[asterisk-users] RedFone foneBRIDGE2 2e1 - anyone used it or another TDMoE bridge?

We had many problems with the FoneBridge2-EC as well.  We followed all 
of Redfone's hardware requirements (e.g. a good server, a dedicated NIC 
for TDMoE, a dedicated IRQ, good cabling, etc.) and even let them log 
into our Asterisk box to tweak things, but there were still many HDLC 
errors and glitches in the audio (irritating for voice and show-stopping 
for faxes).

We replaced it with a Digium TE121 and the problems went away.  Faxing 
has been clear and reliable ever since.

(The only issue we've had with the TE121 is echo on voice calls, even 
with the hardware echo cancelling module and lots of zapata.conf tuning...)
