Im a Asterisk newbie, i want to setup a simple PBX with inbound and outbound calling. I have zeroed on "GSM Asterisk AX4G card" as the telephony card.
While purchasing this card on their website they also ask to select GSM Module (apart from the GSM AX4G card). What is this GSM Module? This card can be viewed at Click here to view the card
Is this card reliable? Can i deploy a simple PBX with a single channel GSM card?
Apologies if my queries are too basic, Im newbie here please bear with me.
Thanks in advance!
