Hi all,
Thank you for all the help till now.
Until now I was trying to setup completely redundant setup with Kamailio + asterisk boxes and for the moment i have the following configuration working.
2x Kamailios (Active/Passive) 2x Asterisks Kamailio is load balancing I can add more boxes if needed MySQL Cluster for all database needs
Now the time has come and I will need to made this setup available for around 10K users. I will need to become an ITSP for an Internet Provider that is missing the telephony part from his package, so I have a couple of questions.
1. Is this setup OK to cover the needs of the customer base ? hardware will be decent 2. The end users will most probably need ATA adapters. What is the best cost effective solution I can go for ? 3. Do I need any other piece of software apart from the SIP Proxy and asterisk as I need the cost of implementation to be as low as possible. 4. Pricing...I can see that there are a lot of plans of the competitors that include 1000 minutes for free...Do you have any statistics what is the avarage % usage of prepaid minutes ? 5. Are there any other "stones" that I might hit and should be aware of ?
Thank you for the information
Best regards, Rumen
1. From what I read - 1 Kamailio server should be good enough for up to 50 K users. 3. You need Kamailio, Asterisk, Database (MySQL), and of course web server (Apache) for GUI - setup of clients, allow clients to see their calls.... You can use on separate server rtpproxy. 4. Pricing, depends of country. For USA, where most calls cost less then cent, 1000 minutes are possible, but for Bulgaria - you cannot offer such minutes.
2. Adapters are very important. There are lot of cheap adapters, which do perfect job, but they did some troubles for me. Small and acceptable troubles, but for me. One of problems we saw is with power supply - after a year or so we saw how some of devices stopped working. And we just replaced their power supply. Also - you can use modified/adapted SIP clients - for desktop, for Android or iPhone. Some of devices, can be used as routers. For me standard is Grandstream - they are not cheap, but they just work - and I had no problems with them. I use also different unnamed devices, and I can try to find mails and addresses of companies for contacts, but we purchased them long ago.
