SIP Call Signaling Parameter Definitions

Description

Port number on which the MultiVOIP UserAgent software module will be waiting for any incoming SIP requests. Default = 5060

Allows the MultiVOIP to work in conjunction with a proxy server.

When selected, incoming calls are accepted only if those calls come through the proxy.

This is the preferred SIP proxy server for controlling the traffic of the current VOIP. 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. Network address of the proxy server that the VOIP is using.

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.

Logical port number for proxy communications. Default = 5060

This is not implemented in the –SS series VOIPs.

This is used as the default end point register with a Proxy.

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 for proxy server function. See “Default Username” description above.

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.

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.

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.
