[Freeswitch-users] Global Variable Substitution

[Brian Wiese]

Michael:

Here's what I came up with, and it works really well!  I can embed
this in a dialplan or use it at the CLI:

lua ~stream:write(tostring(string.gsub("string_to_search",
"string_to_find", "replacement_string")))

It's awesome!

Thanks for your help!
