Phones doesn't follow SIP server IP changes.
When using a hostname for the SIP Server the phone will not move to another server if the IP for that host changes. If my server is abc.com and I change the DNS for this from to it will stay connected to the first one without ever changing. This seems to be happening across multiple models of Yealink. My Cisco/Linksys, Grandstream, and others seem to follow the DNS changes fine. The DNS is set to refresh every 90 seconds and I have given the phone 24 hours and it is still connected to the first server. We do not use the failover sip server setting as we have multiple locations and depending on the situation we control it through the hostname resolution to move phones to the most available server. Any idea why it sticks to one server?
