Subject: Updating firmware on SIP-T22P and SIP-T28P

Hi folks, I inherited a batch of about 450 Yealink phones SIP-T22P and SIP-T28P.
I would like to get a manual/procedure to batch update firmware of these phones the most automated way possible.
The phones have this firmware:
SIP-T22P firmware 7.60.0.120
SIP-T28P firmware 2.60.0.140

i would like to also switch the language to spanish.

Thanks for your help on this...

have a great day.

Hi Erick,

You can achieve it by autoprovision. These are brief steps:

1. Set up a provision server(HTTP/TFTP/FTP/HTTPS)
2. Place the firmware you want to upgrade to in the server.
2. Edit a configuration file, place a firmware upgrade parameter and language parameter into this file.
3. Place the file in provision server.
4. Write the URL of this provision server into a DHCP option(43 or 66).
5. When phone reboot, it will get provision server address from the DHCP server, then go to fetch configuration and apply it.
6. Phone will upgrade and change language.

For more information please read our autoprovision guide:
