Out of curiosity, I have been trying to get a DMP com series cell dialer to work on this panel. I’m pulling my 12 VDC from the aux power, and have ran in my 2 Tel lines. The FACP, for some reason refuses to acknowledge the new dial tone. The new cell dialer is putting out around 28 on the Tel Lines. I’m wondering if that’s too low. Has anyone had a successful cell dialer on an EST? (I forgot to check the colts of the current tel service, which is still working, they just want to cancel the lines)
Thanks friends!
