6 months ago I had a look into pcap, it looks like an issue in open5gs. Can you try using the latest open5gs commits by modifying the commits hash here https://github.com/herlesupreeth/docker_open5gs/blob/f338aa9efdbf0ce017264e6340cbe5c78125728e/base/Dockerfile#L71 and recompile the base image?
btw, awesome work making use of FS as TAS :)

5 months ago Hi herlesupreeth,
still crashing, here is the logs again.
mme.log pcrf.log sgwc.log sgwu.log smf.log upf.log TRACE.zip
I use now FS as TAS and Asterisk as Voicemail and IBCF utilizing ENUM to route the calls to IBCF, it was quit a journey, still have issues with RTPs, RTPs flowing from UE directly from IP Addrese of the UE to FS was expecting from UE to RTPEngine then to FS

5 months ago I think its an issue in open5gs and would suggest to raise an issue in open5gs repo. Below is my breakdown of the scenario based on the pcap:
I think not having received Create Bearer Response before receiving Delete Bearer Request is causing SGW-C to crash.
Regarding the RTP issue you can take a look at this comment - https://github.com/herlesupreeth/docker_open5gs/issues/142#issuecomment-1420801379

5 months ago I will open an issue in Open5GS.
I dont know why the Iphone is rejecting the SDP with BYE, is it because there is not Bearer Response?
In the meantime the change in that comment solve the issue to all calls towards AS and term_unreg to Voicemail !! many thanks, the change could be more improved to be not only based on the User-Agent but for the time being it solve a big issue.
I see there is almost not guide on how to integrate FS and Asterisk as MTAS, I may write one when every things is stable is not so hard actually.

It could be that it not receiving sendrecv as part of SDP for INVITE
you could use this commits changes - https://github.com/herlesupreeth/docker_open5gs/commit/b14eecb9912615de6d5ba2cd2e2b6f06289ee10c as reference to alter the SDP parameters

Thanks for confirming it :). I have very less knowledge of working with AS so havent managed to come up with a generic solution
I see there is almost not guide on how to integrate FS and Asterisk as MTAS, I may write one when every things is stable is not so hard actually.
Looking forward to it

5 months ago I opened Issue#3109 regarding the SWGC, Hope get a solution for it.
I looked at the commit above its looks like its already there and doing his job maybe the IPhone is just dropping the call because there is no Bearer Response, Apple devices are know to be weird with there errors ;( I will try to connect it to a console I tried the case with OnePlus 9 Pro there is no BYE but the SGWC is still crashing

Notice that the changes in that commit is checking whether a line in SDP with a=inactive exists and only if it exists then modifies it. I would suggest you do the modification in FS to send 200 OK for INVITE with SDP containing a=sendrecv
IPhone is just dropping the call because there is no Bearer Response
I dont think so since all iPhone cares is whether it received Activate dedicated EPS bearer context request or not
I tried the case with OnePlus 9 Pro there is no BYE but the SGWC is still crashing
Can you post the pcap for this?

5 months ago @herlesupreeth I noticed that with OnePlus the SGWC is not crashing here the Request is sent to MME, and the MME is not responding to this request, there is also working cases in the trace also. mme.log pcrf.log sgwc.log sgwu.log smf.log upf.log good_and_bad_cases_f.zip
Regarding IPhone, those devices are really strange they have a SIP Stack called "Bambi" act really sometimes weird and its very sensitive and always has issues with payload types we had to implements workarounds sometimes on our P-CSCFs to cover there issues ;(. I recorded the logs from the console and the IPhone is complaining about missing Audio Settings:
Apr 5 12:00:33 iPhone CommCenter(libIPTelephony.dylib)[90]
not sure if he is expecting the RS/RR/AS, here is a working case between two devices over FS : VoLTE Call RTPs filteredOut.zip

5 months ago also related to a=sendrecv, the attribute is there looks like the P-CSCF is adding it on the Way to the UE

5 months ago Hi @herlesupreeth
with the new Fix from Sukchan, the flood of Error Indication, also almost stopped, the rest I think is on SRS eNB, it should react on this Error Indicator, after the session closed the Device still sends Traffic over the Tunnel after tear down, to my knowledge eNB should release the E-RAB, instead it throw an error in Log about Unhandled GTP-U Extension Header.
I still have an issue when the device wake up and try to make a call, the MME is not responding to "Create Bearer Request", I will open an new issue for it, you can close this issue. The Problem with IPhone is that it does not like the Mode-set and prefer to have one, I need to find a way to solve it, or to leave all MRF Tasks to Asterisk.

Hi,
I've setup VoLTE with FS as an MTAS, the call between the UEs ( two IPhones) works fine, but if I tried to call FS teh SGWC crashes :

I attached the PCAP and the logs i can reproduce the issue always.
