[Asterisk-Users] Asterisk, Mobile Phones and PSTN

[Dhennys Pestana]

Does anyone ever tried to connect Asterisk to the public network using GSM
mobile phones connected through the USB (or Serial) port on the PC?

Is it possible to connect Asterisk to the PSTN with a GSM/GPRS card (PCI or
PCMCIA) connected to the PC?

In case it's possible, would I also be able to make more than one call
simultaneously (maybe even set up conferences) through the GSM network as I
can using my mobile phone?

Thanks in advance for any comments on this.
