hosted Posted December 9, 2012 Report Share Posted December 9, 2012 I have snomone regestering to a DNS (sip.registerme.com for example) THE DNS has A and SRV records. I change the A and SRV records to a new server. the oubound calls start slowing to the new server, as they should. BUT the registeration never updates to the new server.

Vodia PBX Posted December 9, 2012 Report Share Posted December 9, 2012 Well, the RFC DNS idea was that the clients always look up the DNS records. The problem is that the overall uptime now depends on the stability of the SIP server AND of the DNS server. We also had numerous discussions on this forum why the SIP trunks go down from time to time when service providers choose TTL of 60 seconds for their entries... Anyway, I depends on the vendor. Our strategy is to use DNS for the provisioning, but then use IP for the outbound proxy. This way, if the service provider really has to move the service from one server to another, a re-provisioning of the phone will be sufficient--and we don't have to worry about DNS problems with the handsets.

hosted Posted December 10, 2012 Author Report Share Posted December 10, 2012 I am talking about the trunks. you should make it to where at least if the trunk registration fails (ISP took down the switch) it would re-qwery the DNS and hopefully get an update to register to a new IP.

Vodia PBX Posted December 11, 2012 Report Share Posted December 11, 2012 As long as the registrar returns 2xx the PBX stays with the address. Only when the registration fails, it goes through the whole algorithm with DNS & everything. AFAIK that's the way it is today (5.0). Quote Link to comment Share on other sites More sharing options...
