WIFI 3720 Phones Basic Question 2

[ega218]

Hello,

I currently have an IP500 running R5.0.15

I have been asked to setup a wireless phone that could be reachable through out our entire building. Our building is very long and the 3810 wireless phone does not have the range to satisfy this need.

So I am looking at installing one of the new DECT 3720 or 3725 IP phones.

I have a basic pre-install question. I currently have several cisco 1242G WAP units through out the office. Is it possible to use this Access Points to connect the 3720 or 3725 IP phones or do I have to use an IP-DECT Base station.

If not could I still use the 3810 and place a base at different areas to allow for the 3810 to have coverage at various areas.

Thanks in advance for your comments.

If not I wounder if the 3920 is supported with R5.0 or R6.0.

The 3720 or 3725 is a dect phone and not wifi!
The 3920 is not supported on the ipoffice.
You could go for the ipdect R4 compact instead of the normal ipdect R4

The compact dect has 4 channels instead of 8 channels and is much cheaper.


I personally do not like wifi phones, too much hassle

Thank you tlpeter for your suggestion. Is the ipdect r4 compact supported with R5.0 or only R6.0?

 

[intrigrant]

Both, it may be cheaper to buy a 3645 WiFi phone.
With the latest firmware it can be used over a Wifi network without the need of a AVPP unit.
Be carefull though, the WiFi network must be set-up in a specific manner otherwise roaming will not work.

 

[tlpeter]

The ipdect compact works on 5.018 too
Intrigrant, isn't the 3631 the one who works without an AVPP ?

Hello Intrigrant,

I think I will go with the 3641 WiFi phone solution. It will be cheaper and I will be able to use existing hardware and wiring.

Do you know where I can get the "specific" information on the required setup for the phones to roam using our existing Cisco 1242 WAP.

If it is just what is located in Avaya, no problem I will review. However, I just want to make sure that there is not any other special requirement when using with R5.0.15

Thanks again

WiFi phones will make your life hard and the customer will hate the performace and battery life.

if you are serious about portable phones in a commecial sense, then spend the money on a DECT solution

Wireless is a bit of a black art, and if you want it to work properly you need to do a wireless survey.

all the wireless and DECT products are in the KB. Look it up

 

[ega218]

If the problem is with the WiFi coverage then I should be OK since we have four Cisco WAP units installed with good overlap between all of them. All of our laptops have no problem at all at any part of the building getting a strong WiFi signal.

Now if you are telling me that regardless of the signal, I will still have headaches with troubeshooting these units, then it sounds like in the long run the WiFI 3641/45 units will actually be more expensive with all of the time I will spend supporting them.

 

[intrigrant]

The problem with WiFi & handover is not coverage but is the channel allocation.
Each base station may only transmit on one channel and the overlapping basestations must be two channels apart.
If you can set up with these rules you'll be fine with WiFi.
Searcg the spectralink site for a site survey doc.

Does anyone know if I used the 3641 IP Phone, will I need an AVPP with IP500 R.5.0.18?

Also, could I just purchase the Ploycom 8020 phone or do I have to purchase the Avaya 3641 model. I believe that they are both the same, but not user if the Avaya model comes with different firmware.

Thanks.

my suggestion... skip dect. skip wifi.

Go with EnGenius analog. 250,000 square feet or through 12 floors of concrete it works. Battery life great, built extremely tough, no network hassles or site surveys or expensive dect phones/multiple base stations, licensing crap...

Welcom to the 21st century and buy an analog phone which can do ??????








Nothing!!!

Go for the ipdect compact if you need a couple of phones

Ideally I would prefer to use our existing Cisco Wireless Access Point units which we have in all of our offices already. Then there no more wiring involved.

Not convinced on using the EnGenius products, as I have not seen great reviews on the long term quality for these units. Besides, having a phone that will access all functionalities of the IP office would be my best option.

However, I still would like to know if I will need an AVPP if using the 3641/45 with an IP500 R.5.0.15.

Thanks.

 

[tlpeter]

Yes you do, only the 3631 does not need one but is not supported on the ipo and does not have all functionality.
That is common with wifi phones.
If you want more functionality then you need dect.

A AVVP 10 costs $ 499,00 a 3645 WiFi phone costs $ 675,00

A DECT solution costs:
3725 handset $380,00
license $40,00
per basestation $1.400,00 or $849,00 for a comapact basestation ( R6.0, max 5 allowed )

As you will need several basestations to cover the building for just one phone i would go for the wiFi phone and reconfigure the WiFi access points.
That is far out the cheapest solution.

If you do not really need the IP Office features on the phone then consider a commercial WiFi phone and a SIP license on IP Office, the phone will have basic call setup, transfer etc. and name/numer display.
For most users that will just do.

look here for example :

[ega218]

Thank you intrigrant. These phones will be needed for warehouse & service floor personnel which will not need the full functionality of normal Avaya phones. Therefore, for value I believe the commercial WiFi and SIP license soution may be my best option. Especially since I already have several SIP licenses with my current setup.

The DECT solution is definitely cost prohibitive for the number of phones I need.

Again, thanks your informative post.

 

[intrigrant]

Another option : if the phones are not used a lot then consider mobile twinning GSM phones.
Buy some mobile user licenses, create users for them and twin the GSM with the internal number.
No hardware required and the users can transfer calls from their GSM if you have a ipo500 with ipo500 ISDN or SIP lines.

 

[ega218]

I actually have the mobile licenses and have tested the twinning features. For some reason, even though I enter to twin from the very first ring, it take 2-3 rings before it reaches the Twin GSM phone.

Also, since some of the GSM phones (actually they are not GSM, but just mobile cellular phones) do not have unlimited incoming calls, it would take away from their minutes and a couple of the phones will be used a lot.

Thanks for the idea though.

 

[ega218]

Does anyone know if I need a license if I purchase an AVPP and use a 3641 phone, and an IP500 on R5.0.15

Thank you.
