Description (partial)

ATA 190 fails to register to CUCM
PCAP off ATA 190 will show a DNS query (after it downloads TFTP CNF file), for the wrong FQDN.

CUCM has to be configured by hostname
DHCP server has to have domain/dns configured.

The ATA will send the DNS query out to the hostname configured in CUCM + the domain it receives from DHCP.
