endpoints to IP addresses configured below in the Round
Robin SIP proxies list in a round robin manner. Enable
this feature and submit to view and modify the list. This
is the list of outbound proxies or registrars that are
allowed through Transparent Proxy Mode. The SIP
Server Address above is always included and does not
have to be in this list.
o Registration --
The SIP registration settings allow the device to
manipulate the endpoints registration rate.
o SIP Expires Override (s) --
SIP Expires override field specifies
the number of seconds a registration should be valid. The system uses
this value to re-write the expires value returned from the soft-switch.
The value is entered in seconds i.e. 30 will be 30 seconds.
o Soft-Switch Expires Override (s) --
SIP Soft-Switch expires
override field specifies the number of seconds that should be used
when forwarding registration messages to the soft-switch. This should
be higher than the rate pacing value, otherwise, the soft-switch may
consider the phones registration to have expired. If this field is not set,
the phones value is forwarded unchanged.
o Register Rate Pacing (s) --
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 Register
Rate 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
system. For example, you may set the expires value to 60 and the
pacing value to 1800 to have the phone register to the system every
minute, but only let a register message through to the soft-switch
every 30 minutes.
o LAN/Subscriber Side Gateway --
The LAN/Subscriber side
gateway allows PSTN calls to go out to a local gateway. This gateway
can also be used in survivability mode. The LAN/Subscriber Side
Gateway is used to configure a LAN/Subscriber side SIP gateway to
which calls that are not for a registered phone can be sent. The name
of the gateway is a locally meaningful name. These two fields must
both be filled in, or both be empty.
o Gateway Name --
Enter the gateway name given to the gateway
itself.
o Gateway Address --
Enter the IP or FQDN address of the gateway
