At http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_bridgecall, near the top under From Dialplan, it says:

Bridge the incoming call to extension 100 and 101. The '%' is used instead of the @ to indicate that the endpoints are registered locally. Separate multiple endpoints with a comma. The ${sip_profile} variable is defined in freeswitch.xml.

<action application="bridge" data="sofia/sip/100%${sip_profile},sofia/sip/101%${sip_profile}"/>

However, I cannot find ${sip_profile} in freeswitch.xml. Is the documentation correct?

Thanks, Lars
