Hopefully people wouldn't mail you offlist! If they trust what they are saying, why don't they share it with ALL of us? :-) That's what the list is all about. Are you saying that instead of hearing the voice conversation, you hear silence for the first 10-15 seconds? That almost sounds like a software bug or even a hardware problem. I can't see anything in your config that would cause this, though maybe somebody else will. Even if you have busied out the WAN as you say, it's supposed to handle this correctly. If it was just a second or two of silence, I would say tune your Voice Activity Detection (VAD), but 10-15 seconds, that's really bizarre. Anyone else have some ideas? _______________________________ Priscilla Oppenheimer www.troubleshootingnetworks.com www.priscilla.com > Sorry about the duplicate. > > ******************* > Well, this should give you enough to chew on since voice is > becoming a hot topic.
