Transport Protocol sip transport protocol The protocol that the Real-Time Transport Protocol (RTP)
port on the IP phone uses to send out SIP signaling
packets.
Notes:
1.
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 Persistent 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.
2. If the phone uses Persistent TLS, you MUST specify
the Trusted Certificates; 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 4-83 .
Local SIP UDP/TCP Port sip local port Specifies the local source port (UDP/TCP) from which the
phone sends SIP messages.
Notes:
1. It is recommended that you avoid the conflict RTP port
range in case of a UDP transport.
2. 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 configured SIP local port.
For more information, see Chapter 4, “SIP and TLS Source
Ports for NAT Traversal” on page 4-34 .
Local SIP TLS Port sip local tls port Specifies the local source port (SIPS/TLS) from which the
phone sends SIP messages.
Note: 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.
For more information, see Chapter 4, “SIP and TLS Source
Ports for NAT Traversal” on page 4-34 .
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.

Settings (optional)” on page 4-83 .
