I bought two Nortel 1535 phones from ebay, I should share my own experience vs your experience with the list here
e. Sound quality is crap Compared to Polycom/Aastra/Snom phones I have, its quality is the same level as Aastra phone f. Managed to get it working over a LAN exclusively. I have one phone working via Wireless, one phone with wired LAN, I didn't test with any SIP servers outside my LAN, but lots of users do g. No video / H264 or H263 in the LAN with Asterisk. I have one phone registered with my Asterisk, one phone registered with my FreeSWITCH, none of them is Nortel or SipX platform, the video calls using H264 and H263 with Asterisk/FreeSWITCH or mix all working very well.
