Thanks for trying Alice but it doesn't sound as is CoolTalk will meet our needs.

The sound does break up on Hearme sometimes but overall, the sound quality is quite acceptable for our use and it does work with multiple locations and it even seems to work well for people with connections as slow as 28.8K.

Hopefully something will turn up one day but at the moment, it seems to be impossible to find anything that works as well as Hearme but provides Mac support.

I suspect that the most likely solution lies with the PC/ Windows emulation software for the Mac but I am not in a position to help in the testing of such software.
