[OpenSIPS-Users] opensips 2.1.2 not accepting transformation in if statement and t_relay()

[Stefan Tobé]

Thanks Ben,
so it is either

   1. using shared variable ($shv(name)) which is *globally available* (and
   adaptable using MI...)     OR
   2. re-initialize variable $var(xyz) every time in *(main) route {}* loop
   with these dashboard values?
