I have built linphone 3.1.2 on my embedded linux system running on Cortex ARM A9. I didn't have access to the latest libraries to allow newer versions of linphone to be installed.
The system works well, and I can make and receive calls. I can register different users, etc.
However, one system we have which has had linphone installed in exactly the same way, can register users, but when you make a call, it crashes the whole of Linux such that I need to power cycle the unit before I can do anything else with it, or connect via SSH, etc. Is there anything within a call handling that could take out the whole of Linux?
