If you have difficulty with the telephones, please try the suggestions below. For customer service, visit our website at

The telephone does not work at all.
Make sure the Cat-5 network cable is plugged firmly into the network wall jack.
Check that your network is providing Power over Ethernet (PoE).
Disconnect the telephone base from the network wall jack and connect a different SIP telephone that has been verified to function
properly. If the other SIP telephone does not work, the problem is probably in the wiring or network server. Check your SIP server
settings. Refer to the SIP Phone Configuration Guide for details.
There is no dial tone.
Try all the above suggestions.
The Cat-5 network cable may be defective. Install a new Cat-5 network cable.
Check that your network is providing Power over Ethernet (PoE).
Disconnect the telephone base from the network wall jack and connect a different SIP telephone that has been verified to function
properly. If there is no dial tone on this telephone either, the problem is in your wiring or network server. Check your SIP server
settings. Refer to the SIP Phone Configuration Guide for details.
Ensure that the phone has finished the initialization and system registration process by monitoring any LED activity for a 2-minute
period. The speakerphone key blinks twice every second if there are errors with the initialization and system registration process.
Check your SIP server settings. Refer to the SIP Phone Configuration Guide for details.
I cannot dial out.
Try all the above suggestions.
Make sure there is a dial tone before
dialing.
Your hotel’s dialing plan may require a prefix, such as dialing 9, for some internal or external calls. Check that the number dialed
contains any necessary prefixes. Refer to the SIP Phone Configuration Guide for details.
Check your SIP server settings. If other SIP telephones in your hotel are having the same problem, the problem is in the wiring or
network server. Contact your telephone service provider (charges may apply).
A Speed Dial key does not work at all.
The Speed Dial key may not be properly programmed. Check your telephone’s administrative settings. Refer to the SIP Phone
Configuration Guide for details.
The telephone does not store the last number dialed.
For security purposes, the last number dialed in the REDIAL memory will be automatically cleared after 15 minutes.
The telephone does not ring when there is an incoming call.
Make sure the Cat-5 network cable is plugged in properly (pages 10, 12 and 14).
Check that your network is providing Power over Ethernet (PoE).
Check your SIP server or telephone administrative settings. Refer to the
SIP Phone Configuration Guide for details.
The Cat-5 network cable may be defective. Install a new Cat-5 network cable.
There is interference during a telephone conversation.
Disconnect the telephone base from the network wall jack and connect a different SIP telephone that has been verified to function
properly. Check your SIP server settings. If calls are still not clear, the problem is probably in the wiring or network server. Contact
your telephone service provider (charges may apply).
If other SIP telephones in your hotel are having the same problem after checking your SIP server settings, the problem is in the
wiring or local telephone service. Contact your telephone service provider (charges may apply).
The telephone cannot register to the SIP network server.
Check that your network is providing Power over Ethernet (PoE).
Once installed, the telephone begins a four-step initialization and system registration process (pages 10, 12 and 14). All lights go
off when the initialization and system registration process completes.
If there is an error during the initialization and system registration process, the
/SPEAKER key of S1110/S1210/S1220/S2100/
S2210/S2220 blinks twice every second; the IN USE light of S2211 blinks twice every second; the LINE 1 key of S2221 blinks
twice every second. Disconnect the Cat-5 network cable from the network wall jack and connect it back into the network wall jack
with Power over Ethernet (PoE) to start the initialization and system registration process again.
