The person that called me yesterday (PSTN via asterisk [sipgate])
mentioned a robotic voice. Echo cancellation was activated but I
didn't switched it off and tested again.
A direct call to a local Cisco IP Phone 7960 resulted in the
same audio effect. The phone plays the audio data slower,
e.g. saying "one..two..three.." within 3 seconds results in
"oooonnnneee... twwwooooo... ttthhhrrreeeee" on the Cisco IP Phone
which lasts about 5 to 6 seconds. Switching echo cancellation off
makes no difference. Sounds awful. Since the phone wasn't able to
speak GSM, I couldn't check if other codecs are ok.
