Thank you for your time Anthony. On a similar subject i am working on an ESL application and one of the options i am providing is for the playback application to loop, using the standard "loops" argument. My problem is that the loop count and max loops counter are not provided in the event which means my event handler moves on after one play request.

Is there anything i can do with FreeSWITCH to either lock the execution until all repeats have completed or to add the loop count values to the variables section? Would this be worth pursuing or is the general rule that developers should add this state information outside of FreeSWITCH (i.e. DB etc)? (I'd love to have a go at putting this in to the C source but would probably need some guidance)

ESL application request:

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
