[Asterisk-Users] Scaleable Solution for small office

[Ryan R. Fligg]

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
