Configuring Voice Configuring Voice Settings 4 Field Description DTMF Tx Strict Hold Off Time This parameter is in effect only when "DTMF Tx Mode" is set to "strict," and when"DTMF Tx Method" is set to out-ofband; i.e. either AVT or SIP-INFO. The value can be set as low as 40 ms. There is no maximum limit. A larger value will reduce the chance of talk-off (beeping) during conversation, at the expense of reduced performance of DTMF detection, which is needed for interactive voice response systems (IVR) Default: 40 ms FAX Enable T38 To enable the use of ITU-T T.38 standard for FAX Relay, select yes. Otherwise select no. Default setting: Yes 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 FAX T38 Redundancy 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 Select yes to enable T.38 Error Correction Mode. Otherwise select no. FAX Tone Detect Mode 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.

DTMF Tx Strict Hold
Off Time
This parameter is in effect only when "DTMF Tx Mode"
is set to "strict," and when"DTMF Tx Method" is set to
out-ofband; i.e. either AVT or SIP-INFO. The value can
be set as low as 40 ms. There is no maximum limit. A
larger value will reduce the chance of talk-off
(beeping) during conversation, at the expense of
reduced performance of DTMF detection, which is
needed for interactive voice response systems (IVR)
Default: 40 ms
FAX Enable T38
To enable the use of ITU-T T.38 standard for FAX
Relay, select yes. Otherwise select no. Default
setting: Yes
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
FAX T38 Redundancy
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
Select
yes
to enable T.38 Error Correction Mode.
Otherwise select no.
FAX Tone Detect Mode
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.
