Hi Paul,<div><br></div><div>Please see inline comments....</div><div><br></div><div>I re-read your original email bit closer. Are you using CUPS just for SIP Proxy or are you also using it for presence? </div><div><br></div><div>If just as a SIP Proxy you might be ok but my understanding is that the two CUPS servers must be co-located with their CUCM Pub. I believe this is for presence functionality. Not sure (but doubt) if it will affect SIP Proxy functionality. Please verify with you Cisco SE.</div><div><br></div><div>Let me know if you have any questions.</div><div><br></div><div>Kevin<br><div><div><html>On Mar 27, 2008, at 3:26 PM, Paul Dillon wrote:</html><br class="Apple-interchange-newline"><blockquote type="cite"><p>Kevin,</p><p>I am still confused here after reading the PDFs:</p><p>In Active Dir DNS:</p><p>I need to add 2 DNS SRV entries to the DNS: of the same name but with diifferent weights and priorities.

Also you will need to enable Use DNS SRV type query. <br><blockquote type="cite"><p>Do I change the SIP-UA SIP Server to the DNS SRV address hence requiring DNS on gateways</p></blockquote>Honestly I never set this up. In my testbed my ingress GW was another CUCM generating calls. I am not sure of the exact mechanism but you will configure the outbound calls on the ingress GW to use the name of the DNS SRV record.<br><blockquote type="cite"><p>Similarily on the Call managers do I use the same DNS name in the SIP Trunk instead of the SIP Proxy IP address and also requiring DNS on CCM. Or do I add a second SIP trunk for the secondary Proxy</p></blockquote>Just use one trunk and configure the destination as the name of the DNS SRV record and check the destination address is a SRV. The destination port will be 0.<br><blockquote type="cite"><p>Thanks</p><p>Paul<br><br></p> <div><span class="gmail_quote">On 3/21/08, <b class="gmail_sendername">Kevin Thorngren</b> <<a href="mailto:kthorngr@cisco.com">kthorngr@cisco.com</a>> wrote:</span> <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">Hi Paul,<br><br>You will use DNS SRV records to facility SIP load balancing.
