Logging functionalities activation/deactivation.

Runtime CTIIAX activation/deactivation.

Maximum number of IAX simultaneous sessions.

UDP port number on which the incoming IAX (call signalling protocol) call is accepted.

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].

Sets the TOS value for CTIIAX resource.

Incoming requests: accepted source IP address [*, 1-126.x.x.x, 127.0.0.1, 128-223.x.x.x].

Incoming requests: list of further accepted source IP addresses [#, IP/IR/RU/MR listname].

Authentication method offered to authenticating/registering users (incoming calls/registrations).

Authentication method when Abilis is authenticating/registering to a peer (outgoing calls/registrations).

Default duration of incoming registration; users must register themselves before this time interval expires.

Default duration of outgoing registration; Abilis must register before this time interval expires.

CTIP type assigned to CTIIAX driver.

Enables/disables Net-Public to Net-Public call transfer [NO: NP to NP disabled; YES: NP to NP enabled, except when both calls are outgoing, which is not allowed to avoid the “hang trunk” problem; SYS: NP to NP depends on NP-CT in CtiSys].

Routing management.

Dialling timeout.

Timeout for “empty” setup.

Retransmission frequency (time interval between a retransmission attempt of a IAX full frame and another one if acknowledgement doesn't arrive).

Retransmission time limit (maximum time for which a frame can stay unacknowledged).

Retransmission time limit for NEW and REGREQ messages (these messages are used to setup a call); a shorter timeout for these messages helps in keeping small the time lost in case of peer failure and make a more effective alternative routing.

Enables/disables trunking.

Trunk frequency: it represents how much time to wait prior to send the UDP packet. During this time other voice packets coming form the same or other channels can be inserted in the same UDP header thus sensibly reducing the transmisison overhead; of course it adds some delay, but great benefit toward the bandwidth saving.

Enables/disables individual timestamps in a meta trunk.

Channel frequency for bandwidth optimisation. It represents how many msec of voice are desired to be packed into a single UDP packet; it's a “desire” in the sense that the actual optimisation will depend on the frame length in msec of the coder in use, and the result will be an a approximation by defect.

It allows routing using subaddress called field (SD) [NO: the SD is completely ignored; YES: the user corresponding to SD is searched: if found the call is forwarded to that user, otherwise the standard search in CtiIax table is performed; USER: the user corresponding to SD is searched: if found and the user has parameter IAX-ROUTE-BY-SD:YES, the call is forwarded to that user, otherwise the standard search in CtiIax table is performed].

Allows insertion of IAX USER NAME in subaddress calling field [NO: disable insertion of USERNAME in calling subaddress; YES: enable insertion of USERNAME in calling subaddress; USER: insertion of USERNAME in calling subaddress depends on individual user configuration]. When it's enabled, either as result of value YES or because value is USER and the user corresponing to the subaddress content allows it, the call sent to CTIR will include in the subaddress calling field the IAX USER NAME of the caller.

Duration of a DTMF played from a DTMF FULL FRAME. When CTIIAX has to convert a DTMF FULL FRAME command to CTIR DTMF frame, it produces as many frames as needed to cover the period specified by this parameter. The actual interval must be rounded to the value immediately higher than configured one.

Duration of a silence played after a PLAY-DTMF. When CTIIAX has to convert a DTMF FULL FRAME command to CTIR DTMF frame, it produces as many frames as needed to cover the perios specified by PLAY-DTMF parameter. Before a new DTMF can be played, a silence period must elapse, and this is controlled by this parameter.

Duration of a DTMF from CTIR in order to allow digit recognition. When CTIIAX received DTMF frames from CTIR, and after it created the most accurate and monotonical timestamp, the DTMF length is measured and for a successful digit recognition it must be of at least the length specified here. If the configured value is not an exact multiple of the frame rate, it must be rounded to the next upper value multiple of frame rate.

Duration of a silence after a DTMF from CTIR in order to recognise a digit.

Unattended call transfer handling type [IAX: the handling respects IAX specifications: the original call is dropped; CPX: the handling is modified by Abilis: the original call is kept up in case that transferred one fails(user busy, not reacheable, etc...)].

Enables/disables Call Path Optimization between two IAX users. It's used when IAX-CPO:SYS in user service, otherwise the value of IAX-CPO is used.

Earlier state of both call legs in which the Call Path Optimization can be ordered [ACCEPT: CPO on ACCEPT receiving; RINGING: CPO on RINGING receiving; ANSWER: CPO on ANSWER receiving].

Enables/disables call drop on Call Path Optimization (CPO) failure. If enabled, the call will drop if CPO will fail. It's used when IAX-CPO-DROP:SYS in user service, otherwise the value of IAX-CPO-DROP is used.

Enables/disables network statistics and checks connection every the specified value of seconds.
