Probable Cause
Side control defective.

retrieve the
configuration file from
MiVoice Business due
to the missing DNS
server's IP address
(DHCP option 6 not
configured). As a result,
the set is unable to
resolve the FQDN to IP
address when the SIP
server or the

programmed as FQDN.

"DHCP Options" form with
a valid DNS server's IP
address. Ensure that the
server is configured with
MiVoice Business' FQDN
and matching IP address.
