Values Description
Direct, In direct mode, all VOIP gateways have static IP addresses assigned to them.
Client, or In registrar/client mode, one VOIP gateway serves as registrar and all other
gateways, being its clients, point to that registrar. The registrar assigns IP
Registrar
addresses dynamically.
The UDP port on which data transmission will occur. Each client VOIP has its
port
own port. If two client VOIPs are both behind the same firewall, then they must
have different ports assigned to them.
If there are two clients and each is behind a different firewall, then the clients
could have different port numbers or the same port number.
(Default port number = 10000.)
50 - If packets are lost (as indicated by absence of an acknowledgment) then the
5000ms endpoint will retransmit the lost packets after this designated time duration has
elapsed. (Default value = 2000 milliseconds.)
0 - 20 Number of times the VOIP will re-transmit a lost packet (if no acknowledgment
has been received). (Default value = 3)
Client Option fields are active only in registrar/client mode and only for client VOIP
units.
-- This is the preferred SPP registrar gateway for controlling the traffic of the current
VOIP.
-- A first and a second alternate SPP Registrar gateway can be specified for use by
the current VOIP for situations where the Primary Registrar gateway is busy or
otherwise unavailable.
This is the IP address of the registrar VOIP to which this client is assigned.

(Default value = 0.0.0.0; effectively, there is no useful default value.)
10000 or This is the port number of the registrar VOIP to which this client is assigned.
other (Default port number = 10000.)
integer The interval between the VOIP gateway's successive attempts to connect to and
60 - 300 be governed by a higher level SPP registrar gateway. The Primary Registrar is
the highest level registrar gateway. Alternate Registrar 1 is second; Alternate
Registrar 2 is the lowest order SPP registrar gateway.
Registrar Option fields are active only in registrar/client mode and only for
registrar VOIP units.
30 – 300 Time-out duration before a registrar will un-register a client that does not send its
"I'm here" signal. Client normally sends its "I'm here" signal every 20 seconds.

Timeout default = 60 seconds.
Y/N Enables MultiVOIP (running in SPP Registrar mode) to operate 'behind' a
proxy/NAT device (NAT = Network Address Translation).
The public IP address of the proxy/NAT device which the MultiVOIP is behind.
