We have a really strange problem at a client site with the wireless install.
We have installed 2 EOC2611P devices so an office across the street (300FT) away can access the network and use their IP phones. Computers can access the local network fine, their Cisco IP phones however will not register to the Call Manager system.
We have no idea why the phones will not register to the Network. Engenius support thinks itís a problem with the Cisco IP phones. We had his Cisco Phone support guy involved for over an hour until we learned that the phones lose their ability to connect when the Engenius device is active.
We have a good usable signal, we are able to communicate with the network at the main office and even to the office in Peoria, IL as well as the internet but the phones will not registerÖ.
We had a ping setup to watch communication between the two Engenius devices as well as the IP phone locally, while we were on DHCP and while we had static IPís set. While communication is good to the main office we could not communicate with the phones, as soon as we unplug the engenius device and lose connection to the main office (within seconds) the ping to the phones locally begin to work properly, as soon as we connect the bridge and regain communication to the main office, we lose the phones.
I tried every setting option available on the engenius device, with no effect. We even had Engensius support on the phone for an hour to verify the settings.
We tried every option in both AP to Bridge mode and WDS Bridge to WDS Bridge. We can get a good connection to the network via PC but the Cisco Phones will not register to the Call Manager 7 system in the main office. Again we tried this with DHCP and Static address. The Phones are able to obtain an IP address but they will not register to the system.
