QuickCam Audio using ISDN Connections?

Can we transmit/receive audio with Connectix QuickCam and CU-
SeeMe between 2 school sites? We both have a Macintosh on an
ISDN connection. We are receiving broken audio on my end and no
audio on the other. I tried using a Macintosh microphone, but
still was unable to transmit audio to the other school. Any tips
or should we give up on audio? (Video is working fine.)
