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

Subject: Re: [AFMUG] Voice Lines and Alarms

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.
