Abstract
Methods and apparatus for initiating a PTT call from a caller client device to a recipient client device. The methods and apparatus register the caller client device with the PTT system, wherein caller data identifying the caller client device is transmitted to the PTT system; store the caller data; generate, at the caller client device, a channel request message that includes channel allocation data and call invite messaging information; transmit the channel request message to the PTT system; parse the call invite messaging information from the channel request message; generate a call invite message based upon the call invite messaging information and the stored caller data; and establish the PTT call between the caller client device and the recipient client device based upon the call invite message. Additionally, the call invite messaging information includes an identification number and not the URI of the recipient client device.
