Can you help?


i have a asterisk setup with 5 BT101’s.

the users complained that when a call comes in and ‘receptionist’ attempts a transfer she gets message person at extension bla bla bla is unavailable.

Although users claim they never switched it on… I asked them to type *79 to turn it off.

Hey presto… it was fixed - for a while.

Anyone know why the phones make themselves unavailable after a while?


When stations started doing that to me, I decided it would be a good idea to give them all static IP addresses.

The local DHCP server was giving out new addresses to the phones, and any calls that happend in the time period between when the DHCP address change happened, and the SIP registration renewal happened, were failing.

After static IP’s, everything stopped.
