Configuring SIP Proxy-based HA

Complete these steps to set up SIP Server HA using SIP Proxy. The procedure applies to both Windows and Linux deployments.

SIP Proxy HA Deployment

To configure the sip-outbound-proxy DN:

1. In the SIP Server Switch, create a DN of type Voice over IP Service. For a multi-site deployment, you must create several DNs of this type, one for each Switch/Site served by a SIP Server HA pair.
2. In the Options > [TServer] section, configure the following mandatory options:
   • contact—Set this option to the SIP Proxy FQDN resolved into a single or multiple SRV records.
   • external-contact—Set this option to the SIP Proxy address using the host:port format.
   • oos-check—Specify how often, in seconds, SIP Server checks SIP Proxy for out-of-service status.
   • oos-force—Specify the time interval, in seconds, that SIP Server waits before placing an unresponsive SIP Proxy in out-of-service state when the oos-check option is enabled.
   • service-type—Set this option to sip-outbound-proxy.

Note: Active Out-of-Service Detection feature (oos-check and oos-force options) must be enabled for SIP Proxy to work.

1. Create a SIP Proxy Application of the Genesys Generic Server type by importing the SIP Proxy Application Template SIPProxy_811.apd from the product installation package.
   A SIP Proxy Application must be created for each SIP Proxy instance.
2. On the Server Info tab:
   • Host—Specify the host on which this SIP Proxy is installed.
   • Port IDs—Specify the following SIP Proxy ports:
     • sip-port, Connection Protocol: sip
     • mgmt-port, Connection Protocol: mgmt
     • http-port, Connection Protocol: http (Optional)
3. On the Tenants tab, add the tenants as necessary.
4. On the Options tab, create a section named sipproxy. In the sipproxy section, add the following options:
   • feature-server-address—Set to the FQDN of the SIP Feature Server.
   • geo-location—Set to the name of the data center.
   • oos-check—Set to 5 by default.
   • oos-force—Set to 5 by default.

To configure the primary and backup SIP Server Application objects for high availability using SIP Proxy:

• In the Options > [TServer] section, configure the following options in both primary and backup SIP Server Applications:
  • sip-address—Set this option to the IP address of the SIP Server interface.
  • sip-outbound-proxy—Set this option to true.
  • sip-enable-rfc3263—Set this option to true.
  • sip-enable-gdns—Ensure this option is set to true.

Important

Both primary and backup SIP Servers must have the same sip-port setting.
