Need help with VoLTE Cal

[DipinJangid]

Hello,
First of all thank you very much for this amazing project and documentation. I'm following the tutorial from read.me file. I'm seeing below error in the logs after I ran "docker compose -f 4g-volte-deploy.yaml up" command.
log.txt
My first question is, is it normal, I did not make any additional changes, just changed DOCKER_HOST_IP. Also, it keeps going on like this and if I hit ctrl+c, all the containers are stopped. Is this also normal? At the moment I can see all containers in UP state.

I have one more query, I want to test VoLTE call, so I'm only really interested in IMS part of this deployment. I already have simulator eNB and EPC core + PCRF setup externally and I'll use that. Do I have to make any changes in .env file so that the PCSCF IP is reachable from the outside? I'm guessing I will have to give the IP that will be reachable, but any other change I have to make elsewhere?
Any sort of help would be much appreciated as I'm very much stuck here.

I dont see any errors in the log file, can you please point out specifically which error you are referring to?

Then, all are normal

Here are thing you needs to change:

1. Set correct SMF_IP, UPF_IP, HSS_IP
2. Also, ensure that traffic exiting the EPC machine does not NAT the IMS traffic. IMS does not work with NAT

I am not sure how you plan to test VoLTE since using a simulated eNB + UE would probably be able to achieve a VoIP call but wont be VoLTE call since it would involve tight integration between IMS client to the radio stack on the UE side.
