What you need is a single channel GSM gateway, like this one ...

http://www.mobilecomms-technology.com/contractors/gsm/eurotech1/eurotech11.html

which allows you to do something like:

[Asterisk]<=>[single FXO]------[GSM-GW]<=>(GSM network)

or if you have a need for many more channels, there is this one ...

http://www.mobilecomms-technology.com/contractors/gsm/eurotech1/eurotech14.html

which would be used in the following way:

[Asterisk]<=>[T1/E1]------[GSM-GW]<=>(GSM network)

this one not only supports multiple channels but it also has the
ability to use any of up to 4 SIM cards per channel. This means if
there is an outgoing call from your Asterisk system to a particular
GSM network, you can let the gateway automatically use a SIM card of
that network in order to get the lowest tariff.

As far as the GSM network is concerned, the gateway looks like one or
more ordinary mobile phones.


There are several other products in these categories. The cheapest I
have seen was about 150 USD (IIRC) for a single channel GSM to FXO
gateway.
