asterisk users - Mar 2009 - Asterisk is not designed for University with large user base?

Sounds like a personal preference to me.  Here is the Wiki for SipX.
http://en.wikipedia.org/wiki/SipX

Reading this, it's just another flavor of the same medicine.  Both are
open-source with Commercial support available.

In the 3 month's I've been reading this forum, there have been
discussions
of installations that are at least equivalent to a 10K user university.

Subject: [asterisk-users] Asterisk is not designed for University with
largeuser base?


Hello,

I just had a meeting about a pilot project going on in our University, The 
project manager has done some research in the past year and concluded that 
Asterisk can not scale well to large user base like 10,000 users, thus
Asterisk is not fit for large University environment.

The project manager instead choosed sipX and said it scales well for large
user base.

I had an Asterisk running in my office for small user base, I don't 
have experience with large scale Asterisk implementation. I know little 
about sipX.

Does anyone in the community has any input about this?

Asterisk can scale to 10.000 users. Its probably about the maximum you 
could do on a quite powerful server if you don't need TDM hardware, but 
better would be to use a cluster, the database used would then 
eventually become the limit to the scaling.
I have no experience with SipX so i can't say if it will scale better 
without clustering.

Those links gets passed around every time this topic comes up.

I don't know what metrics led to the conclusion of the project
manager, nor the way things were configured in your particular pilot.

Asterisk-1.6 has dramatically enhanced SIP handling compared to 1.4.
It also has dramatically faster large-dialplan handling.
You can read all about it in the files that come packaged with 1.6.
It's possible (I would dare say likely) that the project manager is
looking at old data, or that the pilot was done with old versions of
asterisk.
