What is your recommendation for
solid-state appliance for asterisk for large number or branch offices (5-20 extensions)? Tamer Zanaty From:

[mailto:[EMAIL PROTECTED] On Behalf Of Greg Renouf Lee, I have managed Asterisk site
implementations (with sip phones) of up to 750 users- once the systems were
tweaked & stabilized, Asterisk performed very reliably for us. For large sites (200+ users), I use dual
Xeon 3ghz with 1mb cache & 2GB memory. I have worked with brand-name
servers (Dell, HP) and generic servers- generic servers always seem to work best
as there are less opportunities for interrupt issues with Zaptel cards. For smaller sites (50 or less) there are
two options: use less powerful servers, or solid-state appliances (no fans, CF
memory). The solid-state option is most preferable, but you may find it
difficult to find a vendor who can provide you onsite support. For very small sites (10 or less), and
home workers, it would probably best to not place a server onsite (where it is
not necessary to have local PSTN connectivity). If you don’t need the
advanced features of a sip/office phone, I would strongly recommend you try the
IAXY, or one of the other IAX devices. It will probably be necessary to upgrade
the ADSL lines to full SDSL, and upgrade to at least 20:1 or 10:1. Make
sure that the onsite routers are able to manage IP prioritization for SIP or
IAX. You are not crazy to try this, but you are
definitely taking a more risky path (you won’t get fired for buying
IBM). You can be successful as long as you carefully manage the project carefully,
and thoroughly review your potential risks. If you succeed, you can save
your company a lot of capital while providing them with a very flexible
platform. -GSR From:

On Behalf Of Lee Mason This is my first post to this list and I hope that I am
targetting it at the correct one so here goes: I am just about the embark on a technology pilot of
Asterisk. The structure of the network is that we have one main office with a
100Mb pipe to an ISP who hosts various systems in a central data centre. They
also provide us with a private IPVPN network to about 350 sites. The links to
these sites are 512Kb 50:1 ADSL at present. The purpose of the pilot at present
is just to prove the technology and decide what we need to do with our
infrastructure to support VoIP. I have a couple of questions. 1. What is the largest Asterisk deployment to date? If the
pilot is successful we are looking at about 100-150 users in a Head Office and
about 500-600 users on the remote sites, plus about 50 other mobile users
coming in across the internet. 2. An I crazy even to consider this? 3. Has anyone got any experience of doing this sort of thing
and any experiences they can share with me? I am sure that there are many other questions, but these are
a start. Many thanks, Lee Mason WOW! Stella
