DON'T DO IT!

Taking questionable code, from what appears to be a questionable
relationship, and then trying to extend its life is probably the craziest
way to go about this.

You, personally, are in for a steep learning curve on this.  Having worked
with Asterisk for six years now, I can look back and see that jumping into
complex projects with it at the beginning would have led to many problems.

Getting involved in an existing, and possibly broken system is the wrong way
to start with Asterisk.  I know, because that's how my career in VoIP
started.  I had to unlearn a lot of poor practices I learned from that
system.

But anyway without prior documentation or the ability to get the original
design intention, I think your next step is to go right back to the
beginning, and gather the user requirements and create a design.  Then see
if it was solved properly, or you need to start over, or what.  Without the
basics I don't think you can answer the questions you had.  Once you know
what was needed and why it was custom-written, you'll probably have all
those answers.  Just know that in its basic form, to process calls for a
normal company, nothing is needed other than one Asterisk server.
Everything else is extra, which may or may not be warranted.  I've seen a
number of deployments that seemed geared more towards making a very
profitable complex custom system than just giving the customer the best
value.

Asterisk is a particularly noob-unfriendly product with a lot of pitfalls
and relatively poor documentation.  Don't go into it lightly, and always be
aware that doing it wrong results in anything from system failures to
thousands of dollars in toll fraud costs.

Hi, thanks for your answer. I suppose that both the STUN servers and ActiveMQ

Why would you want to rely on a free stun server which can disappear anytime 
when offering commercial services? I would also deploy my own stun servers for 
paying customers.

> -Why have a separate Asterisk server for the trunk?

No idea. Maybe the question could be: why have two Asterisk servers?
Perhaps for for redundancy/failover?

No idea. I know BigBlueButton uses Apache MQ & Asterisk but I don't know the 
specifics.

No idea.

Server2 Ruby on Rails + CSTele

Server3 Asterisk 1.4.19 + STUN #1

Server4 Trunk (Asterisk 1.4.19) + STUN #2

Server5 Apache ActiveMQ

The system offers PBX services to ~10 small firms and connects via a SIP
trunk to a Telecoms company.

My questions are as follows:

-STUN server – is it necessary (given that there are many free STUN
servers on the Internet), and why two?


Why would you want to rely on a free stun server which can disappear 
anytime when offering commercial services? I would also deploy my own 
stun servers for paying customers.



-Why have a separate Asterisk server for the trunk?


No idea. Maybe the question could be: why have two Asterisk servers? 
Perhaps for for redundancy/failover?



-Is the Apache Message Queue server necessary?


No idea. I know BigBlueButton uses Apache MQ & Asterisk but I don't know 
the specifics.



-My info says that server 2 is running CSTele but I have been unable to
find a process or program that matches this (except for a comment in a
daemon, ast_ami_events.rb, running on Rails server). Can anybody tell me
what CSTele might be?


No idea.

Good luck!

Regards,
Patrick

[asterisk-users] A few (simple?) questions

2011-12-14 Thread Brynjolfur Thorvardsson

Hi all

I've been saddled with recreating a running Asterisk PBX setup (with Ruby on 
Rails). Due to some wrangling between my client and the original developers I 
am not able to talk to the developers themselves but have been given full SSH 
access to their servers!

My questions are regarding their setup - they have functionality split over 
several servers as follows (all running CentOS):

Server1 MySQL
Server2 Ruby on Rails + CSTele
Server3 Asterisk 1.4.19 + STUN #1
Server4 Trunk (Asterisk 1.4.19) + STUN #2
Server5 Apache ActiveMQ

The system offers PBX services to  ~10 small firms and connects via a SIP trunk 
to a Telecoms company.

My questions are as follows:

-  STUN server - is it necessary (given that there are many free STUN 
servers on the Internet), and why two?

-  Why have a separate Asterisk server for the trunk?

-  Is the Apache Message Queue server necessary?

-  My info says that server 2 is running CSTele but I have been unable 
to find a process or program that matches this (except for a comment in a 
daemon, ast_ami_events.rb, running on Rails server). Can anybody tell me what 
CSTele might be?

Many thanks
