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

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.

	Tip
	Interesting chapter: Section 87.4.15, “How to solve SIP call transfer issues?”.

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].

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]. For SIP-HOST:DYNAMIC the value can't be set, it is always dynamically learned and shown as (DYNAMIC). For SIP-TYPE:NNI the range is restricted to [1..65535].

SIP UDP local port [SYS, LOCPORT-BASE..(LOCPORT-BASE + LOCPORT-RANGE)].

For SIP-TYPE:SERVER:

For SIP-TYPE:PHONE, LOCAL-PEER, REMOTE-PEER, NNI:

(E.g. 192.168.0.1 or R-ID or Ip-23).

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 "*"..

Phone number(s) are used for routing purposes (ctir -> sip user) and in accordance with SIP-CG-NUM for calling number processing. From 0 up to 20 characters [0..9, ^, ?, _, *] optionally preceded by TON [u, i, n, o, s, h, k] and/or NP [x, e, d, t, l, p] attributes. Any number of '^' and '?' is allowed, but only alone or at end of the number or after digits and before '*' or '-'. The '_' is allowed only alone or at number end. The '*' is allowed only alone or at number end. See also HELP ISDN ATTRIBUTES and HELP ISDN VALUES.

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)

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]. Any number of '^' and '?' is allowed, but only alone or at end of the number or after digits and before '*' or '-'. The '_' is allowed only alone or at number end. The '*' is allowed only alone or at number end. For SIP-TYPE:NNI the range is restricted to [*]. See also HELP ISDN ATTRIBUTES and HELP ISDN VALUES.

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].

Selects how to fill Display Name in From, P-Asserted-Identity, Remote-Party-ID fields [SYS: Use the value specified in CTISIP resource; NO: Do not add display name; CG: the value present in the CG field (calling number) provided by CTIR; SG: the value present in the SG field (subaddress calling) provided by CTIR; SG-CG: the value present in the SG field or CG field if SG field is missing; ADDRBOOK: field with the name of calling number from address book; ADDRBOOK-SG: field with calling number if the name of calling number is missing in address book].

	Note
	When SIP-TYPE:SERVER the CG is replaced by SIP-REM-USER value.

	Tip
	Interesting chapters: Chapter 69, Address Book; Section 87.4.6, “How can I activate to view the caller's name on the display of SIP phones?”.

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

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. For SIP-TYPE:NNI the range is restricted to [ENABLE].

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.

	Tip
	Interesting chapter: Section 61.4.4.2, “Abilis CTI Routing of “Site 1 ” using subaddress called field”.

Allows insertion of SIP USER NAME in subaddress calling field [NO, YES].

Enables/disables Call Path Optimization (CPO) [SYS: uses the value in CPO parameter in CTISIP resource; NO: doesn't allow CPO; YES: allows CPO].

Call Path Optimization signalling [SYS, NO, TRANSFER, ALWAYS].

Enable/disable Runtime Codec Change (RCC) [SYS, NO, YES]. This feature permits the change of the coder once the call is already established. The purpose of this feature, which is perfectly SIP compliant, is to avoid transcoding all the times that it is possible by choosing a coder which is supported by both sides although not currently in use. This feature is very effective when call transfers takes place. A user may have two calls with two different parties that use two different codec, e.g. G.711 and G.729, when a call transfer is ordered the two parties will be directly connected but since one party was using G.711 and the other G.729 we were forced to make a transcoding even if both supports G.729. With the RCC feature the party running G.711 will be changed on the fly to G.729. The run time codec change allows to save voice quality and sw and hw resource in case of transcoding. Disable the RCC only if the SIP devices have troubles in handling the codec change.

Determines if click-to-call and transfer call must be sent with autoanswer request [NO, YES, TRANSFER]:

For SIP-TYPE:NNI the range is restricted to [NO].

Enable/disable SIP supplementary services [NO, YES].

NAT Traversal method when remote user is behind NAT [NO: send audio to the UDP port specified in the SIP protocol (SDP); STRICT: Signalling and RTP must come from the same IP address, may be different from the payload of SIP signalling and SDP. It must be equal to the IP of the registration. Requires symmetric RTP (Cisco symmetric RTP), one in which the first audio part from the client behind NAT and then the server responds using the same reversed ports. In the case of transfers with optimized RTP, it uses private IP and private ports contained in SIP and SDP signalling; LOOSE: SIP signalling must indicate the IP equal to the real ones from which the packet, while the RTP (Cisco symmetric RTP) is symmetrical and the IP may be different from that used for the signalling. In the case of transfers with optimized RTP, it uses private IP and private ports contained in SIP and SDP signalling, as STRICT;].

NAT traversal method [NO In the signalling specify the real IP address of the Abilis; EXTERNAL-IP: In the signalling specify the IP address in SIP-EXTERNAL-IP parameter]. For SIP-TYPE:NNI the range is restricted to [NO].

Enable/disable Keep-alive feature [ENABLED, DISABLED]. It's very important to have the SIP-KEEPALIVE enabled to avoid pending calls.

DTMF mode sent to the remote UA [SYS: uses DTMF-MODE value in CTISIP resource; INBAND: the outband DTMF received from CTIR is not dropped, only the audio stream is passed; INFO: the outband DTMF received from CTIR is sent using INFO message; RFC2833: the outband DTMF received from CTIR is sent using RFC2833 payload].

Enable/Disable the reproduction of the audio message present in DISCONNECT with in-band-info received from CTIR [SYS, NO, YES]. If set ot YES the duration of the SIP session in active state is increased until CTIR times-out (typically up to 30 sec), or the SIP agent closes the call.
