Yxa 1.0 RC1

Yxa is a SIP stack and a set of SIP server applications written in Erlang/OTP. The SIP stack is RFC3261 compliant.
Among the features implemented are SIP registrar, SIP router, forking, CPL, IPv6, TLS, ENUM, PSTN gateway access control and modular user database backends.
The main goal of the project is to create a robust SIP server platform that can scale to tens of thousands of users, be interoperable through standards compliance, and still have short time-to-market for new features due to the use of a high level language.
Main features:
- RFC3261 compliant SIP-server, capable of everything a generic domain needs :
- Registrar that keeps track of your users
- Handles incoming SIP requests to your domain
- Handles routing of requests from your users to remote domains
- TCP, UDP and TLS (including SIPS) support
- Automatically maps e-mail addresses of your users to their SIP addresses, if you have the e-mail addresses in LDAP
- Handles multiple domains using a single server instance
- ENUM support for PSTN-bypass whenever possible
- IPv6 support
- Forking, both parallel and sequential
- CPL (RFC3880) support for advanced user-control of events (currently incoming calls only)
- Modular user database, currently with LDAP, Mnesia, MySQL and text-file backends
- PSTN destination access control (per user or for anonymous users
Enhancements:
- Various bugs in the draft-Outbound implementations have been fixed.
- The pstnproxys application logic has been updated to suit some real deployment scenarios.
- The test framework has been greatly enhanced.
