[bcab] Re: FW: IP Telephony

I recently set up a Siemens Gigaset for someone who is totally blind however 
they didn't have any 
serious tactile limitations.  Ligo Electronics do quite a wide range of VoIP 
phones which I did look 
at at the time, in particular the Aastra and Doro brands, seem to have very 
tactile buttons & good 
features.  They are not cheap though!  See

The answer re: the magnification causing reduction in quality of the images on 
the softphone, may be 
to try lowering the video resolution and perhaps even use a larger monitor if 
possible. 
Unfortunately most softphone software does use textured bitmap graphics, which 
tend to produce this 
effect under high mag levels.

Hi

I don't know if you will be able to help, but I am struggling to fulfil a
request by a partially-sighted member of staff for a large button phone that
will work with our VOIP system, and have all the functionality offered by
the phone system.

The user has extremely limited vision, and currently uses a BT Big Button
phone, but this does not give him the ability to transfer calls etc. We have
a Cisco system, and all of the IP phones available have very small buttons,
and functionality based on a small electronic display that he cannot see. We
have tried installing a softphone (Cisco IP Communicator), but this does not
work very well with Zoomtext (14x magnification), as the image is grainy and
unclear when magnified, and by the time he has navigated around the screen
to dial the number the call has timed out.

The user has asked for a larger phone terminal than the BT phone, but I
cannot find one any larger, and this would still not give the full range of
functionality on the VOIP system.  Can you suggest anything currently
available that may be suitable, or any modifications we could make on the
existing system that might improve matters? The only other thing I have
found that might work is a device from the US called Teletalk made by
Compusult, do you know if any UK organisations have had success with this
product?

He is registered blind, his sight is deteriorating, and so although I am
looking at solutions for a partially-sighted user I am thinking it may be
better to look for something that would suit someone with no sight. He also
has diabetes so anything based on touch is no good, am thinking of
speech-based solutions if there are any?
