Hi, I tested the Pocket PJ app on two HTC devices with Windows Mobile 6. The clients are registered to my Asterisk server, running on PCMU codec Call is thru with voice output but both devices has a lot of noise and is not clear. Tried GSM codec and played around with the Echo suppressor settings but no difference in noise. How can I solve this problem? Thanks.
