DR Peer and Remote Site Deployment

The following tasks describe the steps necessary to deploy SIP Business Continuity in the following scenario:

Unless otherwise stated, refer to the Framework 8.1 SIP Server Deployment Guide for information about the configuration options.

Deploying SIP Business Continuity With a Remote Site

See Basic Deployment.

1. On the third switch, configure two Trunk DNs, and configure the contact option on each DN as follows:
   • First DN: contact=<FQDN of DR peer>
   • Second DN: contact=<FQDN of DR peer>
2. On both DNs, do no configure the auto-redirect-enabled option.

All other options can remain the same. However, if you want, you can use the options priority and capacity to indicate the preference of one trunk over the other.

Configure ISCC COF access between the following sites:

• The remote site and the first DR pair site.
• The remote site and the second DR pair site.

Refer to the Framework 8.1 SIP Server Deployment Guide for instructions. Set the following options in the extrouter section on each SIP Server:

• cof-feature=true
• default-network-call-id-matching=sip
