<Preferred_Codec_1>, <Preferred_Codec_2>
<Second_Preferred_Codec_1>, <Second_Preferred_Codec_2>
<Third_Preferred_Codec_1>, <Third_Preferred_Codec_2>
|
Up to three codecs to be used for all calls from the specified line/handset, listed order of preference. The actual codec
used in a call depends on the outcome of the codec negotiation protocol. Select one of the following: G711u, G711a, G726-32,
G729a, or G722.
Default setting for Preferred Codec: G711u
Default setting for Second and Third Preferred Codec: Unspecified
|
<Use_Pref_Codec_Only_1>
<Use_Pref_Codec_Only_2>
|

select no.
Default setting—no
|
<Use_Remote_Pref_Codec_1>
<Use_Remote_Pref_Codec_2>
|
To use the preferred codec specified by the remote peer, select yes. Otherwise, select no.
Default setting:
|

<Codec_Negotiation_2>
|
Specify the codecs for codec negotiation:
Default or List All.
Default setting—Default
|

|
Select the appropriate setting for the threshold: high, medium, or low.
Default setting—medium

|
To enable detection of the fax Calling Tone (CNG), select yes. Otherwise, select no.
Default setting—yes
|
<FAX_Passthru_Codec_1>
<FAX_Passthru_Codec_2>
|
Select the codec for fax passthrough, G711u or G711a.
Default setting—G711u
|
<FAX_Codec_Symmetric_1> through <FAX_Codec_Symmetric_2>
|
To force the ATA to use a symmetric codec during fax passthrough, select yes. Otherwise, select no.
Default setting—yes
|
<DTMF_Process_INFO_1>
<DTMF_Process_INFO_2>
|
To use the DTMF process info feature, select yes. Otherwise, select no.
Default setting—yes
|
<FAX_Passthru_Method_1>
<FAX_Passthru_Method_2>
|
Select the fax passthrough method: None, NSE, or ReINVITE.
Default setting—NSE
|
<DTMF_Process_AVT_1>
<DTMF_Process_AVT_2>
|
To use the DTMF process AVT feature, select yes. Otherwise, select no.
Default setting—yes
|
<FAX_Process_NSE_1>
<FAX_Process_NSE_2>
|
To use the fax process NSE feature, select yes. Otherwise, select no.
Default setting—yes
|
<DTMF_Tx_Method_1>
<DTMF_Tx_Method_2>
|
Select the method to transmit DTMF signals to the far end: InBand, AVT, INFO, or Auto. InBand sends DTMF by using the audio
path. AVT sends DTMF as AVT events. INFO uses the SIP INFO method. Auto uses InBand or AVT based on the outcome of codec negotiation.
Default setting—Auto
|
<FAX_Disable_ECAN_1>
<FAX_Disable_ECAN_2>
|
If enabled, this feature automatically disables the echo canceller when a fax tone is detected. To use this feature, select
yes. Otherwise, select no.
Default setting—no
|
<DTMF_Tx_Mode_1>
<DTMF_Tx_Mode_2>
|
DTMF Detection Tx Mode is available for SIP information and AVT. Options are: Strict or Normal.
Default setting—Strict for which the following are true:
The minimum and maximum duration thresholds are:
-
strict mode for AVT: 70 ms
-
normal mode for AVT: 40 ms
-
strict mode for SIP info: 90 ms
-
normal mode for SIP info: 50 ms
|
<DTMF_Tx_Strict_Hold_Off_Time_1>
<DTMF_Tx_Strict_Hold_Off_Time_2>
|
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: 70 ms
|
<FAX_Enable_T38_1>
<FAX_Enable_T38_2>
|
To enable the use of ITU-T T.38 standard for FAX Relay, select yes. Otherwise select no.
Default setting—no
|
<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>
|
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. Select yes to enable this feature, or select no to disable it.
Default setting—no
|
<Dial_Plan_1>
<Dial_Plan_2>
|
The allowed number patterns for outbound calls. The default dial plan script for the line is as follows: (*xx|[3469]11|0|00|[2-9]xxxxxx|1xxx[2-9]xxxxxx|xxxxxxxxxxxx.)
