Firmware update on IP550

I have read countless articles, many with broken links since the version is so old, and getting no where.


I am trying to upgrade from to 4.0.15


Is it possible to use a locally setup FTP and upload that way? If so, do I just need the 2345-12500-001.sip.ld file in the directory? Does TFTP need to be used?


Can this be done from the webUI or just the phone itself?

Re: Firmware update on IP550

You can use a local FTP Server to update your phone to the latest firmware.

You can use that site as a guide on how to update your Soundpoint IP 550 phone to the 4.0.15 firmware. Before you can upgrade you will need to upgrade the bootrom of the phone which that site provides working links which I have provided below and verified both links are working.


or if you have a SoundStation 6000/7000, you need the B version here
