enabled, the Caller ID detected on the FXO port will be send to the SIP Proxy Server on dialing out
calls.
Detection Level: If FXO can’t detect Caller ID, try to adjust it until it can.
You have to enable

detected correctly
.
FSK Caller ID Type: Select FSK type. In most cases, Bellcore is preferred in North America and
ETSI in Europe.
Anonymous Caller ID (CLIR): When enabled, the caller’s phone set will not display your number.
If you register the VoIP gateway to a Proxy, you may be unable to make a call. This is
due to the fact that the VoIP gateway doesn’t send the number for authorization.
Anonymous Transit in W/O Caller ID: FXO won’t detect caller ID, and the gateway will dial out
with an anonymous caller identficiation. If the call needs caller ID to be identified for Proxy, Proxy
will reject this call without caller id.
