time, in seconds, between re-subscribing. If the phone does not re-subscribe in the time specified for this parameter, it loses subscription.

9. In the "Session Timer" field, enter the time, in seconds, that the IP phone uses to send periodic re-INVITE requests to keep a session alive. The
proxy uses these re-INVITE requests to maintain the status' of the connected sessions. See RFC4028 for details.
10. In the "Timer 1 and Timer 2" fields, enter a time, in milliseconds, that will apply to an IP phone session. These timers are SIP transaction layer
timers defined in RFC 3261.
Timer 1 is an estimate of the round-trip time (RTT). Default is 500 msec.
Timer 2 represents the amount of time a non-INVITE server transaction takes to respond to a request. Default is 4 seconds.
11. In the "Transaction Timer" field, enter the amount of time, in milliseconds, that the phone allows the call server (registrar/proxy) to respond
to SIP messages that it sends.
Valid values are 4000 to 64000. Default is 4000.
Note:
If the phone does not receive a response in the amount of time designated for this parameter, the phone assumes the message has timed
out.
12. In the "Transport Protocol" field, select a transport protocol to use when sending SIP Real-time Transport Protocol (RTP) packets. Valid val-
ues are User Datagram Protocol (UDP) and Transmission Control Protocol (TCP), UDP, TCP, Transport Layer Security (TLS) or Persistent TLS. The
value “UDP” is the default. For more information about TLS, see “RTP Encryption” on page4-79 and Chapter 6, the section, “Transport Layer
Security (TLS)” on page6-16.
13. In the "Local SIP UDP/TCP Port" fiel
d, specify the local source port (UDP/TCP) from which the phone receives SIP messages. Default is 5060.
For more information about this feature, see the section, “SIP and TLS Source Ports for NAT Traversal” on page4-27.
14. In the "Local SIP TLS Port" field, specify the local source port (SIPS/TLS) from which the phone sends SIP messages. Default is 5061.
For more information about this feature, see the section, “SIP and TLS Source Ports for NAT Traversal” on page4-27.
15. In the "Registration Failed Retry Timer" field, enter the amount of time, in seconds, that the phone waits between registration attempts
when a registration is rejected by the registrar.
Valid values are 30 to 1800. Default is 1800.
16. In the "Registration Timeout Retry Timer" field, enter the amount of time, in seconds, that the phone waits until it re-attempts to register
