Configuration

If only a single SIP Proxy Server is needed for outbound call routing from the Call Server, choose the SIP Proxy configuration when configuring the SIP Service. In the Unified CVP Operations Console Server, configure the following:

  • Add a SIP Proxy Server and specify the IP address of the server.

Under the Call Server SIP Service settings, configure the following:

  • Enable Outbound Proxy = True

  • Use DNS SRV type query = False

  • Outbound Proxy Host = SIP Proxy Server configured above

When using multiple SIP Proxy Servers for outbound redundancy from the Call Server, configure the SIP Proxy with a DNS name and configure DNS SRV records in order to reach the SIP Proxy Servers. The DNS SRV records can exist on an external DNS Server, or they can be configured in a local DNS SRV record on each CVP server. In the OAMP Console, configure the following:

  • Add a SIP Proxy Server and specify DNS name of the server.

Under SIP Service configuration, configure the following:

  • Enable Outbound Proxy = True

  • Use DNS SRV type query = True

    The DNS SRV record should then be configured with the list of SIP Proxy Servers.

To configure the Local DNS SRV record on each server, under the SIP service configuration, check Resolve SRV records locally.

To use a server group for redundant Proxy Servers:

  1. Select resolve SRV records locally and enter the name of the server group for the outbound proxy domain name.

  2. Under System > Server Groups, create a new server group with two proxy servers that have priority 1 and 2.

  3. Deploy the server group configuration to the Call Server.
