[Asterisk-Users] Polycom NTP issue

[Rich Adamson]

I don't have a polycomm manual handy, but I think I'd change the
overrideDHCP parameter to "1" and test. You are apparently in the PST 
timezone?

If that doesn't do it, my next step would be to use ethereal to capture 
one of the ntp request/response pkts and analyze the content. If that 
looks okay, then something in the phone isn't right.
