Ricardo, Can you help us in setting OpenSer as a central proxy for multiple Asterisk PSTN GWs, we current have trouble in routing UAs call through OpenSer without being registered with Asterisk.. We like to just have OpenSer registered with all the Asterisk and OpenSer will be the AAA proxy for SIP users, once authenticated through MYSQL db look up, OpenSer will pass the call to Asterisk Box. Asterisk Boxes will then make connection to PSTN or VM service. Please see the script below and comment. Thank you in advance, Michael -------------------------------------------------------------------------------------------------- # # $Id: openser.cfg,v 1.6 2006/02/15 18:23:46 bogdan_iancu Exp $ # # simple quick-start config script #

You may use the following syntax:

subst('/^To:(.*)@(.*)/To:+\1@\2/');

Hope it helps, Regards, Ricardo.

One of my providers requires the To: header to be in e.164 format with a "+" in front of it. Since there is no uac_replace_to() function yet, what are my options for adding this plus symbol?

Before anyone suggests it... I cannot just use another provider. I must find a solution to add the plus symbol.

Thanks, Daryl
