Linphone on Blackberry Q10 most of the time produces no in-call audio, only 
cracklings. Sometimes you can hear sound if you switch from speaker to earphone 
vice versa but also with cracklings. It works correctly only about 1 time in 
10. You can see lots of warnings in logs:

WARNING ms_qsa_write_process: Removing extra data for sound card (960 bytes)

Debug logs were uploaded and sent to the developers. Taki (another softphone 
for Blackberry) works fine. The problem could be in too small audio buffer, as I
face the same issue with Linux version of Linphone with Pulseaudio and forced 
to use Alsa Linphone backend.

Also the dialpad is squeezed on Q10, the program was probably tested on Z10 or 
other devices with wide screens:
