Problem:Â Lately, I have been having problems with my Shoretel 115 and 230 phones. Â When I plug them in, they would get an IP address but unable to contact the FTP server so the end result would be “Service Unavailable.” Â Tried manually putting the FTP address by hitting the mute button, typing “setup” and hitting the pound key… Â But that is unacceptable with close to a hundred computers..
Solution: Â Double checked my DHCP server option 156 and at first glance it looked correct “dhcpserver=x.x.x.x” Â But it wasn’t. Â The correct syntax is “dhcpservers=x.x.x.x” Â So be sure that you include the “s” when you create that option…
Update: Â Moved some 115 and 230 phones to a different subnet and about half of my phones got the “no service” error message again. Â I realized that my ShoreGear 50 (SG50) had the wrong default gateway and that is why my new phones wouldn’t connect. Â I changed the gateway to the correct number and all was well.
