Description
If the SIP Expires override field is set to a
lower value, the number of registration
messages may overload the soft-switch.
In order to prevent this, you can set the
SIP Register pacing field to the number of
seconds to wait before forwarding a
register message from one phone to the
soft-switch. Any register messages
received before this time will be locally
answered by the 6400-S. For example,
you may set the expires value to 60 and
the pacing value to 1800 to have the
phone register to the 6400-S every
minute, but only let a register message
through to the soft-switch every 30
minutes.
Enter the IP address for the TFTP Server.
If an H.323 ALG is needed, enter the
address (either an IP or URL) for the
H.323 Gatekeeper. This address should
be reached via the Provider side Ethernet
port.

Not Used.
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.
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.
