Nice! Thanks for the detailed history. From: VoiceOps [mailto:voiceops-bounces at voiceops.org] On Behalf Of Michael Bain Sent: Monday, April 13, 2015 4:57 PM To: voiceops at voiceops.org Subject: Re: [VoiceOps] Never seen this on a Polycom The 0004f2 prefix came from Circa Communications Ltd when Polycom bought them for their IP phone product and founded the SoundPoint IP line around it. At that point the SoundStation IP3000 was already a product (and I think it used 00e075, but not sure), and the IP4000 was already in development. For the first few production runs the IP4000 used the 00e075 prefix. Eventually both the SoundPoint IP and SoundStation IP products were unified on the 0004f2 prefix.

I?ve seen thousands of these things deployed, I can?t believe I never ran into this before . . . anyone else seen this?
