Re: [asterisk-users] Network based transcoding
Sorry for the missing info. Our current architecture is as such: NAT <-> SIP/RTP Proxy <-> *(n) Our concurrent sessions usually peak at between 700-800 channels. On average about 450. I will of course look at the documentation to better understand how a transcoding appliance would fit in our architecture, and thank you so much for the links!!! But generally speaking, does the appliance process/transocde the RTP stream and then forward it to our SIP/RTPProxy? Is it really that easy? :) Again, I will breeze through the documentation to get the detailed "how it works" info I am looking for. Thanks Kindly, N.

Re: [asterisk-users] Network based transcoding
What do you mean with servers? A simple proxy, or a B2BUA (aka Asterisk)? Depending on the basic configuration the "server" might or might not have to deal with some or all of the RTP-streams. The already mentioned company Sangoma usually has good documentation about their products (see http://www.sangoma.com/products/d500-400-2000-sessions/ or http://www.sangoma.com/products/d150-30-400-sessions/) and examples on how to use them. jg -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] Network based transcoding
Hello Gentlemen, Thank you so much for your response, we have adopted transcoding cards in our old system, and they do have some limitations, especially when it comes to concurrent calls. We were looking more into the lines of a scalable multi server router like a cisco 3745. And loading it with maximum number of packet voice DSP modules. A gateway like the ones mentioned would also work fine. Anything but an SBC, since we handle that on our own, and it would just be redundant. What I am kind of unclear about, is how a network appliance would fit into our architecture when it comes to processing the RTP streams before passing it on to our servers for example Please excuse my noob question ;) N.

Re: [asterisk-users] Network based transcoding
Did you already look at transcoding cards? E.g.: http://www.sangoma.com/media-processing/voice-transcoding-boards/ They also have separate boxes (http://www.sangoma.com/products/netborder-transcoding-appliance/). Personally, I prefer to have everything in a single box if there aren't too many parallel calls. jg -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] Network based transcoding
Sangoma has transcoding cards which support access over PCIe or Ethernet.

The reason for my post is to know about solutions people have used in the past, and how it fits into their overall architecture. Our transcoding needs consists mainly of u/alaw <-> g729, and gsm would also be good General details on how this would work, and concurrent capacities are greatly appreciated.
