Calling in Local Mode
In this scenario, the IP Phones at the SRG are in Local Mode because the
WAN is down. The SRG IP telephones are reregistered to the SRG and call
forward BUID is inactive on these telephones. These IP Phones are registered
at the SRG, and call forward BUID is inactive on these telephones.
The inset shows a main office call to SRG telephones. The user must dial the
SRG DN for the IP telephone (6002 instead of 3002). In this case, the user
dialing is different in the following ways:
• DN 3001 can call DN 3002 by dialing 65043002, instead of 3002.
• DN 3101 can call DN 3002 by dialing 3002, instead of 65013002 dialed
in Normal Mode.
• DN 3002 can call DN 3001 by dialing 65013001, instead of 3001 dialed
in Normal Mode.
• DN 3002 can call DN 3101 by dialing 3101 instead of 65043101 dialed
in Normal Mode.
