[Asterisk-Users] Siemens GSM terminal with Wildcard FXO

[Chad Wicker]

Well now that you mention it, I have Used a Telular GSM Fixed Wireless
Terminal using asterisk to both place and receive bulk calls.  I was
using it to test the unit out, though I personnally wouldn't suggest the
terminal ( seems like it is very buggy) it does seem to work.  There are
several options as it goes depending on the scale of your
implementation.  One was to look at it would be to use a FWT to connect
to your FXO card or a T1 via a channelbank, a good solution but very
clunky.  one of the more clever ideas is the Chan_bluetooth which would
wirelessly connect to your phone.  I am interested in the possibility of
connecting multiple phones using this method.  If you are interested in
high Density, There are GSM to T1/E1 channel banks out there but I am
just begining to explore them.  Please keep me informed of any success
you may have in this as I am very interested.  I work for a new GSM 850
provider here in the states.

Hi Jafar,

You want to look at Fixed Cellular Telephones (FCTs) like the Nokia
Premicell or the Ericsson F251.  As I understand it these present a
PSTN interface which you can plug into an FXS interface.
