Trying to move forward #444

Rashed97 and others added 5 commits April 9, 2026 10:36
Currently the P-CSCF can handle LTE-LTE and NR-NR communications.
Cross-technology communications are still a work in progress.
Using the PANI header, we can determine what interface this UE should
register via.

TODO:
- Implement detection for additional network types (ex. for IWLAN)
- Add some sort of database store for network access type, to be used
  in the mt config, as P-CSCF cannot query the network type from the
  device before starting a call
MT is currently broken due to the lack of a PANI header. This needs
to be reconfigured to read out of a database that has updated values
that are written during UE registeration.

This approach doesn't work for me.

@herlesupreeth I've tested your voip_and_inter_rat branch with LTE UEs without issues. I'm trying to get a 5G working scenario to test the mix yet.

Thanks for trying that branch.. sorry i couldn’t review your MR. For now Rx and N5 inter working works for registration. I am still working on calling part. My goal is to have the calling between voip client and VoLTE/VoNR client
