<Hook_Flash_Tx_Method_1_>
<Hook_Flash_Tx_Method_2_>
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
<FAX_T38_Redundancy_1_>
<FAX_T38_Redundancy_2_>
Select the appropriate number to indicate the number of
previous packet payloads to repeat with each packet. Choose
0 for no payload redundancy. The higher the number, the
larger the packet size and the more bandwidth consumed.
Default setting: 1
<FAX_T38_ECM_Enable_1_>
<FAX_T38_ECM_Enable_2_>
Select yes to enable T.38 Error Correction Mode. Otherwise
select no.
Default setting: yes
<FAX_Tone_Detect_Mode_1_>
<FAX_Tone_Detect_Mode_2_>
This parameter has three possible values:
•
caller or callee
: The ATA will detect FAX tone whether
it is callee or caller
•
caller only:
The ATA will detect FAX tone only if it is the
caller
•
callee only
: The ATA will detect FAX tone only if it is the
callee
Default setting: caller or callee.
<Symmetric_RTP_1_>
<Symmetric_RTP_2_>
<Symmetric_RTP_5_> through
<Symmetric_RTP_13_>
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.
Default setting: no
<FAX_T38_Return_to_Voice_1_>
<FAX_T38_Return_to_Voice_2_>
When this feature is enabled, upon completion of the fax
image transfer, the connection remains established and
reverts to a voice call using the previously designated codec.
