# Script checks if CUCM has assigned IP address 10.79.1.8.  If the IP address is detected, the script suggests to change extension range, SNMP configuration and 
# IPv4 address in CUCM database. Then the script changes IPv4 address and default gw in OS according to the BT number and reboots CUCM.
# If no IP address 10.79.1.8 is detected, it skips IPv4 configuration and continue with changing NTP and DNS server. Hostname must be changed manually from 
# CUCM CLI and let CUCM to reboot. The script continues with IPv6 address configuration, delete logs and reboots CUCM again.
