Termination cause codes
General configuration=
When configuring termination cause codes, use the following table as a guide. The Drop column represents codes to use when redirection contents should be dropped and the call should be terminated with the specified code. The Forward column represents codes to use when redirection contents should be forwarded to the incoming leg with the specified code. If the redirection requests must be processed, the codes are not used.
| Code | Drop | Forward | ||
|---|---|---|---|---|
| SS7 | SIP | SS7 | SIP | |
| 14 | 21 | 603 | 14 | 300 |
| 22 | 21 | 410 | 22 | 301 |
| 23 | 21 | 410 | 23 | 302 |
| 300 | 21 | 603 | 23 | 300 |
| 301 | 21 | 410 | 22 | 301 |
| 302 | 21 | 410 | 23 | 302 |
| 305 | 21 | 603 | 23 | 305 |
| 380 | 21 | 603 | 23 | 380 |
For each redirection cause code, choose Process to let the routing scripts process the redirection. Choose Stop to drop calls when receiving a redirection and use the above table to specify if the redirection contents should be dropped.
Starting from release 2.5.55 these cause codes can be modified with the Web portal in

Case for the 603 DECLINE and 200 TOOLPACK NORMAL
The TOOLPACK_NORMAL reason code is mapped to the 603_DECLINE reason code. The reason for this is the following:
A SIP BYE does not include a cause code, so on a normal call terminations, TMedia will send a BYE on SIP, and internally, a 200 TOOLPACK_NORMAL (in the logs and the CDRs). When the call terminates unexpectedly, for example after a ACM, but before a ANM, Tmedia will still send a BYE on SIP, but internally, it will log a 603 Decline (REASON_CODE_603_DECLINE).
