[asterisk-users] Large Asterisk installations (~10, 000 extensions), preferably at universities

[Jason Aarons (US)]

Just switching from Nortel to something else may not eliminate
hardware/software failures, or prevent those without experience from
pushing the enter key at the wrong time.  You have to consider the two
professionals actually cost considerably more than just salary, due to
taxes, 401k, benefits and after they gain knowledge of your Asterisk
will they go to a VAR to make big money?  It's a catch-22.

 

I would start with a small pilot of anything (Nortel VoIP, Cisco VoIP,
Asterisk) and use it to build your knowledge/experience and then make an
informed decision versus a rush decision based upon how last week went
with the legacy equipment.  You might find you need to plan for PoE long
term, or have network issues, etc, etc.

Thanks to everyone who replies so far!

 

We have Nortel PBX'es with a support contract from one of the local VARs
(Nortel does not give direct support here). In the last two weeks we had
one of our exchanges down for three half days; one was after a failure,
and the other two were when the technician came to fix remainders of the
original problem and just did a "5 seconds restart which won't even cut
calls". Yeh, the "5 seconds" took 6-7 hours... BTW, they still do not
know what was the original problem.

 

So, why won't we save the big bucks we pay them, hire two professionals
(who cost less) and support an open source code by ourselves? This way
we depend on ourselves only.

 

                         Thanks, __Yehavi:

	Hello,

	 

	  Our university has to upgrade soon its old Nortel PBX's which
holds around 10,000 extensions tied to 5 PBXes. Up to now we thought
about commercial solutions but now there is a window openning for open
source solution. However, I need examples to convince that this solution
is feasible, and preferably at other universities.

	 

	Are there any pointers for such installations?

	 

	                   Thanks! __Yehavi:

	Hello very interesting project you have, however asterisk is not
a registry server, i suggest that you use opensips/opense/kamalio for
your registrar, from where you dispatch to you asterisk servers, inside
a good environment with a controlled network and nice tagged voip flow
you could acheve a good results.
