I knew this was a gamble because I have an ADT security system which was setup to use my landline.
Tonight I hooked up my ADT system to the ATA that came with my sonic account, and it appears that I am unable to get any communication through at all. I have read forum posts about changing the default codec setting, but it appears that this setting is no longer accessible from member tools. And the ATA itself appears to be locked down by Sonic so I can't change its settings.
When I initiate a communication test on my security system keypad, I see a toll free number being called repeatedly in my Sonic call history. But as nearly as I can tell, the communication is failing.
All previous posts on this topic were from 2015 and 2016. So I am curious if anything has changed in terms of compatibility with ADT as well as options available for sonic end users to tweak.
I know that ADT has a wireless option, as do vivint and simplysafe. I'd rather not go that route but will if I have to.
I already have the modem and ATA plugged into a UPS in case of power outage BTW
Any guidance here, especially experience that supercedes the comments from 2015, would be appreciated.
