I recently purchased a Linksys WIP 330, Dlink DPH-540 and a ZyXel Prestige 2000w WiFi VoIP Phones.
On my network, I only have the above 3 devices and my laptop configured via wireless. Nothing else is on this network.
When I perfomed a ping from my laptop to any of the 3 phones, I have a response time which fluctuates from 50ms to 200 ms.
I also tried turning off two of the WiFi VoIP phones, performed the ping test and the results were the same.
When I connect my Asterisk server to this network and pinged my laptop, I have a response time of less than 1 ms.
Strange enough, I performed a continuous ping from the latop for both the Linksys and Dlink phones. When I called from one phone to the other phone, the response time for both phones dropped to 3 ms however I hear alot of echo.
Is this a normal behavior for WiFI VoIP Phones?
