Hook Flash Tx
Method
Select the method for signaling hook flash events: None,
AVT, or INFO. None does not signal hook flash events. AVT
uses RFC2833 AVT (event = 16) INFO uses SIP INFO with
the single line signal=hf in the message body. The MIME
type for this message body is taken from the Hook Flash
MIME Type setting.
Default setting: None
Symmetric RTP Enable symmetric RTP operation. If enabled, the ATA
sends RTP packets to the source address and port of the
last received valid inbound RTP packet. If disabled (or
before the first RTP packet arrives) the ATA sends RTP to
the destination as indicated in the inbound SDP.
