SIP Call Signaling Parameter Definitions
Field Name Values Description
SIP Proxy Parameters
Signaling Port port Port number on which the MultiVOIP UserAgent software module will be waiting for
any incoming SIP requests. Default = 5060
Use SIP Proxy Y/N Allows the MultiVOIP to work in conjunction with a proxy server.
Allow Incoming
Calls Through
SIP Proxy Only Y/N When selected, incoming calls are accepted only if those calls come through the
proxy.
Primary Proxy -- This is the preferred SIP proxy server for controlling the traffic of the current VOIP.
Alternate Proxy
1 and 2 -- A first and a second alternate SIP proxy server can be specified for use by the
VOIP for situations where the Primary proxy server is otherwise unavailable.
Proxy Domain
Name / IP
Address n.n.n.n Network address of the proxy server that the VOIP is using.
Append SIP
Proxy Domain
Name in User
ID Y/N When checked, the domain name of the SIP Proxy serving the MultiVOIP gateway
will be included as part of the User ID for that gateway. If unchecked, the SIP
Proxy’s IP address will be included as part of the User ID instead of the SIP
Proxy’s domain name.
Port Number port Logical port number for proxy communications. Default = 5060
Default
Subscriber This is not implemented in the –SS series VOIPs.
This is used as the default end point register with a Proxy.
Default
Username name If the Username is not populated in the Phone Book, this is the Username that will
be used. This works the same for the password as well.
Password password Password for proxy server function. See “Default Username” description above.
Re-Registration
Time 10–65535
seconds 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 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 SIP proxy
“Time to
Live”
value.
(in
seconds) 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.
