The Wiki page at http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_bridgecall gives the following example: <action application="bridge" data="sofia/sip/9998881111@sip.yourprovider.com"/> which, for me at least, doesn't work due to an invalid profile error: [ERR] mod_sofia.c:2404 sofia_outgoing_channel() Invalid Profile However, if I replace "sip" in the above action with "external" to specify the external profile, it works. I suspect this is a documentation error rather than a code bug. However, I couldn't find an explanation of the syntax, in particular, whether the profile name has to match a profile defined in the SIP configuration or whether there are profile names defined in the code that have special meanings as well. I'm using the default configuration for now. I could go through the code to find this out, of course, but I thought it better to ask here instead.
