SIP is required if you want intercluster presence. Although if you really wanted to you could create a special CSS for Subscribe that used the SIP trunks and actual calls/media could use h323.<br><br><div class="gmail_quote">

I've had the same experience, and feelings towards sip. H323 > SIP (imo)<div><div></div><div class="h5"><br><br><div class="gmail_quote">On Mon, May 18, 2009 at 6:57 PM, Jason Burns <span dir="ltr"><<a href="mailto:burns.jason@gmail.com" target="_blank">burns.jason@gmail.com</a>></span> wrote:<br>

I find it easier to troubleshoot and understand (but that's just personal preference I suppose), and everything usually "just works" with the H.323 setup.<br>

There was a reason we went with H.323 during our CCM 4 to UCM 7 migration, and I think this was one of them.<br>

<br>
I'm looking setting up an ICT to another CUCM cluster, just wondering if using SIP instead of H323 is now a better option?<br>
<br>
Any thoughts on this?<br>
