	Chapter 75. HowTo - CTI system

The SIP telephone can be an IP phone or a softphone running on a PC. It can be registered in the Abilis private or public side.

The configuration varies depending on the telephone is behind a NAT.

Enter into the Abilis control-program or open the configuration file with the Console configurator and type the following commands.

a res:ctisip or s act res:ctisip	Add the CTISIP resource. or If the resource already exists, set it active.
s p ctisip act:yes	Enable the CTISIP runtime functionalities.
a user:sip_phone pwd:sip_phone sip:yes	Add the username and password associated to the SIP telephone and enable it to SIP protocol.
s user:sip_phone sip-number:61	Configure the SIP telephone number.
s user:sip_phone sip-maxses-bid:4	Configure the maximum number of SIP bidirectional sessions.
save conf	Save the configuration.

On a working Abilis, a system restart is required to make the CTISIP resource running.

	Note
	It's possible to specify a FQDN in the `DOMAIN` parameter of the CTISIP resource. If the SIP user uses a local domain different from the one set in the CTISIP resource, you need to specify it in the User parameter `SIP-DOMAIN`. Usually you need to do it in this way when the Abilis has a public domain and the user need to access to it via the local area network.

	Note
	The previous configuration can be applied also when a SIP Proxy must register itself onto Abilis. In this case the proxy is a “normal” user like a SIP phone, but the `SIP-TYPE` parameter must be set up to `LOCAL-PEER` (e.g. s user:sip_proxy sip-type:local-peer).

	Tip
	For the softphones configuration, refer to Chapter 84, Softphones.

Enter into the Abilis control-program or open the configuration file with the Console configurator and type the following commands.

a res:ctisip or s act res:ctisip	Add the CTISIP resource. or If the resource already exists, set it active.
s p ctisip act:yes	Enable the CTISIP runtime functionalities.
s p ctisip max-sub:200	Configure the max number of subscriptions. (If we have 20 phones with BLF, and each monitors 10 phones, then we have 200 subscriptions.)
a user:sip_phone pwd:sip_phone sip:yes	Add the username and password associated to the SIP telephone and enable it to SIP protocol.
s user:sip_phone sip-number:61	Configure the SIP telephone number.
s user:sip_phone sip-maxses-bid:4	Configure the maximum number of SIP bidirectional sessions.
a res:http or s act res:http	Add the HTTP resource. or If the resource already exists, set it active.
s p http act:yes	Enable the HTTP runtime functionalities.
s p http sesnum-p:40	Change the number of HTTP sessions (If we have 40 phones with BLF).
s user:sip_phone http:yes	Enable the user sip_phone to HTTP.
a http rights path:/sys/opc/ user:sip_phone	Enable the user sip_phone to access the “Operator Panel Control” link.
a res:opc or s act res:opc	Add the OPC resource. or If the resource already exists, set it active.
s p opc act:yes	Enable the OPC runtime functionalities.
s p opc maxclients:40	Change the number of monitors that can require information from OPC (If we have 40 phones with BLF).
s user:sip_phone opc-monitor:sip	Configure the OPC monitored service for user sip_phone. (If this parameter is set to SIP, then the user monitors only SIP interfaces).
save conf	Save the configuration.

On a working Abilis, a system restart is required to make the resources running.

	Important
	BLF requires a separated licence in CPX and needs also SoftPBX licence as it's required by OPC.

75.9.2. How to register a SIP telephone onto Abilis when the telephone is behind a NAT

Enter into the Abilis control-program or open the configuration file with the Console configurator and type the following commands.

a res:ctisip or s act res:ctisip	Add the CTISIP resource. or If the resource already exists, set it active.
s p ctisip act:yes	Enable the CTISIP runtime functionalities.
a user:sip_phone pwd:sip_phone sip:yes	Add the username and password associated to the SIP telephone and enable it to SIP protocol.
s user:sip_phone sip-number:61	Configure the SIP telephone number.
s user:sip_phone sip-maxses-bid:4	Configure the maximum number of SIP bidirectional sessions.
s user:sip_phone sip-remote-nat:strict	Configure the NAT traversal method.
save conf	Save the configuration.

On a working Abilis, a system restart is required to make the CTISIP resource running.

	Note
	Users which are registered onto Abilis and that stays behind the same NAT, i.e. that presents themselves to the Abilis with the same IP address, can be configured (with `SIP-CPO`:`YES`) to exchange RTP directly each other, without transiting through the Abilis. In such a situation, if either puts on-hold, the other will receive RTP stream with the hold tone directly from the Abilis.

	Note
	It's possible to specify a FQDN in the `DOMAIN` parameter of the CTISIP resource. If the SIP user uses a local domain different from the one set in the CTISIP resource, you need to specify it in the User parameter `SIP-DOMAIN`. Usually you need to do it in this way when the Abilis has a public domain and the user need to access to it via the local area network.

	Note
	The previous configuration can be applied also when a SIP Server must register itself onto Abilis. In this case the proxy is a “normal” user like a SIP phone, but the `SIP-TYPE` parameter must be set up to `LOCAL-PEER` (e.g. s user:sip_proxy sip-type:local-peer).

	Tip
	For the softphones configuration refer to Chapter 84, Softphones.
