Last Updated 2 years ago

This version of firmware constitutes Cetis’ 3rd generation of SIP phones based upon a new chipset and SIP stack. In addition, we are introducing a set of firmware file name changes with this release. Cetis SIP firmware follows a naming convention based on model. All Cetis IP phones share the same base chipset and firmware. Server registration, SIP messaging, and call control are all the same. The different model prefixed versions are to accommodate variances in single vs. true 2-line capability, corded vs. cordless radio handsets and LCD display screen sizes. and includes numerous enhancements and bug fixes.
