Paul,

In general your patch works - now log says

    [format] => mulaw

and

 ToneSource::ToneSource(0xc4f074) 'milliwatt' [0x91280f8]
 Created DataTranslator 0x9155ac0 for 'slin' -> 'mulaw' by factory
0xf91468 (len=1)
 DataTranslator::attachChain [0x91280f8] 'slin' -> [0x9146588] 'mulaw'
succeeded

But the sound is still distorted. I have played with bitswap at wpcard.conf
- the sound was different and still highly distorted.

Any ideas on the problem? We have Sangoma A104u on yate side which works
perfect with another telco.

Regards,
Andrew
