Hello,

grp_avp is set only when calling the destination/domain select functions.

You have to set the parameter setid_pvar:

http://kamailio.org/docs/modules/stable/modules_k/dispatcher.html#id2495800

And use the variable you set for this parameter after ds_is_from_list().

So, there are two parameters, grp_avp and setid_pvar.

Cheers,
Daniel
