30.10 Rejecting Anonymous Calls
You can configure the device to reject anonymous calls received from the IP and destined
for an FXS port. This can be configured using the ini file parameter,
RejectAnonymousCallPerPort. If configured, when an FXS interface receives an
anonymous call, the device rejects the call and responds with a SIP 433 (Anonymity
Disallowed) response. For a description of the parameter see ''Caller ID Parameters'' on
page 905.
30.11 Configuring FXS Distinctive Ringing and Call
Waiting Tones per Source/Destination Number
You can configure a distinctive ringing tone and call waiting tone per calling (source) and/or
called (destination) number (or prefix) for IP-to-Tel calls. This feature can be configured per
FXS endpoint or for a range of FXS endpoints. Therefore, different tones can be played per
FXS endpoint depending on the source and/or destination number of the received call. You
can also configure multiple entries with different source and/or destination prefixes and
tones for the same FXS port.
Typically, the played ring and/or call waiting tone is indicated in the SIP Alert-info header
field of the received INVITE message. If this header is not present in the received INVITE,
then this feature is used and the tone played is according to the settings in this table.
Notes:
• This page is applicable only to FXS interfaces.
• The Tone Index table can also be configured using the table ini file parameter,
ToneIndex or CLI command, configure voip > gw analoggw tone-index.
To configure distinctive ringing and call waiting per FXS port:
1. Open the Tone Index Table page (Configuration tab > VoIP menu > GW and IP to IP
> Analog Gateway > Tone Index).
2. Click Add; the following dialog box appears:
Figure 30-8: Tone Index Table Page

waiting tones of Index #9 ('Priority Index' 1) in the CPT file for FXS endpoints 1 to 4
when a call is received from a source number with prefix 2.
