Re: PBX, IVR and Conferencing Platforms From the Same Installation of Asterisk

[Leandro Dardini <ldardini@xxxxxxxxx>]

15k users are quite a big number. To my clients with a large user base I advice always to partition the load on multiple servers. This has a list of advantages, like the ability to power cycle a node without impacting all your users, easier debug and tests of problems and solutions, abiity to scale up to higher number of peers without changing the overall architecture. Obviously you need a software to manage the multi tenant PBX with asterisk and a special setup to handle the high availability and load balanced configuration.

About the fax license, yes, Digium provides fax solutions at cheap prices. However it depends by what you need. If you need T.38 support, Digium fax for asterisk can be the answer, if instead you just need a fax2mail and mail2fax solution, not involving T.38, I always suggest a T1/E1/J1 ISDN network card, far more reliable than a software fax.

Thanks SamyGo and Mitul for your prompt responses.

I have been vested with the responsibility to evaluate Asterisk for a VOIP solution. I was just going through couple of documents and got impressed by the features it has to offer. Our user base is around 15000 and the system should support 1000 concurrent calls, with BHCA projected at 16000.

I plan to use OpenSER for SIP registrations and Asterisk for media processing. RTP Proxy will be used for handling NAT traversal. DNS based load balancing/fail over is preferred over Ultramonkey based one.

I have quite a few more questions on Asterisk.

1. Can we setup virtual private PBX inside Asterisk. I.e. One installation of Asterisk will handle many configured hosted PBXs. Each virtual private PBX should be able to be configured and managed separately.

2. Do we have to buy Fax licence, if Asterisk is to support end-to-end Fax. I.e. Asterisk will not be used in Fax media procession, but only the SIP signals will be handled by Asterisk.

Thanks again for your support.

Kind Regards,

Kannan.

Hi List,

Is it possible for me to setup PBX, IVR and Conferencing platforms from a single installation with Asterisk?

Thanks.
