[OpenSIPS-Users] Using dispatcher's ds_select_domain with a variable

[Bogdan-Andrei Iancu]

Hi Jock,

The ds_select_domain() function expects to receive (as set id) and 
integer value (directly or via a pv).

In your case $var(beep) contains a string and not a number. Try:
    $var(beep) = $(ru{s.substr,27,4}{s.int});

to force the value as number.

Regards,
Bogdan
