Most of my hands on time with hardware SIP phones has been with Polycom's, and Cisco SPA 525G2's, and one of the killer features for me is that if you've got an FTP server and understand how to correctly configure the Polycom SPIP's you can get them to backup any changes users make to them to config files on the FTP server. I loved doing this, I could swap out phones and have all settings carry over, and users had the confidence that they'd never lose any changes they made. Now the downside is that Polycom SPIP's do not support STUN, the Cisco SPA 525G2 does but can't do the backup config/FTP trick that the Polycom's can. So, is anyone here aware of a SIP hardphone that gives me the FTP backup and config features of a Polycom but with STUN ?. Thanks.
