FWIW I've just been IAX2 trunking over to my other server with the 
TE110P in it; works very reliably and I can do a failover to VoIP if, 
say, all channels are busy or something else bad happens. It can also 
give me two-way (inbound AND outbound) failover with timeout forwarding 
from my VoIP provider, where if after xx seconds my external inbound 
IAX2 trunk does not pick up (either by design or ISP failure) the call 
is routed to my Cox DID, then internally IAX2 trunked across to my PBX.

I'm sure all this can be done with the TDMoE method, but I was just 
throwing this at you so can make an informed decision.
