<!-- Kamailio Project uses GitHub Issues only for bugs in the code or feature requests. Please use this template only for bug reports.

If you have questions about using Kamailio or related to its configuration file, ask on sr-users mailing list:

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.

If there is no content to be filled in a section, the entire section can be removed.

You can delete the comments from the template sections when filling.

### Description While doing a call, new dialogue is not created in PCSCF. RX feature is on. As per my understanding, ims_dialog has one call back function and it invokes dlg_onreq() function and a new dialgue can be created (function is dlg_new_dialog). And in the traces, that is not happening.

<!-- Explain what you did, what you expected to happen, and what actually happened. -->

### Troubleshooting I have added additional traces for troubleshooting, and I can see that in case of PCSCF, new dialog is not created. And later on Rx feature is not working as expected. #### Reproduction Everytime <!-- If the issue can be reproduced, describe how it can be done. --> Need to do Two UEs VoLTE registration and then a call from UE1 to UE2

#### 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 bt full info locals list

If you are familiar with gdb, feel free to attach more of what you consider to be relevant. -->

<!-- Check the syslog file and if there are relevant log messages printed by Kamailio, add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site). -->

``` (paste your log messages here) ```

#### SIP Traffic

<!-- If the issue is exposed by processing specific SIP messages, grab them with ngrep or save in a pcap file, then add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site). -->
