Hi,<br><br>Using SIP methods and options, is there any way for a callee to send the caller a short text message when the call is establishing ?<br><br>Scenario is :<br><br>Alice and Bob's SIP phones are registered to an Asterisk server.
<br>Alice calls Bob : an INVITE message is sent to Bob's phone<br>Bob is replying : a 200 OK message is sent back to Alice with a short text included ("Welcome to BoB Corporation")<br>Alice's phone acknowledges (ACK) and displays "Welcome to BoB Corporation" somewhere beside the dialed digits (Bob's number).
<br><br>Regards<br><br>
