<div dir="ltr"><div class="gmail_default" style="font-family:tahoma,sans-serif">Dave, perhaps this is some variation onĀ CSCuv04949 or CSCtr50458. I'm not sure if you're using SRTP for the media, or just using SIP/TLS for the signaling with RTP media. In any case, if you look at the list of caveats in the CallManagerĀ 10.5(2)SU3a release notes - yes the CallManager release notes - you'll see a handful of TLS and SRTP related caveats resolved, especially in the ES train upon which the SU3a build is based. I am referring to the section entitled "Resolved Cisco Unity Connection Caveats in 10.5(2)ES55; base ES for 10.5(2)SU3"</div><div class="gmail_default" style="font-family:tahoma,sans-serif"><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif">You might wish to try pulling up the Mixer and/or CuCsMgr logs for a call while it's working and when it begins to fail and attempt to look for any errors yourself. But in any case, it sounds to me like a TAC case is in order and prepare to supply them the logs if possible.</div><div class="gmail_default" style="font-family:tahoma,sans-serif"><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif">Regards,</div><div class="gmail_default" style="font-family:tahoma,sans-serif">Dave</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Jun 10, 2016 at 10:52 AM, Dave Wolgast <span dir="ltr"><<a href="mailto:dwolgas1@rochester.rr.com" target="_blank">dwolgas1@rochester.rr.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Unity Connection 10.5(2)su2<div>CUCM 10.5(2)su2</div><div><br></div><div>We have a secure SIP integration set up between CUCM and UCxn, which works...for awhile.</div><div><br></div><div>After some number of hours/days, we stop getting rtp.
