Interesting reply (from Paul & Adam). I expected a reply where the "who is authoritative for the ssp.example.com domain" to play a central role. /Martien -----Original Message----- From: Paul Kyzivat [mailto:pkyzivat@cisco.com] Sent: Tuesday, September 28, 2010 2:45 PM To: Martien Huysmans Cc: martini@ietf.org Subject: Re: [martini] martini-gin-08, question on public-gruu That's how it will work unless the pbx optimizes it. Its not really any different than when one UA of the pbx sends an INVITE to sip:+12145550102@ssp.example.com, which could arise in many ways. The pbx can optimize this by recognizing its own addresses.
