Working on a Polycom 330. I have DynamicDNS setup to update the IP of the Asterisk SIP Server in case of a failure.

 

The phone seems to be caching the IP of the DNS on clean (file format) boot and not updating when the record changes.

 

I assume there is a XML entry in the sip area I can change to tell the phone to always lookup the A record when registering.


Can someone assist with that entry? I cannot seem to figure out what the relevenat section/setting is. I only want the phone to register via A record, so any other types (SRV, etc) should be disabled.

 

Thanks
