Response Status Code Handling section

The RSC handling defines the behavior of the user audio tones played under
specific conditions signaled by the network, such as congestion, queuing, etc. The
default settings (blank) are adequate is most circumstances.
These settings need to be compatible with the ITSP network settings. The ITSP
you use will inform you about any specific setting you need to modify on these
areas. These parameters have impact on the signaling and audio reliability.

Retry Reg RSC
Random delay range (in seconds) to add to <Register Retry
Long Intvl> when retrying REGSITER after a failure.
Default: 0 (disabled)
The maximum value to cap the exponential back-off retry
delay (which starts at <Register Retry Intvl> and doubles on
every REGISTER retry after a failure). In other words, the retry
interval is always at <Register Retry Intvl> seconds after a
failure. If this feature is enabled, <Reg Retry Random Delay>
is added on top of the exponential back-off adjusted delay
value.
Default: 0 (disables the exponential back-off feature)
SIP response status code for the appropriate Special
Information Tone (SIT). For example, if you set the SIT1 RSC
to 404, when the user makes a call and a failure code of 404
is returned, the SIT1 tone is played. Reorder or Busy Tone is
played by default for all unsuccessful response status code
for SIT 1 RSC through SIT 4 RSC.
SIP response status code to INVITE on which to play the SIT2
Tone.
SIP response status code to INVITE on which to play the SIT3
Tone.
SIP response status code to INVITE on which to play the SIT4
Tone.
SIP response code that retries a backup server for the
current request.
