SIP Devices Configuration
Set Up Ingress Gateway to Use Redundant Proxy Servers
ip domain name <your domain name>
ip name-server <your DNS server>
sip-ua
sip-server dns:<your SRV cluster domain name>
dial-peer voice 1000 voip
session target sip-server
Set Up Call Server with Redundant Proxy Servers
See the Operations Console User's Guide for Cisco Unified Customer Voice Portal on how to configure local based SRV records.
Local SRV File Configuration Example for SIP Messaging Redundancy
Load-Balancing SIP Calls
SIP calls can be load balanced across destinations in several different ways as outlined below:
-
Using the CUSP server, define several static routes with the same route pattern, priorities, and weights.
-
Using DNS, configure SRV records with priorities and weights. Both the DNS client and the server settings must be configured and operating successfully for DNS "A" and "SRV" type queries to work. Configure SRV queries to be used wherever outbound SIP calls are made, such as on the IOS Ingress gateway, on the Call Server itself, and on Unified CM.
 Note | Refer to DNS Zone File Configuration for Comprehensive Call Flow Model for information about load balancing and failover without a Proxy Server. Only the DNS SRV method is supported for load balancing and failover without a Proxy Server. |

Cisco Unified SIP Proxy (CUSP) Configuration
The following configuration shows a CUSP proxy in Unified CVP. The highlighted lines are specific to a Unified CVP solution. For additional configuration details, refer to the Configuring Cisco Unified SIP Proxy Server guide.

Configure Custom Streaming Ringtones
You can configure custom ringtone patterns that enable you to play an audio stream to a caller in place of the usual ringtone. Customized streaming ringtones are based on the dialed number destination and, when configured, play an in-progress broadcast stream to the caller while the call is transferred an agent.
