The DGW firmware handles multiple registration modes, either per endpoint, per gateway, or for the whole unit. Simultaneous registrations are supported for each endpoint or to multiple SIP gateways (a maximum of 5 is supported).
Each endpoint may have its own registration information. You can set information for each endpoint such as its telephone number and friendly name.
Unit registration is used to register a contact not directly related to endpoints. This is generally used to indicate to a registrar the IP location of the Mediatrix unit when it is used as a gateway. In SIP, a registration is valid for a period of time defined by the registrar. Once a unit is registered, the SIP protocol requires the User Agent to refresh this registration before the registration expires. Typically, this re-registration must be completed before the ongoing registration expires, so that the User Agent's registration state does not change (i.e., remains 'registered').
Each endpoint can register to a specific SIP Gateway or register to all configured SIP Gateways simultaneously. DGW handles each registration separately, allowing the registration of individual endpoints to different SIP Gateways.
You can define a specific gateway to register to each endpoint of the Mediatrix unit. For instance, you could set all endpoints of the Mediatrix unit to register to all SIP Gateways simultaneously and set a specific endpoint to register to just one of the SIP Gateways. Using one or more specific parameter usually requires to enable an override parameter and set the specific configuration to apply. Refer to SIP Registration Parameters section.
The total number of registrations is the sum of all the endpoint and gateway pairs.
For most Mediatrix devices, the total number of registrations is limited to 64. However, for the Mediatrix G7 Series, the Mediatrix S7 Series, the Mediatrix 3000 Series, the Sentinel 400, and the Sentinel 100, the limit is 500. If a custom DGW profile is used, the limit can be different depending on what value was defined in the profile. For example, when using a Sentinel 400, up to 500 registrations are possible, but if the profile specifies 200, then the unit will only be able to manage up to 200 registrations.
The Mediatrix unit supports a maximum of 5 gateways. An endpoint configured with All gateways generates as many registrations as the number of gateways. In a setup with 3 gateways, one endpoint configured with All as the gateway name counts for 3 in the total number of registrations. The registrations are enabled gateway by gateway until the limit is reached. Endpoint registrations are used first, then unit registrations. The remaining registrations are not registered and do not appear in the Status table. If the number of registrations exceeds the defined limit, a warning is displayed on the Web interface (as well as in the CLI and SNMP interfaces) and a syslog notify (Level Error) is sent. Adding a gateway or an endpoint triggers a warning message if the total number of registrations configured reached the defined limit
In this example, three gateways (Default, gw1, and gw2) are used with the Mediatrix unit, as displayed in the Gateway Configuration table.
The default ports (0 = 5060 for plain SIP and 0 = 5061 for secure SIP) can be used for two gateways, as long as they are attached to different signaling networks (in the Gateway Configuration table, default/Uplink and gw1/Lan1 use the same ports 0 and 0). If you wish to define another gateway for the same signaling network, a different port should be used than the default ones (Gateway Configuration table, gw2 is attached to the Uplink signaling network, as is the default gateway. For this scope, gw2 is only functional if it uses different ports than the default gateway). When a Gateway Name for a User Name is set to All, this means that 3 registrations are used.
|User Name||Gateway Name||Number of Registrations|
|TOTAL NUMBER OF REGISTRATIONS||12|
