Hi Mike,
It hasn't been two weeks work. Just bits and pieces over two weeks
as I make a change and see how reliable it is.
Also there is a very large area to cover that has good wifi
coverage already.
As far as the keepalive settings, it seems there is a very good
chance that Android basically can't play well with WPA enterprise
authentication. Since setting up a few access points with WPA
personal the phones are at last holding the connection reasonably
well. I'll report back on that over the next few days as I know
more.
And lastly, so far battery hasn't even been close to an issue...
of course if it all ends up working well and more time is spent on
calls it could deteriorate but at the moment it's only around
20-30% per day, basically in line with what would be expected of
them as a cell phone.

Well, if cost is no option, and at this point you've
blown 2 weeks... bite the bullet and get some Polycom 8440's.
Heavy duty and they have the Polycom SIP firmware that is known
to work well.
Bria should have a setting for WiFi keepalive. I thought
csipsimple also had such a setting...
Battery will be your issue with ANY wifi device. This is why
SIP DECT phones exist.

Hi all,
I've being working with this now for about two weeks
with some good and bad and mixed results. This email
will hopefully be a summary of where I have gotten too
and also a request for suggestions and experiences from
others.
So the short summary would be that they very work
well when the Android OS doesn't put the wireless to
sleep.
The longer version is that the problem is divided
into two parts: maintaining the wireless connection and
the SIP soft phone.
Wireless:
- The biggest problem I have encountered is keeping
the wireless alive and connected. Android itself
constantly wants to shut it down to save battery and
it has to stay on. The Wifi Fixer app (https://play.google.com/store/apps/details?id=org.wahtod.wififixer)
possibly helps with this but then I've found that
Android itself seems to have a bugs connecting
reliably to WPA enterprise access points. I am in
the process of testing now with a WPA2-Personal
setup using multi-SSID capable WAPs to see if they
work better this way. Any suggestions would be
greatly appreciated.
- I've also found it can take a very long time to
switch WAPs but I think that is because our
environment is almost too good and you can still get
a very marginal signal from one access point when it
should've long ago switched to a closer one.
Softphone apps:
- Acrobits Groundwire has the most reliable and
functional client but attended transferring is a
massive pain.
- Bria has the simplest interface for transferring
but has a few (minor) interface stupidities and some
major idiocies. If it looses a connection to sipX
(from the wireless being unavailable temporarily) it
throws up an error and doesn't reregister until you
notice and clear it. Basically this makes it totally
unreliable and useless as a softphone. Also it's
setting for keeping the wireless active doesn't seem
to do anything.
Hardware:
So far we've tested on two units purchased as prepaid
phones but without the SIM card inserted.
- Samsung Galaxy Y (AU $129) is terrible as a
regular phone and worse as anything else. It
probably won't even be usable as a test unit later
and will be thrown in the rubbish.
- LG Optimus Spirit (AU $99 and available at $49.50
for a while) is very very nice. Speaker phone
doesn't work but everything else makes this a steal.

Curious about the Galaxy
Player, can it be used as a handset, or is it
speakerphone only or bluetooth required?
Regarding iPhone apps, we tried Acrobits SIP
and Acrobits Groundwire (a few more biz features
such as transferring), both are polished apps
and worked very well. As Tony pointed out,
battery life suffers (figure on less than a
day's charge), and your quality experience will
rely strongly on your wifi deployment. The
ability to have a device that allows you to work
with business apps as well as communication
(email, voice, txt) is priceless, but in the end
we did not deploy this type of technology due to
our high noise environment, large glass in a
fairly tough environment, and the need to have
devices with battery life that could extend
beyond two shifts (16 hours).
We chose the KIRK line because of excellent
battery life, excellent (almost scary) signal
penetration in our factory environment, abuse
survivability, and the ability to send targeted
alerts to the phones (maintenance alerts, etc)
with the 6000 server and 6020 phones, which
replaced lost functionality that the iOS/Android
platform would have delivered primarily.
Your scenario seems to be different, and the
iOS/Android choice may be a truly tenable
solution, given the deployment of a high quality
wifi environment.

In your case I would test coverage with
"any" app, besides counterpath, you can try
the free 3cx (Android and iOS) app and
others. The biggest thing you will find with
wifi -- battery life/talktime (especially
when received wifi signals are weak), don't
hold up nearly as long as DECT. So your wifi
deployment, coverage has a lot to do with
battery life and talktime.

Hi Tony,
We are looking at outdoor
coverage but with a lot of trees
and vegetation.
Considering your response
it shows that things have
changed in recent years too…
We do also have large wifi
coverage already and are
constantly increasing it. In the
past it seemed that wifi was
considered universally terrible.
Has that changed?
And are there any good
smartphone apps? I guess it
would be Android rather than
iPhone since it is possible to
get reasonable Android handsets
cheaply on prepaid plans and
then don't use the cellular side
at all. But for those of us with
existing iPhones is there any
recommended apps?

You need to explain
what kind of coverage
you need and what kind
of wireless
infrastructure you have
(if any).
Snom makes a dect phone
which also has wireless
repeaters and should
work fine. The battery
life and talk time is
very good and does not
interfere with wifi at
all.
If you have a wifi
infrastructure you could
opt for an app on a
smartphone.

Hi
all,
Just a query to
see what the
current thoughts
are on cordless
phones.
We probably
need 2-3 phones
fairly soon that
can transfer
calls. It would be
nice (but not
immediately
required) to have
the phones capable
of switching
between multiple
base stations due
to the physical
area to be
covered. Of course
this adds a lot to
the price so may
be judged to be
uneconomical.
I know this has
been asked before
but a lot can
change with VoIP
phones.
