Parameter
Description
Use Display Name as
Source Number
[UseDisplayNameAsS
ourceNumber]
Determines the use of Source Number and Display Name for IP-to-Tel
calls.
[0]
No = If IP Display Name is received, the IP Source Number is used
as the Tel Source Number and the IP Display Name is used as the Tel
Display Name. If no Display Name is received from IP, the Tel Display
Name remains empty (default).
[1]
Yes = If an IP Display Name is received, it is used as the Tel Source
Number and also as the Tel Display Name, and Presentation is set to
Allowed (0). If no Display Name is received from IP, the IP Source
Number is used as the Tel Source Number and Presentation is set to
Restricted (1).
For example: When 'from: 100 <sip:200@201.202.203.204>' is received,
the outgoing Source Number and Display Name are set to '100' and the
Presentation is set to Allowed (0).
When 'from: <sip:100@101.102.103.104>' is received, the outgoing Source
Number is set to '100' and the Presentation is set to Restricted (1).
Enable Contact
Restriction
[EnableContactRestri
ction]
Determines whether the device sets the Contact header of outgoing
INVITE requests to ‘anonymous’ for restricted calls.
[0]
= Disabled (default)
[1]
= Enabled
Play Ringback Tone to
IP
[PlayRBTone2IP]
Determines whether or not the device plays a ringback tone (RBT) to the IP
side of the call (IP-to-Tel calls).
[0]
Don't Play = Ringback tone isn't played (default).
[1]
Play = Ringback tone is played after SIP 183 session progress
response is sent.
If configured to 1 ('Play') and EnableEarlyMedia = 1, the device plays a
ringback tone according to the following:
For CAS interfaces: the device opens a voice channel, sends a
183+SDP response, and then plays a ringback tone to IP.
For ISDN interfaces: if a Progress or an Alert message with PI (1 or 8) is
received from the ISDN, the device opens a voice channel, sends a
183+SDP or 180+SDP response, but doesn't play a ringback tone to IP.
If PI (1 or 8) is received from the ISDN, the device assumes that
ringback tone is played by the ISDN switch. Otherwise, the device plays
a ringback tone to IP after receiving an Alert message from the ISDN. It
sends a 180+SDP response, signaling to the calling party to open a
voice channel to hear the played ringback tone.
Notes:
To enable the device to send a 183/180+SDP responses, set
EnableEarlyMedia to 1.
If EnableDigitDelivery = 1, the device doesn't play a ringback tone to IP
and doesn't send 183 or 180+SDP responses.
Play Ringback Tone to
Tel
[PlayRBTone2Tel]
Determines the method used to play a ringback tone to the Tel side. It
applies to all trunks that are not configured by the parameter
PlayRBTone2Trunk. Similar description as the parameter
PlayRBTone2Trunk.
[0]
Don't Play = Ringback tone isn't played.
[1]
Play Local = Ringback tone is played to the Tel side of the call when
180/183 response is received.
