I have about 9 SPA504g phones with an SPA9000 and SPA400. I can't seem to get the date/times on these phones to stay in sync. I set the DNS and ntp fields, and I manually set the date/time. But the times wander either fast/slow, and they don't seem to ever get the ntp time. I have an open ticket at Cisco support, but they have no info on this. Are there any suggestions? Thanks.
