Configuring SIP routes

Last Updated : May 25, 2015 |

About this task

Configure SIP routes for all proxy servers and registrar servers. SIP routes define all proxy and registrar servers with which the Avaya Aura® MS node communicates.

You can configure up to 32 routes for each domain.

The system selects the routes based on the matching domain. If no domain is configured, the system uses the default wild card domain represented by an asterisk (*).

The system uses the Priority and Weight of a route for outbound call load balancing. If multiple routes are configured for a domain, the calls are attempted on the highest priority routes. If the remote server is not responsive or is out of service, the attempted calls can failover to lower priority routes. For routes which have the same priority, the system distributes the load based on the route weight.

Refer to the following parameter definitions for the descriptions of each SIP route setting:

Definitions for SIP route settings

Setting

Description

Enabled

Select to enable or disable a SIP route. Typically, routes are enabled. However, a route can be disabled to remove the route temporarily without reconfiguring the system.

Domain

The name of the domain to which you are adding the route. The SIP route is associated with the domain.

IM Proxy

If there are multiple proxy routes in the domain, route IMs to the route which is enabled.

Priority

The priority value for the route. The default value is 0. The range is from 0 to 65535 with the lowest value having the highest priority. The highest priority routes, which have lower values, are selected first.

Proxy

Select to assign a proxy server role to the route. A SIP proxy server accepts Avaya Aura® MS requests and uses the SIP registrar server to obtain recipient addressing information.

Registrar

Select to assign a registrar server role to the route. A SIP registrar server is a database that contains the location of all user agents within a domain.

Remote Port

The remote port from which the route accepts SIP requests. The default port is 5060.

Transport

Select the appropriate SIP transport (UDP, TCP, or TLS). When you select the transport type of TLS, ensure that a certificate is configured for the SIP-TLS service profile.

Trusted Node

The trusted nodes associated with the route.

Weight

Weight is used to select routes within the same priority level. The default value is 10. The range is 0 to 65535.

Before you begin

You must have configured a SIP trusted node before adding any SIP routes.

Procedure

  1. Navigate to EM > System Configuration > Signaling Protocols > SIP > Nodes and Routes.
  2. In the Routes area, click Add... to add a new SIP route.
  3. On the Add SIP Route page, in the General section, select Enabled to enable the route.
  4. From the Domain list, select the desired domain.
  5. From the Trusted Node list, select the trusted node to associate with the route.
  6. From the Transport list, select the transport protocol that the route uses.
    Important:

    If a transport type of TLS is selected, ensure that a certificate is configured for the SIP TLS service profile.

  7. In the Remote Port field, enter the port number of the remote port.
  8. In the Priority field, set the priority of the route by entering a value.
  9. In the Weight field, set the weight of the route by entering a value.
  10. In the Roles area, select whether the route is associated with the Proxy server, the Registrar server, or both by selecting Proxy and Registrar.
  11. Select IM Proxy to route instant messages only to the route that is enabled if there are multiple proxy routes in the domain.
  12. Click Save.
  13. Restart Avaya Aura® MS for the changes to take effect. Navigate to EM > System Status > Element Status and click Restart.
