> Hi,
> 
> In push to talk services: Based on who is available, the user can simply push a button and start a Push-To-Talk dialog in a walkie-talkie or chat room-like mode. 
> Whenever a user presses a button, he can start speaking instantly. Terminator need not answer this call.
> 
> If we assume that sessions are maintained in PTT through SIP, then whenever a user presses a button, an invite message is sent to the terminator. Then without getting an 200OK message how can a session be established between the two parties?
