GSM Channels

Asterisk Asterisk General
1

Hi Folks,

I’m researching PSTN cards and I see cards advertising that they support GSM Channels. Does this mean that my Asterisk PBX can be a local “cell tower” and make calls directly to cell phones or does it simply mean that I can get a SIM card and add a wireless channel to the existing PSTN wire channels?

Thanks for the help,

Chris.

You can get hardware that accepts a SIM card and acts like a handset with respect to the network.

There is also a third party open cell tower implementation, which acts as a SIP gateway, and is sometimes connected to Asterisk. However you will need a licence from your government to use that.
