Field	Description
SIP Register pacing	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.
TFTP Server IP Address	Enter the IP address for the TFTP Server.
This allows the 6400-S to forward
(proxy) TFTP requests from devices
on the Subscriber side to a TFTP
server on the Provider side.
H232 Gatekeeper IP Address	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.
Use ALG Alias IP Addresses	Not used
ALG Subscriber Interface	Not Used.
Automatic MCCP Re-registration	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.
MGCP Re-registration Rate(s)	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.
