[cisco-voip] CUPS SIP Proxy Redundancy

[Kevin Thorngren]

Hi Paul,

You will use DNS SRV records to facility SIP load balancing.  The CVP  
Configuration and Administration guide and CVP SRND provide the details.

Look in the CVP 4.x config/admin guide on page 514:
http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/ 
contact_center/customer_voice_portal/cvp4_0/configuration/guide/ 
cvp40cfg.pdf
or

And, look at the CVP 4.x SRND in the high availability section:

contact_center/customer_voice_portal/srnd/4x/cvp40sdg.html
