They are converting to Cellular, sms, ip equipment, and wireless. There are even conversion units that act like the modem receiving and transmit over wireless or IP.

Most telcos no longer have copper pots.  I wonder what the alarm and elevator companies are doing as pots is gone from almost everywhere.

Comcast voip isn't going over the internet. Theirs runs close to a good quality landline with no jitter on their internal network. So it can handle data from alarms.

Regular voip going over the internet is good enough for voice but not usually good enough for data.

Our policy for phone lines is we only support voice. We don't support anything that requires data or life safety applications like fax, alarms, elevators, fire alarms, etc. There are efax solutions for old school fax machines but it's not a normal voip line.

    I just switched a business customer over from Comcast. They had
    one voice line and data. After the number ported their alarm
    stopped working. The alarm company is telling me that their system
    will work over Comcast's voip, but won't work over most other
    providers, including AT&T landlines.

    A couple of things here:

    You can have a data stream for an alarm going out a voice line
    that is actively used for it's intended purpose?

    This can, in some cases, be a VoIP line?

    They are trying to hit this account up for $1700 to switch over to
    a cellular / IP system.
