I have IP 7940 phones connected to an IP PBX. After the IP-PBX configuration was done, i plugged in the 7940 phone to get it on track, but unfortunately it didn't work. Now i see on the ip phone screen "TFTP timeout" and all the buttons are kind of frozen. So i tried to reset it to the default conifguration by rebooting and hold down on "#"..., and it didn't work too.
Basically the phone is not working at all, and i'm a little bit concerned and i don't know how to make work///
Is the IP-pbx - callmanager ? or are you running SIP on the phone and using a third party call agent to register the phone ? Is the phone setup for dhcp ? if yes, make sure you have a Dhcp option 150 setup on your dhcp server so that phone can download the config/firmware from callmanager. the option 150 should be the ip address of the callmanager that is running the tftp service.
You can disable dhcp and set static settings on the phone.
a. Choose settings->
b. network configuration ->
c. type **# (settings will unlock)
d. go to option 33, erase configs do not press save.
e. go to dhcp -> set to disable
f. go to option 8 -> use edit softkey to edit ip address.
g. similarly edit options for subnet mask, default gateway and tftp address.
h. hit the save soft key
i. if phone doesnt reboot properly, try **#** to reset the phone.
I have IP-PBX - Callmanager, and the phones are not setup for dhcp. It's a static ip.
I couldn't reset the phone by trying **#**. All the keys are frozen. I did the instruction you had in you answer and when i plugged the phone, it said on the screen "tftp timeout" and since then the phone is not working and cannot be reset.
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
