Problem with linphone-nogtk 5.1.65 on armbian bookworm

Hello everyone,

I recently installed the version "Armbian 23.11.1 bookworm" on an old Odroid C2, mainly to run Openhab there. Now I wanted to be informed about certain events on my Fritzbox (e.g. window open for too long) via linphone and I also found instructions for this:

https://community.openhab.org/t/make-dect-phones-e-g-fritzfons-connected-to-fritzbox-ring-as-alerting-mechanism-from-openhab-should-be-useful-also-to-have-openhab-make-arbitrary-phone-calls-with-alerts-announcements/132940

I installed the package “linphone-nogtk” with version 5.1.65-4.

If I type on the console the following commands:

linphonecsh init
linphonecsh register --host fritz.box --username <username> --password <password>
linphonecsh dial **610

I get the following error message:

Call 1 with sip:**610@fritz.box error.
Error from linphone_core_invite.

Unfortunately, after a lot of Googling, I couldn't find anything helpful about this error message.

However, a test under Ubuntu 20.04 with version 4.4.21 of the package and another test on a Raspi under "Raspbian GNU/Linux 10 (buster)" with version 3.12.0 of the package were successful. The internal telephone rings there and no error message is displayed.

Is anyone able to help me? Is this perhaps a bug in version 5.1.65 or does something still need to be configured/installed? I run the Odroid without a monitor, so everything should only run on the console. What does the error message “Error from linphone_core_invite.” mean?
