A method of facilitating push-to-talk (PTT) communications between a server device and a client device using SIP-based messaging, the server device being in communication with a media server. The method includes receiving in the server device from the client device a SUBSCRIBE message for subscription to a push-to-talk group, the SUBSCRIBE message including media information of the client device, storing in the server device the media information of the client device, and sending from the server device to the client device a NOTIFY message, the NOTIFY message including media information of the media server for storage by the client device.
