asterisk users - Oct 2005 - "GSM cards" / "mobile phone cards" for Asterisk?

I was wondering if there is something like that on this Earth:

Some of our users are "mobile users" - they are rarely in one place
for
longer than 15 minutes.
They use mobile phones a lot.

 From our mobile operator we have an offer which allows us to call for 
free between our mobile phones.

So the idea is to put a SIM card inside the Asterisk box, equipped with 
a special card, a card which would be a mobile phone really.

This would allow all office users to reach our mobile users without the 
need of buying additional phones for the office users.
Office users would call Asterisk over IAX, and asterisk would call 
"mobile users" using a free GSM/mobile.

Does anyone have an idea if such cards exist, and if so, if they work 
with Asterisk?

There are a number of places that sell GSM gateways (which is what you're
referring to). What I've yet to see are GSM gateways for small business
users that take only one SIM card. Most of the ones I've seen are larger
units designed for 4-16 SIM cards.

If anyone knows of smaller-scale units that work on GSM900 and 1800, I'd
also love to hear about them.

You can get "Fixed" Cell units... basically a Cell Phone which
provides a Trunk
line instead of screen and keypad. This looks then like an analogue trunk line.
I believe that there is an Italian PCI card that has 4 cell units built
into it. I believe that such units can also plug into an Ethernet and
run SIP.

or - Wait for the Sony Ericsson P990i cell phone which comes with Wifi -
and stick on a SIP client.. and run wireless.

Tomasz,

 I'm from Brazil, and we are using here a solution that is based on a box 
where we can connect a GSM cellphone and use this directly to a phone or PBX 
extension.
 I think that you can use some Digium's card (FXS or FXO) on your server, 
connect this GSM box there, and route your cellphone calls through this box.

 There are boxes with just one channel and others up to six channels.
 They have a lot compatibilities with the most common cellphones.

 Take a look to this site: 
http://www.zenitetecnologia.com.br/english/index.jsp
 Zenite is one of the best companies that build this boxes here in Brazil.

 I hope that I could help you.

looks interesting.

do you know by chance how much such a single-cell box cost (more or less)?

You might want to investigate a Nokia 22
(http://europe.nokia.com/nokia/0,8764,56024,00.html). This provides a single GSM
line which is interfaced to the PBX by an anlogue trunk/extension. From memory
they cost around ?100-150. I am going to revisit this as a solution to our ever
increasing PSTN-GSM call spend as soon as we have our Asterisk PBX in place.
