A method of communication includes receiving a request to initiate a push-to-talk/instant messaging exchange from a push-to-talk device (110). A determination is made in order to ascertain if an instant messaging device (114) is available to partake in the push-to-talk/instant messaging exchange. If the instant messaging device (114) is available, the push-to-talk device (110) is notified that the push-to-talk/instant messaging exchange has begun. Voice packets are received from the push-to-talk device (110) after a push to talk button is pressed and released. The voice packets from the push-to-talk device are converted to text packets. Then, the converted text packets are transmitted to the instant messaging device (114). The method further includes determining whether the push-to-talk device (110) is blocked by the instant messaging device. If the push-to-talk device is not blocked, text packets are received from the instant messaging device and converted to voice packets. Further, the converted voice packets are transmitted to the push-to-talk device (110).
