can use inbound leg headers for outbound dial-peer matching.</div>

I’m looking for some advice on how people handle situations with multiple sip carriers. We have a mix throughout our company of DNs ported from 2 different sip providers. If only the first provider could have ported everything, but that didn’t happen. I’m trying
to NOT use a proxy as I don’t want to maintain a giant list of DNs. Also of note is that the DNs are not in ranges…<o:p class=""></o:p></div>

I have a single CUCM 10.0 cluster and 2 CUBEs (one at each data center). But since I’m just labbing this up, I’m just dealing with a testbed cube and test cluster.<o:p class=""></o:p></div>

I have 3 ideas on how to handle this. First was to use a CSS on the line that added sig/steering digits on the front… say… 000001 for carrier 1 and 00002 for carrier 2. Then I could peel them off and send them out to the correct SBCs for each provider. I don’t
like this, it makes it confusing for support staff to see how a call SHOULD exit.<o:p class=""></o:p></div>

My other idea may be a pipe dream… I’ve added a URI to the DN, so, let’s say<span class="Apple-converted-space"> </span><a href="mailto:1000@carrier1.example.com" style="color: purple; text-decoration: underline;" class="">1000@carrier1.example.com</a><span class="Apple-converted-space"> </span>and<span class="Apple-converted-space"> </span><a href="mailto:1001@carrier2.example.com" style="color: purple; text-decoration: underline;" class="">1001@carrier2.example.com</a><span class="Apple-converted-space"> </span>on
the 2<sup class="">nd</sup><span class="Apple-converted-space"> </span>carrier DN. Then I changed the sip trunk to the CUBE to pass this info to CUBE. I see the correct stuff flowing through, and it works with my standard incoming called number and destination
pattern dial peers. Now, I’m trying to figure out how to write a URI dial peer that will do magic things for me. I need to be able to route based on calling party URI… is that even possible? I haven’t been able to find an example like this, so I’m beginning
to grow skeptical.<o:p class=""></o:p></div>

Incoming calls is not an issue. The problem arises when making sure that an outbound call placed from a number from carrier1 goes out a sip trunk to carrier1. If it doesn’t go to the same carrier that owns the TN, either the caller id will be overwritten with
the sip trunks BTN, or I have to apply a diversion header and all calls show up as long distance (and no longer roll up into billing codes).<o:p class=""></o:p></div>
