Thanks Alex.
What are the components that I should take into account. Based on answer in
another thread I will be using SIP trunk with an NGN to route the outside
traffic (other than SIP-SIP).
I'll have NATed clients so I'll need the media proxy or rtp proxy as well.
What about their dimensioning? I am sorry if some questions are really
naive. I am new to all this and trying to get hold of the whole technology
stack.

1. Kamailio does not handle RTP, so audio is not a
scaling factor at all;
2. The only scaling factors are transactional memory (TM) and any dialog
state you are keeping;
3. Without I/O wait from external sources, Kamailio can handle a
practically infinite amount of concurrent calls and CPS. But, most
practical applications of Kamailio require database backing;
4. Therefore, performance and throughput will depend almost entirely on
the database you are using for database backing, and any tuning on its
settings. This certainly includes the CDRs and storage, and getting the
most performance out of your database is outside the domain of your
question (or this list);
5. A quad-core host with 8 GB of RAM should be more than sufficient for
Kamailio itself to meet your needs. But most of the answers to your
question don't have much to do with Kamailio.

HI Guys,
can you refer me to some resources which help me dimension the hardware
for a setup.
Total users will be 20,000. What percentage should i assume for
concurrent audio and video calls? What is the standard practice? How
does this all map to the cpu, ram and storage etc. given that I will be
storing the cdrs as well.
In the futute this setup should be scalable so that it should support
200,000+ users within a span of 6-8 months. What would be the ideal
architecture?
Thanks,
Rizwan Khan
