After a recent power outage I found our VVX300's did not auto-reconnect to the PBX after power had been restored. In this case the DNS server was powered up after the phones but I had no problems with our IP 335's. A reboot took care of it but that is unusual behavior for a network device and really should not be the case.
Are there some settings I can change to ensure the VVX300's continue attempting to reconnect until they are successful?
It is always useful to include the currently used software version as issues experienced may already be addressed in a newer release.
This also allows yourself and others to check against current software release notes.
The above is also stated in the "Read First: Welcome to the Polycom VoIP Forum"
