SIP Proxy Parameters 

Password 

Values

:  alphanumeric 

Description

:  Password for proxy server 

function.  See “User Name” description 
above. 

Re-
Registration 
Time 

Values

:  numeric (in seconds) 

Description

:  This is the timeout interval for 

registration of the MultiVOIP with a SIP 
proxy server.  The time interval begins the 
moment the MultiVOIP gateway registers 
with the SIP proxy server and ends at the 
time specified by the user in the Re-
Registration Time field (this field).  When/if 
registration lapses, call traffic routed to/from 
the MultiVOIP through the SIP proxy server 
will cease. However, calls in progress will 
continue to function until they end. 

Proxy Polling 
Interval 

integer 
60 - 300 

The interval between the voip 
gateway’s successive attempts 
to connect to and be governed 
by a higher level SIP proxy 
server.  The Primary Proxy is 
the highest level gatekeeper.  
Alternate Proxy 1 is second; 
Alternate Proxy 2 is the lowest 
order SIP proxy server. 

TTL Value 
in seconds 

The SIP proxy “Time to Live” value.  As soon as a 
MultiVOIP gateway registers with a SIP proxy 
server (allowing the proxy server to control its call 
traffic) a countdown timer begins. The TTL Value 
is the interval of the countdown timer.  Before the 
TTL countdown expires, the MultiVOIP gateway 
needs to register with the gatekeeper in order to 
maintain the connection.  If the MultiVOIP does 
not register before  the TTL interval expires, the 
MultiVOIP gateway’s registration with the proxy 
server will expire and the proxy server will no 
longer permit call traffic to or from that gateway.  
Calls in progress will continue to function even if 
the gateway becomes de-registered.
