What is .SBN file?
Firmware file, or "image" file, used by Cisco IP (Internet Protocol) phones; contains data that controls the operation of the phone; used during the IP phone firmware upgrading process; usually distributed with a few other files in a firmware package.
The data in SBN files usually complies with the SIP (Session Initiation Protocol) IETF (Internet Engineering Task Force) standard. Often SBN files are used when upgrading an IP phone from the Skinny Call Control Protocol (SCCP) to the SIP protocol.
The firmware on Cisco IP phones can be managed using the Unified Communications Manager software, which was previously known as CallManager.
NOTE: Cisco IP phone SBN images are "signed" by Cisco so that the issuing source can be validated and the file cannot be easily tampered with before installing onto the phone. Unsigned images are distributed with the ".bin" extension.
