[asterisk-users] GSM cellphone as cheap gateway?

[Vincent]

Hello

Even the cheapest GSM gateway I found for a simple SOHO server costs
over $300.

If possible, I'd rather have a local solution than use a remote VoIP
provider to have Asterisk make outgoing calls to the GSM network.

So... I was wondering if there are some entry-level cellphones that
can somehow be hooked up to a PC running Asterisk and used as an
el-cheapo GSM gateway?

Thank you.
