General Troubleshooting Tips

The suggestions in this section are general troubleshooting tips.

• If using a Æ DHCP server, make sure that it is operating correctly. The

DHCP server should show an incoming request from the Æ MAC ad-

dress listed on the product label.

• If you do not see the idle menu after you connect the Ethernet cable,

make sure the power cord and the Ethernet connection are secure.

• If you do not hear a dial tone, make sure that the telephone-handset

line cord is plugged into the IP Phone port. Also make sure that the ap-

propriate Ethernet cable (crossover or straight-through) is used, and

that all cable connections are secure.

• A fast-busy tone indicates that the number you called is not valid or that

external circuits are busy. Verify the number or try your call again later.

• If you place a call to another IP telephone, hear ringback, and the called

party answers but you cannot hear the speaker’s voice ("Incompatible

terminal"), verify that the optiPoint 410/420 family S V7.0 and the other

IP telephone support at least one common audio codec Æ page 165.

• In some cases it can be useful if you perform a update of the phone’s

software Æ page 74.
