I have a 1998 DSC Power 832 that I installed new. I recently switched to Verizon Fios (fiber optic) from traditional copper. I am not 100% sure... but I think the problem started after the conversion.
My alarm is set in the pager dial mode. For years, my alarm successfully rang my cell phone when certain deactivation codes were input. (Daughter home, etc.)
Now, when I listen in from a handset, I get the "sorry the call can not be completed as dialed... or similar recording. If I lift another handset and listen to the ENTIRE DIALING ACTION, the alarm successfully calls my cell phone and it rings. If I don't lift a handset and listen, it won't connect. I unsuccessfully attempted to add 2 second pauses, using the "D" force dial tone, between digits and after the entire number... I am at a loss. I have had numerous people tell me that Fios should not make a difference. FIOS is not Voice Over Internet.
Please assist. Thank you in advance. Doug
