6. Enter the TFTP Server Address. This address is used to identify the TFTP
server that contains the images used by IP phones at boot up. The 4300T
performs a TFTP server relay function.
7. Automatic MGCP Re-registration is used to re-register MGCP endpoints
every time the network or system restarts. Enable this feature to
automatically synchronize the softswitch and phones immediately after a
restart. The default is Enabled.
8. The MGCP Re-registration Rate is used to set the number of MGCP RSIP
messages to send per second to the Media Gateway Controller when
re-registration is needed. If the MGCP Re-registration Rate needs to be
changed, enter a value between 1 and 5. Generally, this value does not
need to be modified. The default value is 5 msg/second.
9. The system re-registers clients when it starts up. If any of these
re-registration requests fail, the system will wait for the configured
number of seconds and then retry the re-registration for the clients that
failed. The system will make at most 10 re-registration requests for failed
attempts. If the MGCP Re-registration Retry Delay needs to be changed,
enter a value between 30 and 60 seconds. Generally, this value does not
need to be modified. The default value is 30 seconds.
10. The H.323 TerminalType is used to specify the type of terminal that the
Voice Appliance should use. It can be either endpoint or gateway. The
Maximum Bandwidth specifies the bandwidth to allow for H.323 calls.
Note It is not necessary to program in an FTP server address if your IP phones use the
FTP protocol instead of TFTP to retrieve their images. A relay function is not
needed for FTP as the 4300T will forward FTP traffic to the destination server as
programmed in your IP phone.
