<p class="MsoNormal">Receiver gets KDMQ message from sender, does the module then expose this to Kamailio as a normal REGISTER request based on user part of to header being ‘usrloc’?<o:p></o:p></p>

<p class="MsoNormal">Was this command issued on the sender or receiver? If the receiver, do you have a call to save() in your config? I believe this is parsed at startup to determine which domains to create in memory - so realistically, the configs on all nodes
