1. phone plugged directly into the telco unit -- no change
2. different cord to power - no change
3. moved telco to different location -- no change
4. *99 to see if that helped - did not
My internet service is top with 12Mbs download and 2Mbs upload with zero jitter.
The telco unit has zero for QOS.
Again, the problem did not exist using the Vonage device.
I am inclined to think the telco unit has a poor design for shielding since posts say the hub system does not have this problem.
I have this same problem, but it's more of a buzzing noise.oom101 wrote:There seems to be some wooshing on calls using Hub and Telo, but if you consider it a hum, then it turns out that the Telo has an electronic "brick" power plug that is light weight and electronic, and can take 100V-240V, but the Hub has a very heavy transformer plug in. Makes me think some Telo power cords might be causing noise? Have heard others complain about radios playing, etc. I have both units, and there is some slight background noise, like wind blowing a little, but it is not bad. Maybe they could swap out your power cord?
