I have dry loop dsl--->modem\router-->ooma hub-->uniden wireless phone hub (2 handsets). No wall jacks used.
Also have modem\router--->2 computers (ethernet and wifi).
I keep getting dropped calls daily - mostly as soon as I pickup. Some after being into the call 10-15 mins get dropped.
Voice quality is fine (no echo or disturbances). Ooma support asked me to do bunch of tests and setup upstream QOS but that didn't help either. So I removed it.
Some additional points:
>I use the internet quite a bit, and have never seen slowdowns during the day - or on any of the voip or bandwidth tests.
>The calls get dropped even when there is no net usage anywhere in the house.
>I keep hearing a click sound from the hub every 10 mins or so (like it has a relay switch inside or something).
>Previously had Vonage - same setup - with no issues whatsoever (other than price).

Any help is greatly appreciated.. thanks!!
My modem was retraining every few days (sometimes a few times per day) and briefly interrupting Internet service which wasn't noticed by web surfing, but it instantly dropped my VOIP calls (and may cause your Ooma backup modem to click).
When I pointed out the logs to AT&T, they did some line tests followed by digging in a neighbor's yard, after which the DSL modem logs showed uninterrupted service with an occasional retrain in the middle of the night every several months, which AT&T said was normal and probably due to their maintenance efforts.
I later switched to a Cable modem and recently switched to AT&T U-verse. Both have been solid with clean logs. I also still have a Siemens 4100 DSL modem at my other house which is solid.
Hopefully, this will help you. There's also some great debuggers on this forum, that will probably jump in.
Otherwise the modem will disconnect when it thinks there is no traffic.

Friends don't remember what Landline Integration was or why we did it.
