Hello All, I am running Asterisk version 0.9.0 on Linux Redhat 9.0. To make Meetme work, I load ztdummy module before running asterisk. Then I can make a meetme conference call, but the voice prompt quality is very poor. It seems asterisk PBX sends voice data to the phone in a very low rate. When I call MusicOnHold and VoiceMail, the symptom is the same. When I remove ztdummy module, MusicOnhold and VoiceMail and other voice prompts are OK, but MeetMe does not work of course. Should I set ztdummy or something else? Please help. Thank you very much. Regards, Oliver Ren
