<p class="MsoNormal">The functions extracts username from Request-URI and tries to find all contacts for the username in usrloc. If there are no such contacts, -1 will be returned. If there are such contacts, Request-URI will be overwritten with the contact
that has the highest q value and optionally the rest will be appended to the message (depending on append_branches parameter value).<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Append_branch parameter<o:p></o:p></p>
<p class="MsoNormal">The parameter controls how lookup function processes multiple contacts. If there are multiple contacts for the given username in usrloc and this parameter is set to 1, Request-URI will be overwritten with the highest-q rated contact and
the rest will be appended to sip_msg structure and can be later used by tm for forking.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Does lookup() build the destination set and then I can proceed by doing t_load_contacts(), t_next_contacts() and setup failure route? Any direction is appreciated!<o:p></o:p></p>
</blockquote>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman",serif">Yes, lookup location builds the destination set with all available contacts in location table. A t_relay() at that moment will do parallel forking, ingnoring the q values.
To do serial forking, use t_load_contacts(), t_next_contacts() and failure_route.<br>
