Hi,

I just installed issabel and want to configure fax. I have two analog pstn channel. I created two virtual fax and IAX2 devices for virtual faxes. Its connected to the IAX2 devices and says that Running and idle.

When i try to send fax from fax2 to fax1, fax2 says that no local dial tone.

When i investigate logs i found this error:
[2019-11-04 13:36:10] ERROR[7612]: chan_iax2.c:5018 handle_call_token: Call rejected, CallToken Support required. If unexpected, resolve by placing address 127.0.0.1:40000 in the calltokenoptional list or setting user 600 requirecalltoken=no

I checked secrets and its absolutely correct.
I changed two IAX2 device's requirecalltoken setting to no and it works now.

Is this configuration required? I think now secrets are useless and its connects without password.

Also i found this logs repeatedly when i change IAX2 settings:
chan_iax2.c:9048 update_registry: Restricting registration for peer '600' to 60 seconds (requested 300)

Thanks,
