75.4.1. How can I manage alternative CTI routings?

If the called phone is busy or not responding, the call is forwarded to the next routing if in the current one the NEXT parameter is set to TRANSFERT.

When the parameter LAST is set to BUSY or NOANS or OTHER the routings can match only if the last failure reason matches the one specified in LAST.

Note that:

Routing with LAST <> ANY can match only if a previous routing failed; they will never match as first routing;
When a routing with LAST <> ANY fails, the original failure reason isn't updated.

For example:

PR:0 is main call.
If PR:0 fails with BUSY reason PR:1 is executed, e.g. call sent to a colleague.
If PR:0 fails with NOANS reason PR:2 is executed, e.g. call sent to the PBX main operator.
If PR:0 fails with OTHER reasons (other than BUSY and NOANS) PR:3 is executed, e.g. call sent to a DISA group that plays a message telling that call could not be delivered.

75.4.2. How does Round Robin scanning method work in the CTI Port Group?

If in a CTI group the S parameter is set to R, the incoming calls are directed towards the CTI ports in a circular manner; e.g. the first call is forwarded to the port set in P1 parameter, the second call is forwarded to the port set in P2 parameter, etc.

If a port is busy or not responding, the call is forwarded to the next port if the R parameter is set to UN (unconditional). In case of “no answer” the call is forwarded to the next port after the time interval set in the T301 parameter; in case of “busy” the call is immediately forwarded to the next port.

For example:

----------------------------------+------------------------------------------------

	Note
	If the `T301` parameter is set to the default value (180 sec.), the call isn't forwarded to the next port.

75.4.3. How can I change the POTS number length?

By default, the POTS port numbers are 2 digits long; it's possible to change their length by modifying the POTS-NUM-LENGTH parameter in the CTISYS resource (available values are: [1..20]). For example:

s p ctisys pots-num-length:3	Change the `NUM` parameter length to 3.
save conf	Save the configuration.
init ctisys	Initialize the CTISYS resource.

75.4.4. How can I activate the Caller Identification Presentation (CLIP) on POTS ports?

Set the CLIP parameter to YES in the CTISYS resource.

s p ctisys clip:yes	Activate the Caller Identification Presentation.
save conf	Save the configuration.
init ctisys	Initialize the CTISYS resource.

	Tip
	Refer to this paragraph to know more about CLIP parameter.

75.4.5. How can I manage the Calling Line Identification (CLI) for outcoming calls?

Calling Line Identification can be statically managed in the CGO parameter in CTI Routings:

CGO:# : Set an empty information element. An empty information element in most cases is removed.

In the alternative, if the call is incoming from a POTS port which is configured with SS:YES and SS-PRES-CG:YES, it's possible to force CLIR/CLIP typing the following codes:

*60#<number-to-dial>: make a call to <number-to-dial> hiding the calling number;
*61#<number-to-dial>: make a call to <number-to-dial> presenting the calling number.

	Caution
	In this case the `CGO` parameter in the CTIR routing must not be set to `#`.

75.4.6. Why during a call do I hear a FAX handshaking?

During the compressed call, the calling or called phone intercepts the handshaking of a FAX located near the phone. The DSP used by Abilis identifies this signal as a request of FAX transmission and starts to simulate the FAX modulation.

The possible solutions are:

Mute the fax volume;
Disable the fax relay feature (FM-RELAY:NO in the setting of CTISYS resource, or FMRLY:NO in the specific CTIR routings).

	Tip
	Refer to chapter Section 46.12.3.5, “Fm-relay parameter”.

75.4.7. How can I view the maximum number of simultaneous calls supported by Abilis?

To view the maximum number of simultaneous calls supported by Abilis type the command: d d ctiac or d de ctiac for the extended mode.

For example the following Abilis allows up to 8 simultaneous calls.

75.4.9. How can I change the volume of a compressed call?

It's possible to modify the OUT-GAIN parameter in the CTISYS resource. For example:

s p ctisys out-gain:+3	Change the output gain in the range [MUTE, -31..+31 dB].
save conf	Save the configuration.
init ctisys	Initialize the CTISYS resource.

For the phones connected to POTS cards, it's possible to modify the OG parameter in the specific CTI Routing. For example:

s ctir pr:5 og:+5	Change the output gain in the range [SYS, MUTE, -31..+31 dB].
save conf	Save the configuration.
init ctir	Initialize the CTI Routings.

75.4.10. How many VoIP channels are used, depending on the call's source and destination?

Codec used by the call coming from VoIP telephones in the LAN	Abilis routes the call toward	VoIP channels occupied	Bandwidth occupied by each channel (Kbit/s)
SIP Codec G.711	Telecom ISDN network	1	64
SIP Codec G.729	Telecom ISDN network	1	64
SIP Codec G.711	Abilis over ISDN network	2	9
SIP Codec G.729	Abilis over ISDN network	2	9
SIP Codec G.711	VoIP provider with G.729	2	32
SIP Codec G.729	VoIP provider with Abilis Codec	2	30 the first call, 9 the others calls
SIP Codec G.711	VoIP provider with G.729	0	32
SIP Codec G.729	VoIP provider with Abilis Codec	2	30 the first call, 9 the others calls
IAX2 Codec G.711	Telecom ISDN network	1	64
IAX2 Codec G.729	Telecom ISDN network	1	64
IAX2 Codec G.711	Abilis over ISDN network	2	9
IAX2 Codec G.729	Abilis over ISDN network	2	9
IAX2 Codec G.711	VoIP provider with G.729	2	32
IAX2 Codec G.729	VoIP provider with Abilis Codec	2	30 the first call, 9 the others calls
IAX2 Codec G.711	VoIP provider with G.729	0	32
IAX2 Codec G.729	VoIP provider with Abilis Codec	2	30 the first call, 9 the others calls

	Note
	1 DSP manages 4 channels.

75.4.11. What happens if a call fails with the “CAUSE:FF B4 (CPX,Loop)”?

When a call ends with the disconnection code CAUSE:FF B4 (CPX,Loop), Abilis blocks the calls which enter and exit from the same ISDN port, when in the CTI Routing the POI parameter is set to *.

To enable the loop, you must add a CTI Routing with POI:<port_number> and OUT:<port_number> (e.g. POI:32, OUT:32) before the CTI Routing with POI:*.

75.4.12. How can i configure SIP multialerting?

SIP multialerting is implemented. To configure SIP multialerting is need to create heterogeneous groups of SIP phones.

	Tip
	Refer to chapter Section 72.5, “How to configure a multicast group of SIP phones”.
