Hello Everyone, We are looking for solutions where the transcoding is abstracted away from our * box (i.e., to the network layer) using some carrier grade gateway, or router. 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. Thanks in Advance, Nick.
Sangoma has transcoding cards which support access over PCIe or Ethernet.

Hello Everyone,
We are looking for solutions where the transcoding is abstracted away
from our * box (i.e., to the network layer) using some carrier grade
gateway, or router.
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.
Thanks in Advance,
Nick.

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.

For anyone else that may be interested in the future, I found a detailed depiction here: http://wiki.sangoma.com/ntg-theory-of-operation Thanks again, N.
