Mailing list is not a premium/paid support channel, people respond there in a best effort manner. Not getting a response there does not mean that there are people answering on the bug tracker, because this one is for reporting issues in the c code. See the next comment, likely it is the same case:
- https://github.com/kamailio/kamailio/issues/3555#issuecomment-1708653171
Discussing further has to be done on the mailing list.
