The call is not successful because there is no dedicated bearer created for VoLTE Audio for any of the UEs.
I would suggest to take a trace on 'any' interface to debug this issue
Thank you !! Attach zip file include pcap file with any interface. , kamailio log and FoHSS log. (sorry it just captured and just confirm wireshark can be opened. I still not check it.)
I did as follow. 1) run 'tcpdump -i any -w volte_any.cap' on ubuntu virtual machine 2) configure IPs 3) start FoHSS as 'sh /root/hss.sh' 4) start kamailio P-cscf as 'mkdir -p /var/run/kamailio_pcscf;kamailio -f /etc/kamailio_pcscf/kamailio_pcscf.cfg -P /kamailio_pcscf.pid -DD -E -e' 5) start kamailio S-cscf as 'mkdir -p /var/run/kamailio_scscf; kamailio -f /etc/kamailio_scscf/kamailio_scscf.cfg -P /kamailio_scscf.pid -DD -E -e' 6) start kamailio I-cscf as 'mkdir -p /var/run/kamailio_icscf; kamailio -f /etc/kamailio_icscf/kamailio_icscf.cfg -P /kamailio_icscf.pid -DD -E -e' 7) restart Open5GS as 'systemctl restart open5gs-*' 8) power on iPhone X/iOS 12 then connect 9) power on iPhone 12 Pro/iOS 14 then connect 10) make call from iPhone 12 Pro to iPhone X 11) cancel the call after I see SIP CALCEL transaction. 12) make call from iPhone X to iPhone 12 Pro 13) cancel the call after I see SIP CALCEL transaction.

Can you tell me why you are assigning 172.24.15.30 IP to ogstun2?
I still see the same issue, there is no dedicated bearer for VoLTE call. Check SMF and MME logs
172.24.15.30 is for P-cscf. in my understanding, apn name "ims" is used ogstun2. thus, I assign it. is it wrong ?
Attached are mme and smf log for these period. SMF was rebooted during this period. after UE B(IMSI : 001010000000024. this is iPhone 12 Pro) had been connected.

after rebooted, below below error was happen.

Also, UE A gets only IPv4 address. but UE B gets both IPv4 and IPv6. will check disable IPv6 for UE B smf20220308.log smf20220308_org.log .
Hi @yasuhirom
If you want to try VoLTE quickly, I recommend the following.
https://github.com/herlesupreeth/docker_open5gs
If you would like, please also refer to the following little note I wrote.
https://github.com/s5uishida/docker_open5gs_volte_sms_config
Hello @s5uishida
Thank you for your advice. because I uses non native ubuntu machine, I affraid performance issue when I use Docker environment on Virtual Machine. but, yes, if my debugging is not going well, I will try it.
Thank you!
Hi @yasuhirom
I built an Ubuntu 20.04 VM(6 CPUs, 8 GB Mem) on VirtualBox using SSD for storage. I have not confirmed the performance, but could make VoLTE calls.
For your reference.
hello @s5uishida
Thank you for your information! my laptop has Core i5 7 gen / 8GB memory. so, it is hard to apply same configuration. but it is good infomation.
Thank you !
try to disable IPv6 for UE B was not help. situation is unchanged.
I confirm SMF is rebooted when I make the call. and reboot is happen only 1st time. After rebooted, I reattached the UEs (toggle Airplane mode). then make call. but SMF still alive. not rebooted. (Still no RINGING).
will check the reason SMF rebootting.
found PCRF was crashed after error. then SMF going to reboot.
I'm asking Open5GS people regarding PCRF issue.
Hi @yasuhirom
It also worked with the following resources:
[Host PC]
[docker_open5gs VM]
FYI.
Hi @s5uishida
thank you fir your information. Today , I started to install it in parallel to debug this issue. Install was done. But external eNB can't attach MME. Ping to eNB is not reach from mme container . I have some questions. Will ask these on docker_open5gs project.
hi, I'm trying to make 2 UEs(iPhone X/iOS 12 and iPhone 12 Pro/iOS 14) with VoLTE call. Open5GS w/ Kamailio. I setted up followed https://open5gs.org/open5gs/docs/tutorial/02-VoLTE-setup/
now, The SIP REGISTER for both UEs are success. but when I make call, SIP INVITE and SIP PRACK is made. then nothing to next. (probably RING) After some time, SIP CANCEL is issued by time out. I read other thread and reduce MTU to 800. but not success.
Do you have any chance to check my configuraiton ?
attached are log, configfile for open5GS and p/s/i-cscf by kamailio and pcap between eNB and EPC. because I run kamailio_pcscf,scscf,icscf as command line (follow the above instruction), the log is saved from screen for terminal application (I use ssh to login my virtual machine. ssh is runnign comamd prompt) therfor, the log is only last part and limited.
hardware configuration is
