Explain phone firmwares

[Syed]

Dear All,

Can you explain phone firmware coding, please.

Example: SIP75.9-3-1-1S

What does 1S mean in the above example?

Likewise there are a lot of firmware version out there would like to understand the terminology.

Any document will help.

Thanks in advance

Regards,

Syed

Hi Syed,

Firmware Naming Convention

These conventions are used in naming the IP Phone firmware:

SCCP firmware: P003xxyyzzww.bin: where x represents the major version, y represents the major subversion, z represents the maintenance version, and w represents the maintenance subversion.

SIP firmware: P0S3-xx-y-zz: where x represents the major version, y represents the minor version, and z represents the subversions.

MGCP firmware: P0M3-xx-y-zz: where M is the third character. The major, minor, and subversions for MGCP are consistent with the SIP naming convention

For Java-based IP phones, the following naming conventions are used for image files.

SCCP firmware: TERMnn.xx-y-z-ww or SCCPnn.xx-y-zz-ww: where n represents the phone type, x represents the major version, y represents the major subversion, z represents the maintenance version, and w represents the maintenance subversion.
