[Freeswitch-users] Routing calls based on 'Referred-By'

[Anthony Minessale]

if both field and expression are not present in the <condition> tag.  It is
instantly evaluated as true without performing the regex.  Therefore there
is no expansion and the $1 will remain $1.

Notice all you examples that do not work are missing the field=

e.g.
<condition "${sip_referred_by_user}" expression="4473451">
