A system and method to leverage Web Real-Time Communication (WebRTC) for implementing Push-to-Talk (PTT) solutions. One or more servers interface to a communications network to perform advanced voice services for one or more wireless or wired user devices, wherein the advanced voice services include a two-way half-duplex voice call within a group of the user devices comprising a PTT call session. At least one of the user devices communicates with at least one of the servers during the PTT call session using a WebRTC connection, and at least the media streams for the PTT call session are transmitted between the server and the user device using the WebRTC connection.

Request information received by a call handler system specifies multiple acceptable call connection encoding options or formats for communicating with a caller. The call handler system forwards the multiple acceptable call connection encoding options to a called destination. The called destination responds with a selection of a first call connection option from the multiple call connection options. The call handler system selects a second call connection option for providing a ring-back tone to the caller while waiting for the called destination to answer his phone. During the wait, the call handler system provides a ring-back tone to the caller via the second call connection encoding option. Upon detection of the called destination answering his phone, the call handler system discontinues playback of the ring-back tone and notifies the caller to communicate with the called destination via the first call connection encoding option as selected by the called destination.
