Hi, I too can provide you some inputs on this apart from the things which are already mentioned: 1. You may require a media server for playing prompts, announcements, etc 2. Voice mail server to store and play back voice mails 3. Signaling + Media Gateway if you want to connect to PSTN world 4. Any good performance management/monitoring tool (normally part of OSS) to measure and manage the performance of the entire infrastructure to assure zero/minimum downtime Regards, Benjamin. _____ From: Greger V.

It's a fairly big questions you're asking. But basically you're onto it ;-) Ad 1. You should go for something newer than 9.0 Ad 2. You need to decide on your maintenance schedule and policies for upgrades/patching etc. Many larger-scale deployments are based on SER 0.9.x because a) it has proven extremely stable b) it is currently maintained for bug and security fixes and will be for a while. Others choose openser to get more features, but you need to make sure that you can handle testing and deployment of new versions more often. Ad 3. You need a RADIUS server with a user database or you can use mysql (you need mysql regardless of using RADIUS or not) g-) Concy Pereira wrote: Sir, I would like to know how can start a successful SIP base VOIP business.
