[OpenSIPS-Users] Question: how to return string from module function to config script?

[Elaine Huang]

Hello Ovidiu,

Thanks for your reply. Reading the linked doc it seemed to me exported
functions can only return integers.

I don't quite get the dialplan dp_translate function, how do I decide what
dialplan id to use, and what's a translation rule?

Should I create my own pseudo variable and store the string there for
scripting access? Sorry for all the questions.


Cheers,
Wenshan
