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

Hello,

   After a long time we had a meeting with our university's management and
got a green light to have a proof of concept with open source telephony. Now
I have to select the right software to experiment with...

  Up to now I thought of going with OpenSER for the masses and Asterisk for
voicemail and other media related things. However, from reading around it
seems like FreeSwitch can give me the benefits of both packages. Anyone has
an experience with it?

  Thanks, __Yehavi:

This isn't really the right mailing list for that question.

The answer, though, is, as always:  it depends.

 About the database polling - i think for such a installation you could
 create something like a database to config files script - so not to use
 realtime. This should solve this problem.


No need for that. There's rtcachefriends setting in sip.conf, and if
you have to update user credentials from some interface, just issue
sip prune realtime peer xxx trough manager.

Also, in Asterisk 1.6 res_mysql driver can take advantage of MySQL
master/slave setups, so You can distribute Your database load to
separate read/write hosts.

Atis

2009-03-24 Thread Wolfgang Pichler
Hi,

i do have a request for an installation with about 1800 sip extensions -
as addon to a exisiting system - connected to it using qsig. The
requirement here is also that the system should have SIP over TCP with
TLS and SRTP (snom phones should get supported)
I know there are patches out there to get this working - but have
someone already used these patches with so large installations ?

About the database polling - i think for such a installation you could
create something like a database to config files script - so not to use
realtime. This should solve this problem.

What do you people think about using freeswitch to handle the sip
extensions - do BLF/SLA/SRTP/SIP over TCP TLS - and use asterisk for
interconnection to the other PBX - doing the rest. Have anyone here
already tried freeswitch in such a combination ?

regards,
Wolfgang

 Hello,
  
   Sorry for the delay - was out of office. I also cross-posting it to
 OpenSIPS list.
  
 I have a small pilot (20-30 phones) which also does some sort of SIP
 to PRI transcode for our old PBX. The pilot is base on Asterisk and
 mostly Polycom-501 phones. It works quite well, but I have a few
 minor/missing issues:
 - I have the RPID patch, and unattended transfers fails with it.
 - No SLA, only BLF. I know there is SLA, but it is cumbersome to
 deploy.
 - Confference is limited to 3 participants. I guess I can do more with
 external server but didn't
   manage yet to make it working.
 - No busy dial again which is required by our users.
  
 Now, to the original issue: I tried adding 1000 extensions to the SIP
 database, and then use SIPP to send one REGISTER for each extension.
 After doing so Asterisk still worked, but it was continously accessing
 the database for all these extensions, just polling them. This raised
 a red flag to me, and I decided to check the following config:
 OpenSIPS/Kamailo/etc. as registrar and SIP switch for the phones,
 while using Asterisk only for media related issues (which is the
 common suggestion here). Now, I have new problems:
  
 - SLA works, but very fragile.
 - Not BLF, although I think it will be solve with the dialog handling
 on OpenSIPS 1.5
 - Same confference and busy dial problem.
  
 Next week our management is going to decide (I hope...) how to
 proceed: Do nothing (stay with the Nortel as we are tight on budget),
 go to open source or to a commercial solution.
  
 Although a commercial solution allows me so sleep well at night, I am
 going to recommend the open source direction. If accepted, then I will
 continue the development and you'll hear me quite a lot here asking
 hard questions :-)
  
 BTW, If I didn't say so far: we have around 8,000 extensions on 4
 Notel PBX'es, using around 10 PRI's to the world.

There was at Sam Houston Stat University in Texas, but they have since
transitioned to a Cisco Call Manager system...essentially reversing
their earlier migration.

I gather that this decision was driven by changes in their staffing and
epecially the loss of key staff knowledgable in the ways of Asterisk.

Are those staffing changes the consequence of issues in Asterisk deployment
or is it the opposite (the new staff members that decided to change back to
CCM) ?

Given the cost of reverting to CCM, that would be strange Sam Houston Stat
University in Texas prefers to roll back to CCM instead of finding
appropriate support suppliers.

Maybe actors are still  reading this list and could tell more about it.

I know these days, it's easier to get hudge bargains from vendors ...

2009-03-17 Thread Luis Morales
Very complex installation,

so try to star with:

1) Compatibility of current phone platform + asterisk. For example,
you can convert current extension as sip extension using fxs ports.
This reduces your cost, you don't need buy 8.000 ip phones and install
an new wired network.
2) Planning and do an asterisk cluster based building an locations.
Group extensions by buildings/asterisk servers.
4) Planning and do asterisk network with and distributed dial plan and trunking
5) Try  locate an asterisk specialists
6) believe in asterisk!

Reading this, it's just another flavor of the same medicine.  Both are

In the 3 month's I've been reading this forum, there have been discussions

Hello,

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?

I'd contend that the business model says very little about 
implementation, reliability, scalability.

Hello'

  I am at the same situation as you. I also work at a university and we have
over 8.000 extensions on a Nortel PBX. I also run a small Asterisk pilot.

  I am using a realtime users database and the main problem is that Aaterisk
does too mcuh database access to inquire for the currently registered users.
(I am using direct RTP path between the phones so this is not  a limiting
issue here).

  I am checking now a combination of OpenSIPS and Asterisk, where OpenSIPS
will serve the phones and Asterisk the more complicate things (voicemail,
transcoding, etc.). OpenSIPS still lacks some of Asterisk features, but they
are being worked on.
