You can add an index to have several TDMoE links and thus several

It using DSP chips makes no difference, it can be done in software
aswell... (in theory, if its open, and the algorithmic complexity is low)
Secondly, I think just the Name explains the difference between TDMoE
and TDMoIP... it's 2 different things... actually TDMoE offers very much
overhead..
TDMoIP is nothing else like IAX2 with trunking, i would say. And a
