I must be getting closer to getting this to work, because now I get this message: 2012-12-28 15:18:23.596375 [WARNING] sofia_reg.c:2485 Can't find user [ 103@xx.com] You must define a domain called 'xx.com' in your directory and add a user with the id="103" attribute and you must configure your device to use the proper domain in it's authentication credentials. I have a file named conf/directory/xx.com.xml. It's a copy of conf/directory/default.xml, except the include line specifies "xx.com/*.xml" instead of "default/*.xml". I have the conf/directory/xx.com/103.xml file. sofia status says: Name Type Data State ================================================================================================= xx.com alias internal ALIASED internal profile sip:mod_sofia@192.168.4.1:5060 RUNNING (0) internal-ipv6 profile sip:mod_sofia@[::1]:5060 RUNNING (0) external profile sip:mod_sofia@192.168.4.1:5080 RUNNING (0) external::example.com gateway sip:joeuser@example.com NOREG external::flowroute gateway sip:xxxxxxxxxx@sip.flowroute.com REGED ================================================================================================= 3 profiles 1 alias I checked the file log/freeswitch.xml.fsxml, and it has the lines from the "103.xml" file, which has the password defined.
