Though I've used my SPA3102 for a couple of years, it has recently become problematic. I can hear occasional audible clicking from the device which is associated with a red light flashing briefly on the power LED. If I'm on the phone at the time, the call is terminated.
I'm hoping that a firmware upgrade will address the issue, but I've been unable to upgrade from 3.3.6 (GW). Though I'm on a Mac, I don't understand the firmware upgrade method using http or tftp. Fortunately, I run Windows XP on Parallels Desktop for Mac and have been able to run the upg-spa3102-5-1-10-GW.exe program. However, a message appears: SPA firmware upgrade error > Upgrade failed: No response from SPA.
Reading various forum posts on similar such problems I'm yet to find the solution.
I've turned off the firewall on my Mac, the ADSL router (D-Link DSL 504T) and Windows XP.
I've confirmed the SPA IP address is 10.1.1.3
I've ensured that firmware upgrade is enabled in Provisioning of the SPA's configuration.
I'd greatly appreciate some assistance please.
