<div dir="ltr"><div>I've seen this configuration before - sometimes certain call flows require MTP for devices/integrations on the CUCM side. You don't have to set up multiple listening ports on CUBE, as it's indifferent. On CUCM the two trunks have different source ports. If it's outbound from CUCM only that matters, no CUBE changes are required. If you need inbound calls to have MTP only for certain calls changing the port is the best way.<br>
<br></div>I believe with SIP trunks CUCM will not allow two trunks to the same address with the same source port, but it will allow you with H.323 gateways. However, the choice of which of those gateways is basically random and you may think there are two but it's only using one, but that's a H.323 caveat.<br>

So in CUBE you would do something like this:<br><br><div style="margin-left:40px"><span style="font-family:courier new,monospace">dial-peer voice 1 voip</span><br>
<span style="font-family:courier new,monospace"></span></div><div style="margin-left:40px"><span style="font-family:courier new,monospace"> description Trunk 1<br></span></div><div style="margin-left:40px"><span style="font-family:courier new,monospace"> session protocol sipv2</span><br>

!<br>dial-peer voice 2 voip<br></span><div><span style="font-family:courier new,monospace"> description Trunk 2<br></span></div><span style="font-family:courier new,monospace"> session protocol sipv2<br></span></div><div style="margin-left:40px">
<span style="font-family:courier new,monospace"> destination-pattern 2...$<br></span></div><div><div style="margin-left:40px"><span style="font-family:courier new,monospace"> session-target ipv4:<a href="http://10.1.1.1:5062" target="_blank">10.1.1.1:5062</a></span><br>
<span style="font-family:courier new,monospace">!</span><br></div><div style="margin-left:40px"><span style="font-family:courier new,monospace"></span></div><br></div><div>And then in CUCM you would need to create two new SIP Trunk Security Profiles (Found under System > Security in 8.6), specifying the port in which CUCM should expect to receive the messages. Create your two trunks pointing to the CUBE, using respective SIP Trunk security profiles, and that's how you force an inbound trunk.<br>
<br></div><div>As for the MTP question: You can require MTP for all calls, which can be good and bad. That's no different from H323 trunks to gateways. The require only when needed comes in to play for SIP Early Offer only. And that's a matter of the calling device and whether or not CUCM receives its capabilities or has to make something up using an MTP's capbilities. DTMF relay mismatch (Out of band versus In band) is a different story, and there's no check box for that. That's simply a function of the Media Manager and the MRGL on the SIP trunk, which will correct DTMF mismatches automatically by dynamically using an MTP as needed. So, three different things going on there.<br>
<br></div><div>I hope that helped explain it a bit more. Maybe someone else will fill in some of my gaps.<br></div></div></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Thu, Apr 4, 2013 at 10:22 AM, Erick Wellnitz <span dir="ltr"><<a href="mailto:ewellnitzvoip@gmail.com" target="_blank">ewellnitzvoip@gmail.com</a>></span> wrote:<br>
