Hello marian,
For the sms problem, I just found that the sms doesn't work only with my own written sim card. The sms worked fine with other sim card. I guess the problem is I didn't write that sim card correctly.
For the call record, after reading the yate documents and old topics, I did some configuration in regexroute.conf. I did record the wave file in .au file. But it seem like the quality was very bad, I could barely hear the voice. Any idea on how to fix this issue?
Regards,
Khem
