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.
NOTE:
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.

RTP Parameters section
The RTP parameters define the specification of the RTP audio packets. The most important
parameter is the RTP Packet size (time) which defines the interval of transmission of the RTP
packets. It is extremely important that time interval matches the ITSP settings. Its default value
is 0.030 (30 milliseconds).
NOTE:
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.
Reg Retry Long Random
Delay
Random delay range (in seconds) to add to <Register Retry Long Intvl>
when retrying REGSITER after a failure.
Default:
0
(disabled)
Reg Retry Intvl Cap
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)
SIT1 RSC
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.
SIT2 RSC
SIP response status code to INVITE on which to play the SIT2 Tone.
SIT3 RSC
SIP response status code to INVITE on which to play the SIT3 Tone.
SIT4 RSC
SIP response status code to INVITE on which to play the SIT4 Tone.
Try Backup RSC
SIP response code that retries a backup server for the current request.
Retry Reg RSC
Interval to wait before the SPA9000 retries registration after failing
during the last registration.
