Re: [Linphone-users] std::bad_cast exceptions in liblinphone/src/db/main-db.cpp (4.4.21)

[Peio Rigaux]

Hello Denis.

Sorry for the late reply...

I'm forwarding you message to my colleague responsible of the desktop version.

We have locked accounts creations in our Gitlab for multiple reasons, one of which is we do only want to manage customers on our Gitlab instance.

For urgent matter, please contact me directly, as I only check mailing lists every once in a while...

Regards,

Peio Rigaux
