Hi all, Information on this topic seems a little scarce, so I thought I'd try the list.... Apart from the the coolness factor can anyone explain to me in what situation one would use TDMoE rather than IAX for communication betwwen 2 Asterisk servers?

I guess the key factor is if you need the low almost-tdm latency. Peter

TDMoE, however, is not limited to Asterisk. It's part of zaptel. You can use it to transport a TDM link over an Ethernet network (or IP, with some kind of tunneling), and get it back as a TDM link on the other side (with proper hardware). -- Nicolas Bougues Axialys Interactive
