I have tried to configure a simple Access service as:
https://github.com/jj1682000/librec_sbc_config_public/blob/master/minimal_access

But the User, (SIP Client, Linphone) can not connect to sbc02.

Thank you for your help.

I created two test user with directory_testuser.json and directory_testuser01.json.
both users above can connect to sbc02.sample.com. but they can not call another one.

you can refer below suggestion, I suppose that call direction is from testuser --> testuser01: then
testuser dial testuser01, ----> LibreSBC (here you config routing route to PBX) ----> PBX (here you config PBX send call back to SBC) ----> LibreSBC (here you config routing route to access service of usertest01) ---> testuser01

Thanks for your answer!

Can you help me to check if "LibreSBC (here you config routing route to PBX)" and "LibreSBC (here you config routing route to access service of usertest01)" in my config is correct?
https://github.com/jj1682000/librec_sbc_config_public/blob/master/minimal_access/README.md#config

Can I contribute my configuration for different use cases to your wiki?

jj1682000 Apr 19, 2023

I resolved it! because the dialplan of default config in freeswitch only support digital extensions.

Test external call from ext 1007 to 1008.

Error: [USER_NOT_REGISTERED] in logs of freeswitch02
because 1007 and 1008 only register in sbc02, no register in freeswitch02.

so, any ideas?

config here

The LibreSBC is a register server by default, like below:
[UAC] ---REGISTER---> [LibreSBC (register server)]

Can I config the LibreSBC as a register proxy, like below:
[UAC] ---REGISTER---> [LibreSBC (register proxy)] ---REGISTER---> [FreeSwitch (main register)]
