[Asterisk-Users] SUCCESS - 512 Simultaneous Calls with Digital Recording

[Waldo Rubinstein]

Matt,

Thanks for the information. If you don't mind answering: are you guys  
developing this solution for your internal needs (meaning serving UAs  
from within your enterprise) or are you planning on offering services  
to the public?

It's not that I'm really interested in your business or business  
model. I'm mainly curious to know how you will deal with potential  
UAs that are behind external NATs. Will you Asterisk "farm" stand  
behind a NAT or will it all be "publicly" accessible where no NAT  
translation or port forwarding will exist? I read the section on  
Asterisk and NAT on the wiki but still left me with some open questions.

In my particular setup, I work in a small call center. I have  
Asterisk behind one NAT with port forwarding on port 5060 and ports  
10000-20000, only because I have 2 remote agents. The rest of the  
agents are in-house. The remote agents themselves are behind other  
NATs (behind their DSL service provider). Some times my Asterisk  
queues have trouble contacting the remote agents. At first, I thought  
I could simply put a SER server on the public edge, but I'm not sure  
if that will really solve the problem. I question this setup in terms  
of stability and security. Even worse, what would happen if my boss  
decides to increase the remote agents?

Thanks again,
Waldo
