The VoIP community is gaining speed, with good projects like Callweaver and Freeswitch! It is good to see that projects can evolve without the proprietary timers needed for the Digium version of Asterisk. It is fully understandable that Digium wants Asterisk to be dependent on their phone cards, but it hinders the VoIP development.
T.38 is important, even though the fax machine should have been replaced by a PKI system where you could send authenticated mails. It would also save the environment for prints…
The Callweaver (previous openpbx) can also be used as an session border controller. The SBC is really just a firewall, but with specific rules and algorithmes for VoIP. It is a product for the time beeing until the VoIP standards are fully complied by the different vendors. The SBC market will exist as long as all the vendors follows their “own” implementations of the standards.
Freeswitch is not based on Asterisk, but tried created better with the faults and drawbacks of Asterisk in mind. It can be used as a simple switching engine, a PBX, a media gateway or a media server to host IVR applications using simple scripts or XML to control the callflow. FreeSWITCH supports many advanced SIP features such as presence/BLF/SLA as well as TCP, TLS and sRTP. It also can be used as a transparent proxy with and without media in the path to act as a SBC (session border controller) and proxy T.38 and other end to end protocols.
I’m positive to the different flavors and distributions to Asterisk and hope they can learn from each other and bring the world forward!
