[3] Play Local Until Remote Media Arrive = Plays the RBT
according to received media. The behaviour is similar to [2]. If a
SIP 180 response is received and the voice channel is already
open (due to a previous 183 early media response or due to an
SDP in the current 180 response), the device plays a local RBT
if there are no prior received RTP packets. The device stops
playing the local RBT as soon as it starts receiving RTP
packets. At this stage, if the device receives additional 18x
responses, it does not resume playing the local RBT.
Determines whether or not the device plays a ringback tone (RBT)
to the IP side for 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
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.
