Overview
4.6.1 introduces support for 3.3 and above firmware. It also removes support for firmwares below 3.1, as well as for phones SPIP 300 and 500. Instead it introduces support for VVX 500 model.

| Note that by multiple versions we understand at most one firmware per major version defined. For instance we will not be able to have 3.2.6 and 3.2.7 versions deployed, since they would both go to tftproot/polycom/3.2.X folder. |
Installing firmwares
The Device files interface for Polycom firmwares has not changed visually, except for adding a new Version field - a combo with "3.1.X", "3.2.X" and "4.0.X" values. An admin should choose the correct version of the firmware installed. By doing that the admin will ensure the firmware will be unpacked in the correct folder.
...
Phones and versions are connected through the phone's Firmware version field. A phone that has "3.2.X" version will look for the SIP application in the tftproot/polycom/3.2.X folder - the [MAC].cfg file is configured to accommodate this. Configuration files are kept in the tftproot folder just like before 4.6.1.
Admins can deploy multiple (major) firmware versions. You can have a 3.1.X, a 3.2.X and a 4.0.X firmware deployed for the situation in which there are multiple phones with different firmware versions.
Installing bootrom
| Note | ||
|---|---|---|

| While not forbidden, it is strongly discouraged to have multiple bootroms deployed. |
To install a bootrom you need to upload and activate the bootrom in any of your Polycom device files or create a separate device file for it. Bootrom files will be unpacked in tftproot folder, and not in a firmware folder (like polycom/3.2.X). The reason for that is that a phone will look only in the root folder for the bootrom.
Upgrade from 4.4
When upgrading from 4.4 admins can leave the device files in place just fine and the system and its defined phones will continue to function just like before. Even when profiles are sent to a phone, although [MAC].cfg will be configured with the new path to the sip.ld file, if the phone will not find it it will just use the existing SIP application.
...
It is recommended that admins take some steps to "upgrade" their Polycom phones to 4.6.1 new system. (Note that by this we don't mean updgrade the phones to a different firmware version/bootrom.)
