Hi
Does anyone of you configured a SIP trunk between AASTRA and ASTERISK? Do
you know if it works fine?
Also, I want to purchase and install two AASTRA IP PBX, if you can help
please contact me offline?
Thank you
KARIM M.
You can't compare home range with commercial range. Many commercial
buildings have far more challenging environments as far as noise and
blocking surfaces. Going from one floor to another is always worse than
horizontal range for a variety of reasons. For example, antennas are
generally oriented to spread signal horizontally, but not vertically. The
higher the dB gain, the more true this is. My best guess is that a DECT
base probably has a 3dB antenna, which means 3dB more power to the sides as
to the top. Every 3dB is a doubling of the power, because it's a
logarithmic scale. Most commercial buildings employee concrete/rebar
between floors, unlike the simple wood in most homes. Both of those are
terrible for radio signals.
I've covered single-story 2k square foot restaurants with DECT, but they
could barely make the phone work when going next door to their offices in
another suite. In a commercial office environment I've found that roaming
floors with DECT was a total failure.

Have you looked at the Aastra/Mitel SIP DECT system?
They have a reasonably priced DECT system that allows roaming between
access points and 8 simultaneous voice channels per access point.

We deployed the Aastra system a number of years ago and it worked really
well.
