[asterisk-dev] ENUMLOOKUP - regex broken?

[Chris Maciejewski]

Hi,

I am using Asterisk 1.6.1 and there is option 's' in this branch:

"Option 's' triggers ISN specific rewriting."

However just tried without 's', and it doesn't make any difference.
I am still getting "4480044800123123 at selfnet.at"

Shall I maybe open a bug for this?

Thanks
Chris
