Hi all, I've got a .wav file on my asterisk server and I've got an extension that plays it back. When I dial the extension on the local server, it plays back just fine. When I create a call file that calls a (remote) pstn phone number and plays that file, it works just fine, also. But, when I change that call file to use a different voip provider, it tries to play the file, but the person only hears silence. I'm assuming that the second provider is wanting a different codec from the local asterisk server and the first provider. However, I was also expecting asterisk to transcode and "do the right thing." What am I missing? TIA, -- Mike Diehl
