Okay, I have a customer out there with a 540 (the only 540 I sold) where they will call me, from one of their VOIP phones, via their SIP trunk, to tell me they can't get on the Internet.
Obviously if their Internet connection had completely stopped we wouldn't be talking.
So I am able to RDesktop in through the 540 and access a PC in their office, and cannot use that PC to get to any web pages. The carp you say!
So the UC540 is basically still handing phone calls, it can still handle RDP, but it won't serve-up web pages.
This 540 has been in place for maybe nine months now, working pretty well. The call I got today was the 2nd time this happened. The first time it was maybe 3-4 weeks ago.
Any ideas on what I can check? The fix, BTW, seems to be power cycling the UC540. Next time I'm going to have them leave the UC540 and power cycle the cable modem (Time Warner). But any tips on diagnosing this would be appreciated.
Thanks!
