Just following up to my own post.

After asking around online I found someone who had a copy of the 4600 series R2.9_2 firmware files that Avaya had removed from their FTP server.

I put the files and upgrade scripts on my HTTP server and after using MUTE - S - I - G - Hash command code to select SIP protocol the phones re-flashed themselves with the SIP firmware. (2.2.2 on the 4602SW and 2.2.3 on the 4602SW+)
