We've been flashing J169 model phones H.323 for several years. They come out of the box flashed SIP and we then flash them h.323 and then deploy. There are PSN's about the version of SIP having to be a certain revision to be able to flash them H.323. We've accounted for these situations. However, we recently got a different J169 model, which says J169D20A. Flashing to H.323 fails. We are able to get into the menu and change the signaling like normal, but upon reboot they say software download failed. It's only happening on this specific J169 model. We've tried upgrading the SIP FW and even downgrading it and the H.323 flashing fails. The Avaya PSN lists the following models:
