[SR-Users] DIALPLAN Module: doubts about regular expression usage

[Stefano Bertuola]

Hi again.

I have a last doubt: the dialplan.translate returns both  Output and
Attributes values.

How is returned (if returned) the ATTRS value with dp_translate() function?

How can I use it in Kamailio script?
