[Note]Note

This command displays only the parameters related to enabled driver; if you want to see all the user parameters type the d usere:sip_user command.

Meaning of the most parameters:

SIP

Enables/disables SIP service for the user [NO, YES].

SIP-TYPE
  • PHONE: The user is a SIP client of Abilis, typically a phone or a softphone and the SIP-DOMAIN specifies the local domain of Abilis. if the SIP-HOST and/or SIP-UDP-REMPORT (SIP-TCP-REMPORT) are dynamic the the client has to register on Abilis.

  • LOCAL-PEER: The user is a SIP PEER as Abilis and SIP-DOMAIN specifies the local domain of Abilis. Calling and Called numbers are both passed to the user. Usually the user registers on Abilis or has a static SIP-HOST and SIP-UDP/TCP-PORT.

  • SERVER: The user is a SIP server for Abilis and SIP-DOMAIN specifies the remote domain. Usually the Abilis registers on this user.

  • REMOTE-PEER: The user is a Peer as Abilis and SIP-DOMAIN specifies the remote domain.Calling and Called numbers are both passed to the user. Usually the Abilis registers on this user.

    [Note]Note

    The user may also be a PEER, it means a device that has the same SIP role of the Abilis and the calling number has to be passed unchanged.

SIP-DOMAIN

Domain of the called SIP UA server in outgoing calls.From 0 up to 64 characters in the range ['0'..'9', 'a'..'z', '-', '.' ] or SYS. Case is not preserved. SYS means to use DOMAIN value in CtiSip configuration and it is allowed only for SIP-TYPE equal to PHONE or LOCAL-PEER.

SIP-HOST

IP address of the SIP host [DYNAMIC, 1-126.x.x.x, 127.0.0.1, 128-223.x.x.x] or FQDN host name of max. 64 characters in the range ['0'..'9', 'a'..'z', '-', '.' ]. FQDN name is forced to lower case. Domain and Host may differ, because SIP registrar server may be different from SIP proxy; normally proxies and SIP registrar server are co-located [DYNAMIC: IP is not known in advance, it is known after the user executes the registration; 1.0.0.0-126.255.255.255, 128.0.0.0-223.255.255.255: remote IP is known in advance; calls and registrations are performed and accepted only with this IP].

SIP-TCP-REMPORT

TCP port on which the remote user is listening; Abilis outgoing TCP calls for this user will be sent to this port [DYNAMIC: the port is learned from incoming registration; 1..65535: calls and registrations are performed and accepted only with this port]. Only for SIP-HOST not equal to DYNAMIC.

SIP-UDP-REMPORT

UDP port on which the remote user is listening; Abilis outgoing UDP calls for this user will be sent to this port [DYNAMIC: the port is learned from incoming registration; 1..65535: calls and registrations are performed and accepted only with this port]. Only for SIP-HOST not equal to DYNAMIC.

sip-udp-locport

UDP port on which the Abilis is listening for this user [SYS, AUTO, 1..65535] . The default value is SYS and refers to the port parameter udp-locport. AUTO and a port different from the one configured in SIP port parameter "udp-locport" may be assigned only to SIP-TYPE REMOTE-PEER or SERVER. Note that this is a lower cased parameter, it means that an Abilis CPX reboot must be performed to apply changes, in detail you need to save the configuration ( command save conf ) and restart the Abilis ( via the command warm start ).

SIP-SRCADD

Source IP address for outgoing connections [R-ID: the source IP address of the outgoing datagrams will be set to the current RouterID value; OUT-IP: the source IP address of the outgoing datagrams will be set on the base of the output IP interface; 1-126.x.x.x, 128-223.x.x.x: the source IP address of the outgoing datagrams will be set to the selected value; Ip-nnn: use the current IPADD of the specified IP resource; SYS: uses the value in SRCADD parameter in CTISIP resource].

SIP-PROT

Transport protocol used to receive/send calls for this user [TCP, UDP].

SIP-IP-PERMIT

Allowed IP address of the SIP user. One or two IP addresses in the range [1-126.x.x.x, 127.0.0.1, 128-223.x.x.x] separated by ':' (colon) or the name of an IP/IR list or "*"..

SIP-MAXSES-BID

Maximum number of simultaneous bidirectional sessions [0..255].

SIP-MAXSES-IN

Maximum number of simultaneous reserved input sessions [0..255].

SIP-MAXSES-OUT

Maximum number of simultaneous reserved output sessions [0..255].

SIP-NUMBER

User number that identifies the resource for call routings. From 0 up to 20 characters in the range [0..9, *] optionally preceded by TON [u, i, n, o, s, h, c] and/or NP [x, e, d, t, l, p] attributes.; if this number is not null, it is used to route calls to the user.

SIP-ADDRBOOK-NUM

Address book SIP phone number assigned to this user. "#" or "SIP-NUMBER" or from 1 up to 20 digits ['0'..'9'], optionally preceded by TON [u, i, n, o, s, h, c] and/or NP [x, e, d, t, l, p] attributes or 'macro'. (E.g.: 0'SIP-NUMBER' or 123'SIP-NUMBER.s2' or 'SIP-NUMBER'99)

SIP-CG-NUM

Calling number to use for calls coming from the user. The parameter accepts from 1 up to 20 characters in the following range: [AUTO: enforces caller id information element equal to SIP-NUMBER; [0..9]: enforces the content with these exact digits; [0..9]*: replaces first specified digits and passes the remaining transparently; *: passes calling address information element transparently; #: removes calling number information element; ##: enforces the presentation restricted: the calling number is sent empty; ##[0..9]: enforces the presentation restricted: the calling number is sent with these exact digits; ##[0..9]*: enforces the presentation restricted: the first specified digits are replaced and the remaining are passed transparently; ##*: enforces the presentation restricted: the calling number is sent transparently].

SIP-FWD-CG-NUM

Indicates how the calling number is managed in unconditional call transfers and call forwarding [CALLER: the calling number of the original call is passed to the new recipient; USER: the calling number of the SIP user performing the action is passed to the new recipient].

SIP-CTIP-TYPE

CTIP type [SYS, USER, NET-PRIVATE, NET-PUBLIC].

SIP-RG-IN

Enable/disable management of incoming redirecting [SYS, DISABLE, ENABLE]. Set such parameter to allow the redirecting number coming from SIP to be passed to the CTI rouer

SIP-ROUTE-BY-SD

Allows routing using subaddress called field [NO, YES]. Calls from CTIR and directed to SIP users are first directed to the user with a USERNAME equal to what is specified in Subaddress Called; if such user does not exists, or the user disallows SIP-ROUTE-BY-SD, the call is routed using standard CTISIP table matches.

49.2.1.1. CTISIP INVITE messages

A caller sends this message to request that another endpoint join a SIP session, such as a conference or a call. This message can also be sent during a call to change session parameters.

Meaning of the most important parameters:

  • Request-URI: The Request-URI header field contains URI of the next hop of the message.

  • From: The From header field identify initiator of the invitation

  • To: The To header field identify recipient of the invitation

In a SIP-TYPE:PHONE the INVITE from 101 to the user sent by the abilis contains:

  • Request-Uri: test@80.80.80.80 (where test is the sip user and 80.80.80.80 is the IP address of the device)

  • From: 101@abilis.voip.net (where abilis.voip.net is the local domain)

  • To: test@abilis.voip.net

In a SIP-TYPE:LOCAL-PEER the INVITE from 101 to 0123456 sent by the abilis contains:

  • Request-Uri: 0123456@80.80.80.80 (where 0123456 is the called number and 80.80.80.80 is the IP address of the user)

  • From: 101@77.77.77.77 (where 77.77.77.77 is the IP adress of the Abilis)

  • To: 0123456@80.80.80.80

In a SIP-TYPE:SERVER the INVITE to 0123456 sent by the abilis contains:

  • Request-Uri: 0123456@sipserver.com (where 0123456 is the called number and sipserver.com is the FQDN of the server)

  • From: abilis@sipserver.com (where abilis is the SIP remote user and sipserver.com is the remote domain)

  • To: 0123456@sipserver.com

In a SIP-TYPE:REMOTE-PEER the INVITE from 101 to 0123456 sent by the abilis contains:

  • Request-Uri: 0123456@sipserver.com (where 0123456 is the called number and sipserver.com is the FQDN of the remote peer)

  • From: 101@77.77.77.7 (where 77.77.77.77 is the IP address of the Abilis)

  • To: 0123456@sipserver.com

49.2.2. CTISIP translation table

This table contains relations between a SIP-number (or a prefix, when * is included in the number) and a SIP-user. Calls which CTIR forwards to CTISIP finds the destination user by matching the called number (matching between the CDO field of the CTI routing and the CDI field of this table).

When SIP-CG-NUM:AUTO in the Users table, calls from CTISIP to CTIR will have:

  • the callerid provided by SIP user validated in the CTISIP translation table;

  • the SIP-number set in user service.

In case of validation failure the callerid will be overwritten with the value configured in the SIP-number of the user table (*, as wildcard, is not included).

Type the following command to view the details of the CTISIP translation table:

[17:22:35] ABILIS_CPX:d ctisip numbers  

Total:4        Sip-Number:3         Static:1 

NUMx:                     USER:                  Provenience:
------------------------------------------------------------
[500]                     test4                    SIP-NUMBER
[12]                      test3                    SIP-NUMBER
[11]                      test2                    SIP-NUMBER
10                        test                         STATIC

There are two types of entries:

  • SIP-NUMBER: when SIP-NUMBER is set in the SIP users chart, the CDI parameter in the chart will be the same.

    [Tip]Tip

    The connected entries are automatically added.

  • STATIC: when a SIP-NUMBER is not specified in the SIP users chart and it's associated by hand in the chart. This system is used to add several numbers to the same user (for instance in case of static routings).

Use the following commands to manage the SIP translation table:

  • a ctisip numx:<SIP-NUMBER> username:<name> : adds a new SIP-NUMBER;

  • s ctisip numx:<SIP-NUMBER> username:<name> : modifies the username of an existing SIP-NUMBER;

  • c ctisip numx:<SIP-NUMBER> : clears a SIP-NUMBER;

  • d ctisip numx:<SIP-NUMBER> : displays the list of SIP-NUMBER or a specific one.

[Tip]Tip

To a single user can be associated more SIP-numbers.

The SIP users creation generates automatically the NumSip list in which are located all the SIP-NUMBERS associated to the users (it is very useful for the CTIR configuration).

Type the following command to view the list :

[15:28:03] ABILIS_CPX:d list:numsip

LIST:NumSip               - IN                - Ref-Numb:1     Items-Numb:4    
     Automatically_generated_CTI_SIP_Numbers_list_(ReadOnly)
     --------------------------------------------------------------------------
     10                      11                      12
     500
[Note]Note

It is a “read only” list, you cannot modify it, as it is automatically created by the system.
