[Freeswitch-users] Briding two sip-trunks

[Michael Collins]

Is security an issue? Or will all calls behave exactly the same? You can use
acl.conf.xml for letting in only certain IP addrs if need be. In any case,
you could add something like this in conf/dialplan/public.xml:

<extension name="fwd to external profile">
  <condition field="destination_number" expression="([your DID number])">
    <action application="bridge" data="sofia/internal/$1 at x.x.x.x:yyyy"/>
  </condition>
</extension>

Where x.x.x.x:yyyy is the IP address and port that Lync is listening on.
Give that a try and see what happens... :)
