Upgraded from TWC modem to Technicolor TC8717T modem/router from Spectrum and now my security system will not call out an alarm. It dials but the modem will not respond even though it’s using touchtone. The security company says it's because the system is using old touchtone protocol. Is there a converter that will go from old touchtone to what the TC8717T is looking for in a phone system protocol?

there is no such thing as old vs new touchcode. BTW, it's correctly called DTMFdialing.
Are you sure it's not set to do rotorary dial pulse? That can be an issue.
Is this single line and are you plugged into line one?
does a phone work on that line 1 jack?
