Questions about T46G Upgrade from 28.72.0.1 to 28.73.0.50 - mwoffenden - 04-21-2015 02:03 AM


  1. May I upgrade the phone directly from 28.72.0.1 to 28.73.0.50?
  2. When I upgrade the firmware, does this also do a factory reset?
  3. My VOIP provider has a much older version (28.72.0.1) on their server, will their provisioning work with 28.73.0.50?
  4. I've saved my custom configuration (in a .bin file), may I apply that to the phone after the firmware upgrade?

Hi,

1. Yes, you can.
2. No, phone won't do a factory reset. All configuration will be saved.
3. The provision mechnism is same to V72 and V73.
4. A configuration file in V72 can't be imported to phone runing in V73 since the config.bin file is encrypted in V73. But you custom cofiguration won't be cleared in upgrading.

Regards,
James
