Cordless phones over your wireless network

I work in a manufacturing plant that uses cordless phones to
communicate. These are older models that are not made anymore and all
testing to date shows nothing is able to replace the range inside these
steel walled buildings.

Question- Our facility has wireless access points all over the place
for wireless networking of our computer equipment. Is there a phone or
phone system that can communicate directly with these access points,
the signal go to the router, and somehow extracted/converted to go to
our Avaya Definity switch?

You should contact your vendor and visit:
http://www.avaya.com/

The short answer appears to be yes, they do have a solution for you. But
contact your Avaya vendor for specifics of what you desire and what they
can deliver. But based on the website they do indeed handle telephone over
TCP/IP.

fundamentalism, fundamentally wrong.

You could go the Avaya route:
What is the difference between IP Telephony and VoIP?

http://www.avaya.com/gcm/master-usa/...ptelephony.htm
but that seems to be proprietary.

If maintaining the existing switch is a requirement, then you're stuck
with their scheme and products. Reading between the acronyms, it
appears to be an ordinary SIP phone. You might wanna just try an
802.11 SIP phone and see if it can be configured and used.

However, if you get a non-proprietary phone system, such as those that
are Asterisk based:
http://www.asterisk.org
and use anyone's wireless VoIP phones such as the almost just
released:

you're not stuck with a proprietary solution.

Hi Jeff,

Bottom line is I got a quote from AVAYA at $14K. Although I am sure it
would work great it seemed high and also appeared to be recreating a
wireless network that we already have installed for data. It would be
almost impossible to justify the cost.

My thinking is this. We currently have standard cordless analog
phones. they are connected to the switch on analog ports. My thought
was that if we had a phone that could be picked up and understood by
our wireless access points we could bring the signal out at the router
(somehow) and send this to these analog ports.

I got the idea from looking at my VOIP phone at home. If I had a
cordless phone that could communicate to my wireless router, the VOIP
adapter is on one of it's ports. The output of this adapter is plugged
in to my wall phone jack. Couldn't this output just plug in to my
analog ports on my PBX switch?

This stuff may be second nature to all of you. I just am new to it.
Are there phones out there designed to communicate through an existing
wireless network?

Jeff,

I tried your last link and it did not go anywhere for me. I don't think
I want or need anything proprietary.

I don't quite understand the asterisk based link. Just what is it?

Ouch. However, commodity VoIP phones are currently $200-$250/ea.
That's still fairly expensive.

If the Avaya wireless also works on 2.4Ghz, you will have an
interfernce problem with your existing network.

Yeah, but that's not taking advantage of digital audio (VoIP). Once
you have a digital version of the audio, there's no sane reason to
convert it back to analog until it his the caller at the other end.
For example, the Asterisk based switch never converts anything to
analog. It goes via a T1 to some IP telephony gateway service
provider which dumps it into the PSTN (public switched telephone
network). Think digital, not analog.

Again, you're thinking analog. You VoIP phone at home is digital all
the way to Vonage or whomever you're using. You could plug an analog
cordless phone into it's phone jack. You could also eliminate the
VoIP box completely and have it in the VoIP 802.11 phone. That's what
I think you need or want. The benifit is that it uses your existing
IP network.

>The output of this adapter is plugged

Yes, but as I previously mumbled, it's silly to do that. Go digital
all the way to the PSTN.

>This stuff may be second nature to all of you. I just am new to it.

Actually no. Wireless VoIP is a new technology with new products and
proposed standards just coming out. I expect it to be popular because
people can use them to make free phone calls via public Wi-Fi hot
spots and not pay the cellular providers. You would be doing the same
thing, except you already have a Wi-Fi network on which it runs.

I assure you that my link is not proprietary. It probably wrapped in
your news reader. Try again, it works.

>I don't quite understand the asterisk based link. Just what is it?

Did you read through the web pile and follow the links? It's an open
source IP telephony switch intended to replace or suppliment your
existing Avaya switch. Methinks you should read about the basics of
IP telephony before you start asking for quotations. It's not easy.

http://multitech.com/ makes some POTS->VOIP and VOIP->POTS boxes, if
you just want to use your network for phone transport...
