<div dir="ltr"><div class="gmail_default" style="font-family:tahoma,sans-serif">Are you wanting this to all happen within DNS instead of happening within a SIP UA? As far as I understand, if DNS redirected somewhere (SRV or CNAME record for example) it would not change the destination URI the originator is trying to reach. The SIP protocol has redirection codes (such as 301 or 302) but whether or how you might be able to use them depends on the SIP UAs being used.</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 also be able to use something like a SIP normalization script (CUCM), SIP profiles (CUBE), or maybe search pattern replacements (Expressway) to just translate the domain as calls flow in/out. I'm guessing what might be feasible without knowing more of the picture.</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Oct 4, 2019 at 11:10 AM Lelio Fulgenzi <<a href="mailto:lelio@uoguelph.ca">lelio@uoguelph.ca</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

Does SIP allow for domain name substitution?

</div>
<div>By this I mean, instead of advertising or dialing <a href="mailto:coyote@phones.america.acmemanufacturing.com" target="_blank">
coyote@phones.america.acmemanufacturing.com</a> I want to use <a href="mailto:coyote@zing.com" target="_blank">
coyote@zing.com</a></div>

<div>But I don’t want to have to reorganize and reprogram anything. </div>

<div>I just want the DNS to say, “hey, use this domain instead and try again.”<br>
