Please try to fill this template as much as possible for any issue. It helps the
developers to troubleshoot the issue.
Note that an issue report may be closed automatically after about 2 months
if there is no interest from developers or community users on pursuing it, being
considered expired. In such case, it can be reopened by writing a comment that includes
the token `/notexpired`. About two weeks before considered expired, the issue is
marked with the label `stale`, trying to notify the submitter and everyone else
that might be interested in it. To remove the label `stale`, write a comment that
includes the token `/notstale`. Also, any comment postpone the `expire` timeline,
being considered that there is interest in pursuing the issue.

### Description
During de-registration, Kamailio receives REGISTER (with expire 0), and then send Session
Termination request, and only after getting Session Termination Answer, Kamailo sends
200OK. This is not sent till UE. The reason is after receiving Session Termination
Request, the PCRF sends ReAuthRequest towards PCEF and it followed delete bearer procedure
in IMS-PGW and bearer is getting deleted :(.
<!--
Explain what you did, what you expected to happen, and what actually happened.
-->
In the kamailio script, pcscf_save() is used after receiving 200OK from SCSCF. And within
this function, STR is sent and STA received.
### Troubleshooting
#### Reproduction

-->
RX_SUPPORT flag shall be defined and it can be observed in De-registration procedure.
#### Debugging Data
<!--
If you got a core dump, use gdb to extract troubleshooting data - full backtrace,
local variables and the list of the code at the issue location.
gdb /path/to/kamailio /path/to/corefile
