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
11. In the "Transport Protocol" field, select a transport protocol to use when sending SIP
Real-time Transport Protocol (RTP) packets. Valid values 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

14. 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 reg-
istrar.
Valid values are 30 to 1800. Default is 1800.
15. In the "Registration Timeout Retry Timer" field, enter the amount of time, in seconds,
that the phone waits until it re-attempts to register after a REGISTER message times out.
Valid values are 30 to 2147483647. Default is 120.
16. In the "Registration Renewal Timer" field, enter the threshold value, in seconds, prior to
expiration, that the phone renews registrations. The phone will automatically send regis-
tration renewals half-way through the registration period, unless half-way is more than the
threshold value.
For example, if the threshold value is set to 60 seconds and if the registration period is 600
seconds, the renewal REGISTER message will be sent 60 seconds prior to the expiration,
as half-way (600/2) > 60. If the registration period was 100 seconds, then the renewal
would be sent at the half-way point as (100/2) < 60.
Valid values are 0 to 2147483647. Default is 15.
17. The "BLF Subscription Period" field is enabled by default with a value of 3600 seconds.
This feature sets the duration, in seconds, before the BLF subscription times out. The phone
re-subscribes to the BLF subscription service before the defined subscription period ends.
Note: This parameter is not applicable to BLF/List subscriptions.
