MAS commissioning
The platform has an internal domain called the wildcard domain, which is represented with an asterisk and is the default domain if no matching domain is found.
SIP accounts
SIP accounts are used for application registration in the SIP network. The MAS registers all accounts against the registrar servers. For information about the servers, see SIP registrar servers (page 19). You can view, add, and delete SIP accounts.
SIP trusted nodes
MAS processes SIP traffic from trusted nodes only (for example, proxies and gateways). Any requests from a nontrusted node are rejected. You can view, add, and delete trusted nodes.
Attention: If you add or delete a trusted node, you must restart the platform for the change to take effect.
SIP routes
Use SIP routes to define all proxy and registrar servers with which a MAS node communicates. You can configure up to 32 routes for each domain.
SIP proxy servers
A SIP proxy server accepts MAS requests and queries the SIP registrar server to obtain the recipient addressing information. The proxy server then forwards the request directly to the recipient if the recipient is in the same domain or to another proxy server if the recipient is in a different domain.
The MAS platform uses proxy server routes to route outbound SIP requests to the appropriate proxy server for outbound traffic load sharing and failover. Routes are selected based on the domain (or subdomain) lookup. If no matching domain is configured, the default wildcard (*) route is used. For example, if an outbound call is made to janedoe@techtrial.com, the routes associated with the techtrial.com domain are selected.
On the first routing attempt, the MAS platform selects active routes that are online based on the lowest priority only. The weight is used to select routes within the same priority level. Route selection from the next priority level is chosen automatically only if the lower priority routes are either offline or fail to respond.
For load sharing configurations, you can define multiple routes with the same priority. For failover configurations, configure the primary routes with priority = 0 and weight = 10 and configure the secondary routes with priority = 1 and weight = 10.
