Parameter Description
Play Ringback Tone to
Tel
[PlayRBTone2Tel]
ƒ
Determines the method used to play Ringback tone to the Tel side. [0]
Don't Play = Ringback Tone isn't played.
ƒ
[1] Play Local = Ringback Tone is played to the Tel side of the call
when 180/183 response is received.
ƒ
[2] Play According to Early Media = Ringback Tone is played to the Tel
side of the call if no SDP is received in 180/183 responses. If 180/183
with SDP message is received, the gateway cuts through the voice
channel and doesn't play Ringback tone (default).
Use Tgrp Information
[UseSIPTgrp]
ƒ
[0]
Disable = Tgrp parameter isn't used (default).
ƒ
[1]
Send Only = The trunk group number is added as the 'tgrp'
parameter to the Contact header of outgoing SIP messages. If a trunk
group number is not associated with the call, the 'tgrp' parameter isn't
included. If a 'tgrp' value is specified in incoming messages, it is
ignored.
ƒ
[2]
Send and Receive = The functionality of outgoing SIP messages is
identical to the functionality described in option (1). In addition, for
incoming SIP messages, if the Request-URI includes a 'tgrp'
parameter, the gateway routes the call according to that value (if
possible). If the Contact header includes a 'tgrp' parameter, it is copied
to the corresponding outgoing messages in that dialog.
