It hasn't been introduced into most product lines for the same reason any other feature hasn't been implemented in a vendor's system - lack of financial motivation. These guys build for their biggest (volume and $$) customers and their needs, so obviously companies like Acme, BroadSoft, Sonus, Polycom, Aastra, Adtran, etc are simply not seeing a business need to take the time to develop IPv6 into their products yet. Among IPv6's strongest supporters have been the open source community (look how long the Linux kernel has had basic v6 support), so I'm not surprised at all that projects like Freeswitch or OpenSER (and its various names) have taken the small step to add support for the addressing. Basically I think you'll see IPv6 support in these types of commercial voice products only when there becomes a drive for it from their large carrier customers. The large carriers have however been the slowest to try new technologies in the VOIP realm, so v6 I'm sure is still way down the line. -Scott From: voiceops-bounces at voiceops.org [mailto:voiceops-bounces at voiceops.org] On Behalf Of Craig Askings Sent: Monday, October 26, 2009 7:25 PM To: VoiceOps Subject: Re: [VoiceOps] IPV6 2009/10/27 Jeff McAdams <jeffm at iglou.com> SBC support This was part of the whole point of the thread. Why hasn't the voice industry adopted IPv6 more aggressively? I was including the SBC (and other gear and software) vendors in the voice industry there. Yes, this is probably the only real obstacle you presented that would prevent voice operators (admittedly the focus of this list) from really deploying IPv6 aggressively, but I will say that my commentary was commentary about the overall industry, including the gear and software vendors. Freeswitch supports SIP over IPv6 in it's main production code base, it isn't a separate set of patches like asterisk's current v6 support. -- Craig Askings Network Engineer | Over the Wire Pty Ltd craig at overthewire.com.au | www.overthewire.com.au Phone: 07 3847 9292 | Fax: 07 3847 9696 | Mobile: 0404 019 365
