AW: [Sip-implementors] implications of multiple registrars

[Christian Stredicke]

What we did was replicating the registrations to the other servers using proprietary extensions. I am clueless its that’s according to any standard but as usually a server farm will consist only of one vendor registrars I don’t thing it’s a big deal. Maybe someone is interested in a draft about this.   Security & Co can be handled with the standard SIP toolset.   Example message:   X-SNOM-REPLICATE sip:192.168.0.44 SIP/2.0 Via: SIP/2.0/UDP 192.168.0.22:5060;branch=z9hG4bK-q01sdzszu4pp From: <sip:192.168.0.22:5060>;tag=1 To: <sip:192.168.0.44> Contact: <sip:192.168.0.22:5060> CSeq: 1206 X-SNOM-REPLICATE Call-ID: [EMAIL PROTECTED] Content-Length: 231 Content-Type: text/xml <?xml version="1.0" ?> <registration> <user>jh</user> <host>intern.snom.de</host> <call-id>[EMAIL PROTECTED]</call-id> <expires>0</expires> </registration>       -- Dr.-Ing.

All the SIP UAs in abc.com domain send registration to a proxy, which forwards them to one of the registrars and thus tries for laod sharing.   Do you foresee any adverse implications of having more than one registrars for a domain?   thanks, = Kedar =
