I have successfully installed jigasi, I know it because one of the tests
worked - clicking SIP, input number, call, pick up the phone, and I
could hear the sound on both sides.
However this has happened only once, and now everytime I try the call is
received by the phone, when picked up I hear sound for less than a
second, then the jitsi-meet icon of the phone becomes greyed out and
signifies a connectivity problem. When I hang up from the phone, the
call is canceled so the connection seems alright.
How can I debug this ?
