asterisk users - Oct 2005 - Looking for advanced consultant services

Hi,

 I have a meeting with an important customer in a couple of days and I am 
aware that most of their questions are going to be related about scability 
of Asterisk. We want to propose this customer to integrate Asterisk with 
SER, but I have a loot of complex doubts that I would like to known before 
this meeting.

I would like to contact with a busines that has experience with large 
installations and has already work integrating Asterisk with Ser.  My 
customer is very worried about NAT Tranversal problematic, he is thinking 
on focus the service on SER, so use SIP clients, but he would like to be 
able to migrate every user to IAX in a a near future. 

I have questions about a solution that is NAT Transversal,  what 
beneficits/problems will give me products as JASOMI (why are better than 
STUN), STUN installation considerations....etc. Also.. Should I consider 
SIPFOUNDRY instead SER ? 

If anyone is interested, please send me your hourly rates as well as 
details about your implication with large scale proyects, with Asterisk; 
SER &STUN, etc, so I can evaluate to whom forward my questions (I do not 
want to spent time with people who have not enough expertise on this). You 
can contact me at  rrhh@sipspain.com. 

Kind Regards.

Hi, there,

 

At least, Ser + proxy (I gave Asterisk up) can do large scale for sure by
multi proxy server applied. We can let each proxy server to handle 60-70
calls at same time because it's limited by 100M NIC (150k/s of a 2ways
G711U,) amd hundreds calls of g729. Basiclly, more calls, more servers
applied. By using DNS SRV, you can configure as many servers as you like.

 

To make our customer happy with voice and fax, we are using G729 as primary
codec for sip call. Low end computer is enough for media proxy. To handle
those G711 calls, P3 server(single or dual CPU) is enough and is very
cheaper from ebay. At our each sites, we are going to use few Dual PIII
1.1-1.4G server as local media proxy servers.

 

SER is a proxy and it should handle huge SIP traffic if you don't take too
many database actions (real time charge and billing, complicated
application, etc. for each call). My idea is just to make ser as easy as a
regular SIP proxy.

 

 

 

Regards

 

 

Leon Sun

Hello, we can help you with this. Setting up large Asterisk and SER 
clusters is our speciality. We've done 4 high availability and fully 
redundant systems this year, as well as quite a few smaller ones.

NAT traversal is no problem; we can do this on SER. We generally don't 
use STUN, as it's not necessary.

We also have a full featured user and reseller management system with 
integrated billing. We have a demo of the beta test version up at:

http://guest:guest@itsp.demo.integrics.com/

and will be making a formal product announcement once we have more 
marketing material. I'll send you a separate email with a feature list 
and road map.

We can also do custom development to your specifications. I'll send you 
an email off-list with pricing.
