Testing Audio Quality

I would like to make a test about the Audio quality in the Voip Internet Environment. I set up an Asterisk system connected to FWD dialup.
It will be glad if someone can leave a greeting test message in my mailbox calling the FWD number 858210. If required i will reply or call you back for testing purpose, so if you want be replied leave country, FWD number and GMT time of your availability.
When i’m in office (8:00 - 12:00 GMT) i will be glad to answer your calls for test.
Tnx, Fabio.
