Long delays can be introduced when using DNS in the Unified Presence server. 
Additionally, configuration is made more complicated when DNS is used. For example, 
you must configure reverse DNS lookups, and special ACL and presence settings.  

It is strongly recommended to disable Unified Presence Server’s DNS to simplify 
configuration and decrease the possibility of introducing delays. When installing Unified 
Presence Server, the install prompts you to enter the DNS server (primary and secondary).  
You may leave the DNS entries blank to disable DNS altogether. 

You must configure your routes in Unified Presence to use IP addresses if you disable 
DNS. Unified Presence Server DNS is not necessary when all routes are configured with 
IP addresses. 

For more information on the delay issue on how to disable the Unified Presence DNS 
server, see the Cisco Unified Presence Server Release Notes at: 

Use UDP transport when you are using SIP with Unified CVP to prevent timing issues 
and longer failover response times.  Timing issues can sometimes occur when using TCP 
as the transport protocol. Additionally, there can be slower failover response times when 
using TCP. These issues are not present when using UDP as the transport protocol. 

Note that TCP transport is the default selection on the Unified Communication SIP Trunk. 
Setting this to UDP for the trunk that interconnects with Unified CVP may resolve timing 
issues seen with TCP.
