A method of managing access to a push-to-talk-over-cellular (POC) talkgroup may include providing a control device configured to manage a first talkgroup, granting a first non-subscriber device access to the first talkgroup, and transmitting, from the control device to the first non-subscriber device, a first communication including a link to download a POC software application configured to access the first talkgroup. A method of managing access to a push-to-talk-over-cellular (POC) talkgroup may alternatively include providing a control device configured to manage a first talkgroup, providing a first subscriber device, transmitting, from the first subscriber device to the control device, first non-subscriber contact information associated with a first non-subscriber device, and granting the first non-subscriber device access to the first talkgroup.
