I unchecked all codecs and called the mobile number with only one codec activated at a time.
Here's the result:
G722 - 16 kHz (dialled, but broke connection with "not acceptable here" when I answered)
GSM - did not dial ("not acceptable here")
speex - did not dial ("not acceptable here")
iLBC - 8 kHz (worked, but poor quality)
PCMU - 8 kHz (worked, but poor quality)
PCMA - 8 kHz (worked, but poor quality)
Not an encouraging result, I'm afraid.
