DTMF Transfer — mode of DTMF signal transmission:

• • Inband — inband transmission;
  • RFC2833 — according to RFC2833 recommendation as a dedicated payload in RTP voice packets;
  • SIP   info — transfer messages via SIP in INFO requests.
• RFC2833 Payload Type — payload type for packet transmission via RFC2833 (permitted values: from 96 to 127);
• Use the Same PT Both for Transmission and Reception — option is used in outgoing calls for payload type negotiation of events sent via RFC2833 (DTMF signals). When selected, event transmission and reception via RFC2833 is performed using the payload from 200Ok message sent by the opposite side. When unselected, event transmission is performed via RFC2833 using the payload from 200Ok being received, and reception—using the payload type from its own configuration (specified in the outgoing Invite);
• Silencedetector — when selected, enable voice activity detector;
• Echocanceller — when selected, use echo cancellation;
• Dispersion Time, ms — parameter that cancels an echo caused by the voice signal dispersion. Parameter values may be specified in the interval from 2ms to 128ms;
• RTCP — when selected, use RTCP for voice link monitoring:
  • Sending Interval — RTCP packet transmission period, in seconds;
  • Receiving Period — RTCP message reception period measured in transmission period units; if there is not a single RTCP packet received until the reception period expires, VP-12(P) will terminate the connection;
  • RTCP - XR — when selected, RTCP Extended Reports will be sent according to RFC 3611.
• Allow Call Pickup — when the flag is set, pressing the BLF key will initiate the interception of the incoming call to the subscriber on which the BLF key is configured;
• Call Pickup Mode — the way the call is intercepted:
  • Replaces — call pickup using the Replaces header;
  • Feature Code — call pickup using the prefix added to the number of the subscriber on which the BLF key is configured.
• Call Pickup Code — prefix which will be added to the number of the subscriber to which the BLF key is configured;
• Sign '#' terminates the number — adding the '#' symbol when intercepting a call after the number of the subscriber to which the BLF key is configured.

RTP

• Min RTP Port — lower limit of the RTP ports range used for voice traffic transmittion;
• Max RTP Port  — upper limit of the RTP ports range used for voice traffic transmittion.

SRTP

• Enable — when selected,RTP flow encryption is used. Thus, the RTP/SAVP profile will be specified in SDP of outgoing INVITE requests. Also, the SDP of incoming requests will be scanned for the RTP/SAVP profile. If the RTP/SAVP profile is not found, the call will be rejected;
• Crypto Suite 1-2 — allows to choose encryption and hashing algorithms to be used. A suite with the highest priority should be specified in “Crypto Suite 1” field. You have to specify at least one crypto suit:
  • AES_80 — according to AES_CM_128_HMAC_SHA1_80;
  • AES_32 — according to AES_CM_128_HMAC_SHA1_32.

Jitter Buffer

Jitter is a deviation of time periods dedicated to packet delivery. Packet delivery delay and jitter are measured in milliseconds. Jitter value is higher for real time data transfers (e.g. voice or video data).

...

• Min Delay, ms — minimum expected IP package network propagation delay;
• Max Delay, ms — maximum expected IP package network propagation delay;
• Deletion Threshold (DT) — maximum time for voice package removal from the buffer. The parameter value should be greater or equal to maximum delay;
• Jitter Factor — parameter used for jitter buffer size optimization. The recommended value is 0.

Input Gain Control

• Speakerphone — specifies the value by which a signal from the speakerphone will be amplified (valid values -9, … 9 dB, at a pitch of 1.5 dB);
• Headset — specifies the value by which a signal from the headset will be amplified(valid values -9, … 9 dB, at a pitch of 1.5 dB);
• Handset — specifies the value by which a signal from the handset will be amplified (valid values -9, … 9 dB, at a pitch of 1.5 dB).

Dialplan

To define a dialplan, use regular expressions in the 'Dial plan configuration' field. The structure and format of regular expressions that enable different dialling features are listed below.

...

• хх — arbitrary value of S and L timer. Timers inside rules could be dropped; in this case, global timer values, defined before the parentheses, will be used.
• prefix — prefix part of the rule;
• @optional — optional part of the rule (might be skipped);
• (parameters) — additional options (might be skipped).

Timers

• Interdigit Long Timer (« L » character in a dialplan record) — entry timeout for the next digit, if there are no templates that correspond to the dialled combination.
• Interdigit Short Timer (« S » character in a dialplan record) — entry timeout for the next digit, if the dialled combination fully matches at least one template and if there is at least one template that requires an extension dialling for the full match.

...

Example: (S4 8XXX. | XXX) or ([1-5] XX S0) — an entry requests instantaneous call transmission when 3-digit number dialing; a number should begin with 1,2, … ,5.

Prefix part of the rule

Prefix part might consist of the following elements: 

Optional part of rules (could be omitted)

The optional part of a rule might be omitted. This part might consist the following elements: 

Additional parameters

Format: (param1: value1, .., valueN; .. ;paramN: value1, .., valueN)

...

Examples

Example 1: ( 8 xxx xxxxxxx ) — 11-digit number beginning with 8.
