CHAPTER 69 Testing SIP Signaling Calls
'Play'
play
[Test_Call_Play]
Parameter
Mediant 800 Gateway & E-SBC | User's Manual
Description
Note: The parameter is applicable only if you configure
'Call Party' to Caller.
Enables the playing of a tone to the answered side of the
call.
■ [0] Disable = No tone is played.
■ [1] DTMF = (Default) Plays (loop) a user-defined
DTMF string, which is configured in
DTMF Tones for Test
■ [2] PRT = Plays (loop) a pre-recorded tone (audio file)
from the PRT file that is installed on the device. You
can either specify the tone (by index) to play from the
PRT file in the 'Play Tone Index' parameter (below), or
implement a basic NetAnn feature whereby the tone
from the PRT file (and other characteristics) are
specified by NetAnn parameters in the Request-URI
of the incoming SIP INVITE message. When using
NetAnn, instead of connecting the call (i.e., 200 OK),
the devicereplies with a SIP 183 containing SDP.
The NetAnn parameters include the following:
● early=yes: Indicates that NetAnn is used for
playing the tone.
● play=<Prompt/Tone Index in PRT file>:
Defines the tone to play from the PRT file.
● repeat=<Times>: Defines how many times the
tone is played (loops) before the device
disconnects the call.
● delay=<Delay Time>: Defines the delay time (in
msec) between each played (loop) tone. If the
parameter is not present, the default is 2,000 ms
(2 seconds).
The following shows an example of a Request-URI
with NetAnn parameters that instruct the device to
play three times (loops) the tone that is defined at
Index 15 in the PRT file:
INVITE
sip:200@1.1.1.1;early=yes;play=15;repeat=3
Note:
■ You can configure the DTMF signaling type (RFC
2833 or in-band), using the 'Play DTMF Method'
parameter (above).
■ Playing a tone from the PRT file requires DSP
resources if the coder with which the tone was
created is different to the coder used for the Test Call.
■ You can also use NetAnn parameters to play a
specific recorded tone to the caller (source) when the
destination fails for a regular IP-to-IP SBC call. To
configure this:
