Greetings SIP Implementers, I and a small team of developers are working towards implementing an Open Source SIP B2BUA. We're basically looking for a community of fellow SIP implementors, telecom companies, network operators, carriers and general VOIP enthusiasts to interact with and bounce questions off of.
The reasons we have taken on this project are as follows 1) While there's a wealth of Free and Open Source Software available -- especially in the VOIP arena -- we feel that not nearly enough of it is geared towards network operators and carriers. 2) Between us, we have a wealth of operational experience within the carrier space and haven't been able to find an existing open source project which is as comprehensive as we would like it to be. Our goal as network operators will be to completely replace commercial Session Border Controllers and routing engines. Our current project goals include 1) A ground-up re-implementation of SIP and various protocol extensions and drafts. We chose this route because we had a difficult time finding an OSS SIP stack which met our choice language, scalability, speed and licensing requirements. 2) We want to be able to statefully process 1000 CPS on commodity hardware without media anchoring 3) We are embedding a TCL interpreter and exposing most of the project core and some database access to it. The goal is to provide the network operator with a way to alter SIP messages as they pass through the server and to do things which the core shouldn't be attempting to do (like LNP DIPs and route selection). We will author and release some useful TCL scripts to do some of this stuff. 4) We're designing OpenB2BUA to be used in conjunction with existing open source projects to implement Class-5 feature sets, such as Unified Messaging (asterisk), SIP Registrar & Presence (SER./ OpenSER), and Media Anchoring (rtpproxy). 5) OpenB2BUA will use the RADIUS protocol to conduct all Digest authorization and billing. We're also releasing an OSS billing engine as a companion to OpenB2BUA. 6) Full stateful fail-over. If you lose an OpenB2BUA box another one takes over and your calls stay on-line. If anyone is interested in more information, feel free to contact me until we get our websites set up.
