SIP User's Manual 108 Document #: LTRT-65411
MediaPack Series
Parameter Description
Use Display Name as
Source Number
[UseDisplayNameAsSou
rceNumber]
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).

INVITE requests to ‘anonymous’ for restricted calls.
[0] = Disabled (default)

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.
Notes:
This parameter is applicable only to FXS interfaces.
To enable the device to send a 183/180+SDP responses, set

Tel side of the call if no SDP is received in 180/183 responses. If
180/183 with SDP message is received, the device cuts through the
voice channel and doesn't play ringback tone (default).
