[Freeswitch-dev] Help on switch_channel_expand_variables(switch_channel_t *channel, const char *in)

[Anthony Minessale]

say you had 2 vars test1=foo and test2=bar

it would turn the string "${test1} ${test2}" into "foo bar"
if the returned string does not return the exact pointer that was input, it
must be freed.
