[Freeswitch-users] uuid_setvar prefixing

[Callum Guy]

Hi All,

When using inbound ESL method uuid_setvar I understand the variables will
get prefixed with "variable_" such that...

uuid_setvar chan123456 MyVar MyVal

...reports in the next event as:

[variable_MyVar] => MyVal

My issue is that i'm building an event based system that stores custom
channel data using this operation and i don't want user entered variable
names overwriting exiting channel data.

I am counteracting the above concern by simply adding my own prefix to all
set/get operations but I am still interested in finding out the
significance of these variables and if its only FreeSWITCH modules (i.e.
"playback_terminators" for playback application) that populate those in the
"variable_" list or if these are used deeper in the core as well?

Any further information would be really useful, thanks,

Callum
