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

Subject: [Asterisk-Users] 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  [EMAIL PROTECTED]

Kind Regards.
