Hi, as in China, we are allowed only wireless IP phones (No DECT). so we planned to install Siemens PABX+Aerohive AP+GreenU wifi ip phones. anyone have experience it? or you have any other phone system which is running good with Aerohive wireless technologies? our main point is to deploy good running wireless IP phones in China factory. thank you in advance.

Hi Steward,

I haven`t got Green-U experience myself but a good operational VoWifi deployement depends on a lot more then just the Phones.

What you need to make sure of is that you enable QOS on the 4 elements you are using. PABX -- Switches-- AP`s -- Phones.

Next to that design your network properly to actually enable your phones to connect without to much interference and ensure good quality.

If possible ( and the phones support it) deploy Vowifi on the 5Ghz rather then 2.4Ghz. There are a bunch of Feature sets that makes life easier build into the product.

We have experience with Vowif so we should defenitly be able to guide and Help you create a stable environment.

Regards,

Roy

really appreciate to get this info... i tried to get info from many media/channels but up to know, i only get information that it is will work but i need a case study or reference from existing user.

Hi Roy,

we have new building in Wuxi New District in China. In China, not possible to have DECT phones as we are having now.. so we have to choose only wireless IP phones...

We have a company using Cisco VoWiFi phones using Aerohive AP330 access points running HiveOS 5.1r5 without an issue.

From a wireless point of view:

1. Ensure that the voice traffic is being correctly identified and QoS tagged.

You can check the QoS tagging using the following procedure:

* SSH into the access point the VoWiFi phone is going to associate to
* Associate the VoWiFi phone to the access point
* Execute a "clear qos counter" command
* Initiate a call with the VoWiFi phone
* Execute a "show qos counter user " command

You will now see the user profile and MAC address of the VoWiFi phone as well as traffic statistics, including the QoS class, from the VoWiFi phone.

2. Ensure the classifier map (Configuration -> Advanced Configuration -> QoS Policies -> Classifier Maps) is correctly configured and assigned to the appropriate network policy.

3. Ensure the marker map (Configuration -> Advanced Configuration -> QoS Policies -> Marker Maps) is correctly configured and assigned to the appropriate network policy. If you are not configuring the LAN equipment you will need to check with the engineers who are that the DiffServe code points, for example, match with their configuration.

4. Ensure the radio transmit power on the access points is not too high. If the VoWiFi phone is associating using the 2.4 GHz spectrum I have found that 20 dBm is too high and the VoWiFi phone will not roam correctly causing user experience issues.

5. If you can,utilise the 5 GHz spectrum for the VoWiFi phone but make sure in your active site survey that the 5 GHz retry rates do not go higher than 2-3%.

Has anyone successfully connected an Avaya 3641 Wireless IP Phone to an AP230 access point? It is set for open authentication with MAC filtering for the phone. I am able to connect the Avaya 3641 to a BR100 using the same radio profile.
