6:11 p.m.
From the transformations documentation:
{s.strip,len}
Return string after removing starting 'len' characters. Parameter 'len'
can
be positive integer or pseudo-variable holding a positive integer.
I tried to use pvar holding len but got an error.
Jul 11 14:51:37 localhost /usr/sbin/kamailio[16905]: ERROR: pv
[pv_trans.c:434]: select cannot get p1
Jul 11 14:51:37 localhost /usr/sbin/kamailio[16905]: ERROR: <core>
[lvalue.c:351]: non existing right pvar
This is part of my config file:
$avp(varname) = '1'; <---- pseudo variable holding a
positive integer
$avp(result) = $(fU{s.strip,$avp(varname)}); <----
s.strip
How can i use variables with transformation ?
