[Serusers] @to.tag="" not detecting empty To tag?

Hi folks,

I am moving production to SER2 rc 2.0 and can not make @to.tag=="" to work.

For example, in initial INVITEs:

# if this is an initial INVITE (without a To-tag) we might try another # (forwarding or voicemail) target after receiving an error if (method=="INVITE" && @to.tag=="") { xlog("L_ERR","LXLOG: initial INVITE (no Totag) setting FAILURE_ROUTE"); t_on_failure("FAILURE_ROUTE"); }

FAILURE_ROUTE is never called.

While next check works (in the sense the failure route is processed).

if (method=="INVITE") { xlog("L_ERR","LXLOG: INVITE setting FAILURE_ROUTE"); t_on_failure("FAILURE_ROUTE"); }

So I am wondering whether @to.tag=="" works for empty To tag....can anyone confirm it?

Thanks, Samuel.
