chan_capi and poor voice quality
Hi,
after getting the chan_capi error messages sorted out, I have another
question.
Calling * via SIP produces very good sound. Calling * via the chan_capi
produces horrible sound. However, if I dial 500 in the demo menu to
connect to the IAX at digium the sound is good again. ie:
ISDNCall->AVM-B1-Card->Asterisk = All prompts sound horrible
SIP->Asterisk = Prompts are good
ISDNCall->AVM-B1-Card->Asterisk->IAX->Digium-Asterisk => Prompts are good
Any ideas are greatly appreciated.
