Settings (optional)” on
		page 4-69.
Local SIP UDP/TCP Port	sip local port	Specifies the local source port (UDP/TCP) from which the phone sends SIP
		messages.
		Notes:
		• It is recommended that you avoid the conflict RTP port range in case of a
		UDP transport.
		• By default, the IP phones use symmetric UDP signaling for outgoing UDP
		SIP messages. When symmetric UDP is enabled, the IP phone generates
		and listens for UDP messages using port 5060.If symmetric UDP signaling
		is disabled, the phone sends from random ports but it listens on the con-
		figured SIP local port.
		For more information, see Chapter 4, “SIP and TLS Source Ports for NAT
		Traversal” on page 4-27.
Local SIP TLS Port	sip local tls port	Specifies the local source port (SIPS/TLS) from which the phone sends SIP
		messages.
		Notes:
		• It is recommended that you avoid the conflict with any TCP ports being
		used. For example: WebUI HTTP server on 80/tcp and HTTPS on 443/tcp.
		• By default, the IP phones use symmetric TLS signaling for outgoing TLS
		SIP messages. When symmetric TLS is enabled, the IP phone uses port
		5061 as the persistent TLS connection source port. When symmetric TLS
		signaling is disabled, the IP phone chooses a random persistent TLS con-
		nection source port for TLS messages from the TCP range (i.e.
		49152...65535) after each reboot regardless of whether the parameter
		“sip outbound support” is enabled or disabled.
		For more information, see Chapter 4, “SIP and TLS Source Ports for NAT
		Traversal” on page 4-27.
Registration Failed Retry Timer	sip registration retry timer	Specifies the time, in seconds, that the phone waits between registration
		attempts when a registration is rejected by the registrar.
		For more information, see Chapter 4, “Advanced SIP Settings (optional)” on
		page 4-69.
Registration Timeout Retry Timer	sip registration timeout retry timer	Specifies the length of time, in seconds, that the phone waits until it re-
		attempts to register after a REGISTER message times out.
		If this parameter is set lower than 30 seconds, the phone uses a minimum
		timer of 30 seconds.
		For more information, see Chapter 4, “Advanced SIP Settings (optional)” on
		page 4-69.
