I have a setup similar to yours; 3 x X100p, Snom 200s, etc. I haven't been too upset about the echo, although I haven't been able to eliminate that issue either. I don't really have any answer for you, but it raises a question I'd like to pose to the list. Are standalone FXO gateways like the Mediatrix substancially better than the X100p solution? They cost more, but might be worth it.

Hi,
Have posted to this list a couple of times and have always received great responses and help. I have a basic * system setup
Using 3 X100P cards with 6 Snom200 IP phones. It was a bit of a struggle getting everything up and running but have been pretty happy with
the flexibility and ease of *. My major problem is one that has been discussed on this list many times before. The echo from the X100P cards is
completely irritating to my users. I have tweaked the system as much as I can, IE: switching tip and ring, using aggressive suppressor, tweaking the TX/RX
settings. There is still echo in the first 0-8 seconds of the call while the echo cancellation is catching up. I understand the problem is that you do not hear this
echo in analog systems even though it is present and it is only heard in the digital system because it is not as fast as analog.
So here is my problem. Our CEO wants me to get rid of the system unless I can provide a solution that will expand and work just as good as an analog replacement
PBX. He came to me with this decision after trying to use the Snom200 speaker phone for a conference call, not a good idea as we all know the speaker on this phone
is not a conference phone replacement. He also was frustrated when he tried to patch a call that came to another extension, which transferred fine, but was disconnected when the receiving party made a switch on their PBX to another extension and it was dropped.
Currently we have 4 POTS lines and I have 1 setup for DSL and the other 3 hooked into the X100P cards, 2 outgoing and 2 incoming, using the DSL as incoming rollover.
We are planning on expanding our business pretty rapidly and he wants a system that will be easy to setup and scale. I know asterisk and VOIP phones are great for this
but the little glitches in the phones, hardware wise, are not supporting my Asterisk decision. I would like to upgrade to a channel bank, and was wondering if anyone has had any echo issues with other digium hardware. I know that the X100P issue comes from not having ECAN DSP in the card. I was also wondering if anyone had any luck adding a conference phone such as the Polycom Soundstation Conference Phone. Any suggestions would be appreciated
