call agent. During this time it will play call progress tone. Then the tone will
change to a dial tone if the DHCP and connection with the call agent is
successful. It will play an error tone if the DHCP or call agent fails.

It means that the information exchange with DHCP or MGCP call agent has

call agents are running. Also, restart the phone to check if the MGCP phone is
configured properly.
