WiFi VoIP Phone Doesn't Respond to PING Unless Searching the Connected Network

I have an INCOM ICW-1000G WiFi phone and am having difficulty receiving calls, although I can call out all of the time. The WiFi signal is very strong and as far as I can see from the phone's display it is not loosing connection to the network. However if I PING it from a connected workstation then the phone will not respond until I perform a network search from the phone itself. All other times PING command returns timed out. The response to the PING is immediate as soon as the search begins. Afterwards it returns back to times out. If I start to dial-out from the phone then again I can see from the workstation that it begins to respond to the PING command. After the call is hung up it will revert back to times out.

Since I am having difficulty receiving calls but not when dialling out then I am making the assumption that the observation above is related.

Any ideas what could be causing this?

Thanks, Gary

Sounds like the phone is going to sleep and waking up when it receives an ARP broadcast.

Try turning off power-save mode on the phone - use constantly a awake mode instead.

Hi, Sorry this is a very late reply to an old post but recently joined EE. The initial version of the ICW-1000G had a bug that prevented connection using some variations of (If I remember correctly) WPA2. The latest version of firmware, 1.0.7 was released in Nov. 2015 and corrects this error and adds news features like 722 support. You can always get the latest firmware at our website, sometimes before Incom posts it on theirs. The manuals, Firmware release notes (which show a complete history of FW versions and their fixes) and other information can also be found at http://allstarnetworks.com/icw1000.htm.
