asterisk users - Jun 2015 - FXS Solutions for modems and other non jitter tolerant devices

In the past we have used Adtran Atlas 550's to break out FXS ports for
devices like modems.  The great thing about the 550 is that internally it
is all TDM so there is absolutely zero latency.

We are able to use ATA's for faxes and analog phones but devices that use
modems, they fail 99.99% of the time when using an ATA.

We tried to migrate to TA908 devices; they have FXS ports built into the
unit.  Unfortunately the FXS ports are just ATA's off of Asterisk, no
different than a SPA2012 unit.

The 550 is getting long in the tooth and very expensive for a few FXS
ports, what are you folks doing when someone has a need?  It can be a modem
for the power company to read the meter, a postage machine that needs to
get more postage, an alarm system,etc.

Is the customer buying a POTS line and splitting it the only other way?

Thanks,
Matt

Finding less and less need for analog circuits. Alarm -> envisalink, 
postage machine -> ethernet based, pos terminal -> ethernet.

Fax is really the only need recently, and even that has alternatives 
like emailing scans that most people prefer now.

The legal and medical communities still seem to prefer faxing, in the (
mistaken? ) belief that it is more secure. In fact the medical community is
fearful of the legal beagles.

These groups are really slow to change.
At least in the USA

The mediatrix 4102s line kicks ass.
