SIP on Fritz!Box: outgoing call rings (on the other side), but connection is immediately cut off on answering the call
I'm using Jami Desktop (on Fedora 31). I have set up a SIP account (connected to my Fritz!Box DSL router). Outgoing calls successfully ring (on the other side), but connection is immediately cut off on answering the call. SIP is know to work (with a DECT telefon connected to the very same Fritz!Box).
Any suggestion how I could debug the problem would be very welcome!
