Well, its been all of one day and already I’ve discovered a problem with my Sipura SPA-841. The phone apparently suffers from the same power-line-noise problem that the SPA-2100 terminal adapters do. Its an ever-present electrical noise on the phone – even when you’re dialing.
I would have hoped that Sipura had worked out this issue a long time ago, especially since so many customers have complained about it in their terminal adapters. It turns what was initially a fantastic choice for a low-end IP phone into a crapshoot at best. How long until the noise on the phone overpowers the speech? From my experience with the TAs, this problem is only going to get worse.
I’ll keep an eye out for future degredation, but I’m not hopeful. Sadly, purchasing Sipura products is still a gamble.
