Hi Everyone ! I have been using Asterisk for 2 to 3 months now. I have made peer to peer calls using Asterisk both with H.323 and SIP. Now there is a requirement that I have to setup asterisk in my office supporting upto a 1000 extensions (pstn or IP endpoints). Now the question that I wanted to ask was that is it possible to deploy Asterisk with so many extensions ? Has anyone ever used Asterisk in such situations ? Are there an results available of Asterisk's stress testing or stuff or any expereiences related to that ? I have come across emails suggesting to use a third party proxy, such as SER, for large scale deployments. Does this mean that the embedded proxy does not support large number of extensions? I would be really greatful if anyone could help me in this regard. Usman.
