# 7940 - 7960 Series :
|
|
## Intro :
|
|
|
|
You will need an IPv4 Network with :
|
|
* DHCP server (tested on tagged Voice-Vlan)
|
|
* TFTP server (option 66 configured in DHCP server)
|
|
* physical access to the phone
|
|
|
|
## Factory reset sequence :
|
|
When the phone start's up, (either POE or local adapter), dial the `#` until the screen starts up.
|
|
When the screen tell's factory reset sequence, Dial `1 2 3 4 5 6 7 8 9 * 0 #` in that order. Phone will ask you if you want to save his network config.
|
|
Dial 2 (network config erase).
|
|
|
|
## Flashing process :
|
|
After factory reset, the phone will look up in the TFTP server for his own config file (`SEP<mac-address>.cnf.xml`)
|
|
In the case of flashing to SIP firmware, that file has to contain the fact that it goes to SIP and a firmware version.
|
|
All system files must be stored at the root of the TFTP server.
|
|
|
|
## SIP phone provisioning :
|
|
After the SIP firmware has been flashed, the phone will start to TFTP try `SIPDefault.cnf`.
|
|
`SIPDefault.cnf` is the file that contain's SIP options that will be used across all phones that can access that file.
|
|
(like NTP server's, time format etc.) so that the specific SIP file can be smaller (not that usefull on a modern server with 3 phones in the system. kind of a big deal on a big phone system on a small CME router)
|
|
|
|
Either `SIPDefault.cnf` gets found and the phone will load the options, either it's not and the phone jumps to the next file. `SIP<mac-address>.cnf`
|
|
|
|
That file contains the phone specific options. If some options were present in `SIPDefault.cnf`, they will be overwritten on the local phone.
|
|
|
|
## Startup Sequence :
|
|
At every reboot, the phone will look up for the ``SEP<mac-address>.cnf.xml`` to see what firmware is needed. Then `SIPDefault.cnf` and then `SIP<mac-address>.cnf`. |
