The majority of the parameters which are present in CTI Routing can be defined as default
value (Sys): the default value
will be the one setup by the CTISYS resource.
Use the following command to display the parameters of the resource; the d p ctisys ? command shows the meaning of parameters.

*** No NOT-H100 cards present or active *** These are the most frequently used parameters.
In the Router section, the
parameter ROUTING (Routing Management) allows to set
two kinds of CTI Routing functioning:
ROUTING:EN-BLOC. The CTI
Router waits to receive the complete number (from the line, the PABX
or other connected devices) before choosing the routing. The routing
table management is easier, but the disadvantage is that, at the end
of dialing, the user must press the “#” on the phone or
wait a time out of (generally) 5 seconds (see parameter
DIALT on CTI Ports) before the call starts.
ROUTING:PREFIX. The CTI
Router verifies the rule to match at the receipt of a single digit.
The configuration of the CTI Routing table is a bit more difficult and
delicate, but the advantage is that the user is not required to press
“#” on the phone or wait any time at the end of
dialing.
MAIL-FROM: the default sender of emails.
User demand must be considered when choosing the system.
Besides, the out dial tone is now played when a user picks up a POTS phone and dials the OUT-DIAL-DIGIT value (the OUT-DIAL-xx tone is played):
There are various parameters used to configure the out dial tone generation:
OUT-DIAL-TONE: enable/disable the outside dial tone generation [NO, YES].
OUT-DIAL-DIGIT: digit for outside selection ['0'..'9']
The section Last Calling number Service allows to choose two system parameters:
LCST: Last Calling number Service records timeout [NONE, 1..999 hour]
lcs-dir: Last Calling number Service Working directory path
The Last Calling number Service is useful if UMTS Box is installed, but it can be used with ISDN ports, CLUSTERS, as well as with SIP and IAX users.
The section CallTry allows to configure two parameters about call-try feature:
CALLTRY-TOUT: number of seconds between
retries [30..600 sec].
CALLTRY-NRTY: Number of retries
[1..30].
The most important parameters of EEC section are:
AECAcoustic Echo Canceller. When set to YES is enables for ALL the EEC channels the capability to cancel acoustic echo too. In normal telecom applications the AEC is not needed.
TAIL-BASEThe EEC can cancel echo in the range 0..128 msec. By specifying here a value greater than 0 the range is value+128ms. For example if TAIL-BASE is 256, the EEC is able to cancel echo between 256 and 384 msec.
![[Tip]](../images/tip.png) | Tip |
|---|---|
Use the following command to display the availability of Extended Echo Canceler (EEC): [14:25:58] ABILIS_CPX:The output of the above command is the following if Abilis is equipped with mixed ECC cards and non-ECC cards: [14:33:25] ABILIS_CPX: |
The section named Dsp firmwares and configurations for C6412 on QPRIX and PB44X allows to choose some parameters of the embedded vocoders.
TRANSPARENT, G711 and G729a vocoders are available as embedded vocoders through QPRIX and PB44X. The advantage is there's no need of additional DSP. The most important characteristics and limitations are:
echo canceller (EC) is available up to 32 ms but it can raise up to 128 ms in the version with the additional Octasic chip (EEC)
fax relay is not currently supported
Mixing cards with and without additional DSPsis not allowed, as well as mixing embedded vocoders and additional DSPs on the same card.
The choice of vocoders and echo canceller tail defines the number of available channels (ac). This number is automatically computed by Abilis once the type of vocoder and the echo canceller tail are set.
On the left side of the section there is the card type, this is required because the QPRIX and PB44X can be manufactured in 4 main types. On the right side there are 3 parameters to configure:
HDLC channels (named hdlc-b)
g.729a support (named g.729a)
echo canceller tail (named ec)
The ac value is automatically computed and shows the number of available voice channels (in the above example there are 18 channels for card type 2). Use the command s p ctisys card-type:2 g.729a:no to disable g729a support for card type 2. The number of available channels (ac) is automatically updated to 64.

dsp1-coderset:NORMAL dsp2e-fw:D2C4F6Into Audio compressors defaults
section there are the default values used in the system profile
(Sys).
When a compressed call between two Abilis is setup, the coder use
must be “negotiated”: the available coders set is defined in
CODERS field. The order of the list items defines also
the order of scan precessing.
CODERS:G.711,G.726,G.727,GSM6.10,Spirit,G.723.1,G.729A,Transp
In this section there are other interesting and very important parameters:
SC (Silence compression): enables or disables
the compression of the “silence” during compressed calls
for bandwidth use reduction.
FM-RELAY (Fax Data relay): enables or
disables the Fax Relay
management.
MAX-JBUF (Max. jitter buffer size): sets the
maximum compensating time of voice frames arrival variation (very
important on WAN realized on Internet connections).
| Tip |
|---|---|
As is well known, Internet lines are affected from latency and time arrival variation of frames caused by network congestion, timing drift, or route changes (this is the definition of jitter). When Internet lines are used for the VoIp application, it's fundamental to set the properly CTISYS parameter to obtain good results and good quality communication. The jitter buffer is managed by
Generally, on lines with a low time arrival variation of the
frames, good values can be:

In the POTS defaults section there are general parameters of CTI POTS Ports. The most important are:
CLIP (Caller Identification Presentation):
enables or disables the CLI on POTS ports (caller number
visualization) [NO:clip disabled, YES: clip enabled, EXT: the display
of the phone will show the address book name, if supported from the
phone];
SENSING: measures electrical parameters
currently present at the analogue interface.
Through CELL section, the administrator can configure some system parameter for UMTS BOX devices:
CELL-GAIN-IN: Input gain adjustment [MUTE,
-84..+6 dB]
CELL-GAIN-OUT: Output gain adjustment [MUTE,
-84..+6 dB]
CELL-CODEC-GAIN-IN: Audio-codec input gain
adjustment [MUTE, -126..+32 dB]
CELL-CODEC-GAIN-OUT: Audio-codec output gain
adjustment [MUTE, -59..+5 dB]
pdn-rxbuf: Size, in kbytes, of the PDN
receive buffer [10..255]
In the Tones and ringing patterns
section, the TONESET parameter allows to choose the
dial tone and other tones (i.e. alerting tone, busy tone…). By default, it
is set to ABILIS and it means that the dial tone is a
continuous one, but others are available: ITALY
(simulates the Italian Telecom dial tone) or USERDEF
(allows the user to customize the tones). The tones change by configuring
the sequence and the duration of TONEs and SILENCEs
(T1, S1,
T2...).

+------+------+------+-------------+------+Into Clock sources section it is possible to select where the port(s) take the ISDN clock signal. These are the available values:
INT: clock signal is generated by
Abilis;
ANYTE: clock signal is taken from one of the
TE ISDN ports that are present in the configuration; scanning from
left to right;
LIST: clock signal is taken from one of the
ports manually inserted into P1...P50 fields;
scanning from left to right.
Ctisys parameters are distributed to all the routings, but on each routing they can be manually changed.
