<p class="MsoNormal">Hi,<br>
<br>
They are different. RURI is the part in request's first line, while the DURI is a an outbound proxy used just to finding the destination at network level (it will not be present in the SIP request).<br>
<br>
by using the set functions you do not create a new branch, you are just changing the RURI and DURI from the default branch. To create a new branch you have to use append_branch().<br>
<br>

<tt>OpenSIPS does full flavor DNS lookup (with NATPR and SRV), but this is internal, and not accessible from script. OpenSIPS implements auto DNS-based failover :</tt><br>

<tt>My understanding is you want the DNS resolving to be done at script level and to have access to the results ?</tt><br>
