i don't think that empty string is returned, because when i tried to assign result of a transformation on result of another transformation to a variable, i got Nov 12 05:14:08 rautu /usr/bin/sip-proxy[13649]: ERROR: <core> [lvalue.c:356]: lval_pvar_assign(): non existing right pvar if the inner transformation would have resulted in empty string, then also the outer transformation would have done the same. -- juha _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
