Brainslayer, Is there any plans to add support for the SER PDT module. It allows for dialing rules for multiple SIP VoIP providers. pdt: This module translates numerical codes into domains and update accordingly the R-URI. The module looks up at the R-URI part of a message and if the user part begins with an established prefix it will update the URI. Updating the uri consists of: read the code after the prefix from the user part of the uri and keep the rest as the user part of the new uri. The host part will be the domain matched for the leading code. Code: [<prefix>]<code><userid><:password>@<mydomain.com> ... and the result will be: <userid><:password>@<domain[:port]>... Example 1-1. prefix=2 code=3330 domain=iptel.org [email]firstname.lastname@example.org[/email] => [email]email@example.com[/email] The code is always ended with a special digit (a parameter of the module). This digit will not be inside the code at all. It looks real sweet. Any ideas? http://www.voip-info.org/wiki-SIP+Express+Router shows all of the different modules.
