No Answer (Remote Device Did Not Respond to Handshake)

The call connected and T.38 communication was established, but the remote device failed to respond to repeated attempts to handshake. This commonly occurs when using T38_INVITE to initiate T.38 media without the initial RTP audio phase. The timer is 35
seconds.


During phase B, the T1 timer expired while waiting for the remote unit to identify itself. This timer is 35 seconds.
