I have a 2800 SRST gateway on a tug, yes a tug. When at the jetty the 2800 router connects to my network over a wireless bridge and phones register with the callmanager on the "land" network.
When the wireless bridge is un-plugged from the router or powered down the phones register with the router and can make calls between handsets on the tug.
However if the tug goes out of wireless range the phones continue to try and register with the call manager. The only way to get them to register with the router is to power down or un plug the wireless bridge.
Any suggestions would be most welcome.
