Hi,
I have a weird situation in which I just cannot pinpoint the problem I have a two server HA sipx cluster. When I take down the primary server, everything still works with the secondary server but it takes much longer to establish a call (any call). On the primary server it normally takes 1-2 seconds between placing a call and start of the ringing tone. No matter what the endpoint device is. In the failover mode I get much higher times: X-Lite – 5-7 seconds Yealink – 5-7 seconds (just want to mention that Yealink now works great with sipx. In newest revision they fully support DNS SRV records and all the relevant options) Snom – 37 seconds These are constant, repeatable times. Servers are configured with strict failover, not load balancing. We took couple of different approaches with DNS and DHCP to make sure they are fine. We tried two different approaches with the NTP servers. First: manually setting the time for both NTP servers. Two: NTP on the primary sipx has an external source, and NTP on the secondary server is synchronized with the NTP on the primary sipx. The results are the same… When I scan the calls I can see the delay is caused by the secondary SipX, not some other entity on the network. Regards, -- Irena Dolovčak
