Cisco Small Business SPA112 2-Port Phone Adapter

1 out of 5 eggs echo echo 03/27/2014

This review is from: Cisco Small Business SPA112 2-Port Phone Adapter

Pros: works, except for the echo problem...

Cons: echo. The calling party can hear everything they say echoed back to them very loudly, with about a 1/2 second delay or so, thereby making it impossible for them to concentrate on the conversation with you.
I called cisco's tech support but I called the wrong number on their web site - I called the number for their consumer products. So I had to hang up and call the number for their business products. I got connected with a tech in Bulgaria who was very nice, had very good English, but insisted that before he could help me, I would have to create an account on the cisco web site. So while he waited on the line I tried to create the account, but it wouldn't accept my registration because I couldn't seem to get a password that was acceptable, despite trying different combinations of letters, numbers, caps and non-caps, special characters, no special characters, etc. I just decided to give up and return the devices to newegg. Same problem on both the SPA122 and the SPA112, using the service provider named callcentric. Callcentric provided all the settings specific to this device, and I also flashed these devices to the latest firmware. I hunted around for echo settings, and the echo cancellation is turned on. I couldn't find any settings to adjust the input/output gain of the phone jack. googled around for solutions, found none. Made sure to put the calling and called phones in different rooms to eliminate all feedback, and echo was still there on every call.
I'm guessing that the echo has always been there on phone calls, but on traditional analog phone lines we never noticed it because there was never this delay introduced by the digital circuit. now that we have digital circuits which have an inherent delay in them, without a good DSP that cancels echo, we get echo. I notice that if the calling party is on a low quality phone, the echo is not nearly as bad, but when using a higher quality headset, I can hear much better, and unfortunately that means I can hear the echo better as well. I'm going to return these devices and try a different brand of ATA, and hope that it's not the same chipset and same DSP in next brand that I try. Maybe eventually there will be a firmware release that fixes this echo. (my Current firmware version: 1.3.3 (015)) Until then, do not buy unless you want your callers to have an echo.

Other Thoughts: makes a great gift for someone you really don't like.
when buying this or any other brand of ATA, get two so you can test them. callcentric has free accounts with free in-network calling, helped greatly for testing.

Mini Ball Head Ballhead 1/4
  • Verified Owner
  • Owned For: less than 1 day

Pros: works
good range of motion, tilts about 50 degrees in any direction
heavy duty metal construction

Cons: doesn't have as smooth of motion as a high quality ball head would have. it goes from tight to loose when you turn the adjustment screw, but there is no in-between, so getting a precise adjustment isn't as easy as it would be with a higher quality ball-head. A higher quality ball head mount would present some minimal resistance to motion even when the adjustment screw is loose, so that once you get it adjusted how you want it, it will be easier for you to clamp it down with the adjustment screw without the slightest muscle twitch throwing off the adjustment again.

gives off a strong smell of what I guess is poorly cured rubber. This smell is nauseating and is much stronger than the typical 'new product smell' that you can get with new products. In my experience when a product has this lousy rubber smell, the smell does not go away or get weaker with time. Not everyone responds to chemical smells the same so this might not bother all users of this product.

Digital Innovations AcoustiX 4330200 3 watts (1.5 per channel) 2.0 Speaker System
  • Verified Owner
  • Owned For: less than 1 day

Pros: they work

Cons: does not amplify quiet sound levels enough. Have to switch to headphones for some youtube videos. But videos with normal sound levels are plenty loud enough.

the base is angled, meaning, if you sit them upright, connected with the magnet connection, they are always on the verge of tipping over and they wobble around on your desktop a lot.

no headphone output jack.

power LED. Because I don't already have enough LEDs in my bedroom.

short cord that connects the two speakers. About 2 1/2 feet long. If that's as far as you can separate them, why have them separate at all.

Other Thoughts: the reviews that complain about the magnet strength are probably doing it wrong. i.e. if sitting horizontal, you can sit them on their sides, or on the 'feet'. If on the 'feet', then no, the magnet is not strong enough.

There is no need for the power switch on them.

If there was no power LED, and instead a headphone jack, and a switch to switch between speakers and headphone, that would be useful. If it's utility you're looking for, look elsewhere...
