Segmentation Fault after dialing not more than 2 seconds from the Raspberry Pi 3 Model B+

Brandon Cheah

I can dial outgoing call using linphone console application (linphonec) in the RPi 3 Model B+ for the past few months until yesterday the problem arise.

The problem is that after typing “ call myusername “ in the linphonec console application, my phone rings but after 2 seconds of not picking up the phone call, the Raspberry Pi console application shows Segmentation Fault and then exits the console application.

If I pick up the phone call within 2seconds, I can establish a voice/video call without any problem.

Can somebody help me with this error, much appreciated!!

I’ve tried debug with gdb and this is what I get:

gdb ./linphonec

run --verbose

(gdb) run -C

Starting program: /home/pi/linphone-desktop/OUTPUT/no-ui/bin/linphonec -C
