[asterisk-users] 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?

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.> > Is the customer buying a POTS line and splitting it the only other way? > > Thanks, > Matt > > > >-------------- next part -------------- An HTML attachment was scrubbed...

In fact the medical community is fearful of the legal beagles. These groups are really slow to change.

The mediatrix 4102s line kicks ass.
