Trunks

Trunks are a transmission line between two systems. This transmission is done using a wide range of PSTN and VOIP technologies. This screen lists all system Trunks with the following details:

  • Name

    This field tell us name of the trunk.
    (ex. It can be TrunkName or IP address 192.168.1.6)
    (Display)

  • Provider

    Provider template name.
    (ex. SIP TRUNK)

  • Channels

    Maximum number of inbound/outbound channels available for the trunk.
    e.g. 10/10

  • Trunk Type

    Type of a trunk
    (ex. PSTN, VOIP etc.)

  • Protocol

    Protocol used by the trunk
    (ex. SIP, IAX etc.)

Add/Edit Trunk

When adding a new trunk, the first step requires ‘Provider’ and ‘Device’ selection.

TIP:

Although a new trunk can be created without it, it is preferred that the ‘Provider’ template be created first under ‘Settings: Providers’.

For basic Provider and Trunk HowTo check our HOWTO Create a Trunk

  • Provider

    Select a service provider template.
    (ex. BT)
    (Select box)

  • Device

    If the providers service requires a device in order to provide the service, this field will become visible.
    (ex. None, T100)
    (Select box)

VoIP (SIP/IAX)

The second step of the trunk installation and trunk edit command, opens the following options:

  • Name or Number

    Some providers require this field to be equal to the DID number (e.g.55510205); but if connecting two systems, the IP address may be used as well.
    (ex. 2554433, myvoiceboxlink)
    ([a-z] [0-9])

  • Emergency trunk

    Should emergency services (Police, Ambulance etc) be dialed through this trunk.
    (ex. Dialing 911 will pass the call through this trunk)
    (Option buttons)

Advanced Options

General

These options are used frequently and required for normal trunk operation. Some of these fields are pre-configured with the default values. It is not recommended to change them.

  • User Type

    The user’s relationship to the system
    Example:

    • user – The trunk accepts incoming calls only
    • peer – The trunk makes outgoing calls only
    • friend – The trunk does both incoming and outgoing calls

    (Select box)

  • DTMF Mode (Dual Tone Multi-Frequency)
    Trunk DTMF mode. A specific frequency (consisting of two separate tones) to each key so that it can be easily identified by a microprocessor

    rfc2833

      • – default

    info

      • – SIP INFO messages

    (Select box)

  • RFC2833 Compensate (1.2)

    Compensate for pre-1.4 Asterisk DTMF transmission from another machine. You must have this turned on or DTMF reception will work improperly.
    (ex. Yes, No, N/A)
    (Option buttons)

  • Context

    (Option buttons)

  • Pass-thru mode

    Pass the digits dialed without any conversion (E164, National, Area code).

    NOTE: When active, ‘Leave National Code and ‘Local Area Code’ will be disabled.
    (ex. If this option is disabled, PBXware will convert all dialed numbers to E164 format (COUNTRY_CODE + AREA_CODE + DIALED_NUMBER) and then make a call to converted number. If this option is enabled, PBXware will directly call the DIALED_NUMBER without making any number conversions)
    (Option buttons)

  • Leave National Code

    In some countries, the national code is stripped automatically. If set to ‘Yes’, the national code will not be stripped from the dialed number.

    NOTE: Before setting this option to ‘Yes’, go to ‘Settings: Servers’ and enable this option as well.
    (ex. 035123456 will not be striped of 0)
    (Option buttons)

  • Local Area Code

    Add the local area code to the dialed number, if required by the service provider. (By default, the local area code is stripped when dialing).

    (ex. 55599999)
    ([0-9])

  • Allow ES Caller ID

    Should ES (Enhanced Services) caller id be allowed over this trunk.
    (ex. Any extension can set a custom caller id for each system trunk. With this option enabled, that caller id will be used instead of the trunk outbound caller ID).
    ([0-9])

  • Test number

    This is the number that the trunk will try to call when Trunk Monitoring is turned on. If the answer is not: ANSWER, BUSY, CANCEL, or NOANSWER, this call is considered non-functional and the monitoring system will send a notification email.
    (1009)
    ([0-9])

  • Send PAI header

    The P-Asserted-Identity contains the caller ID information for the call on the INVITE SIP packet. This is the acceptable way to specify privacy information for calls. This field enables you to send preferred PAI header using several variables:

Network Related

These options set important network related values regarding NAT.

  • Transport:

    Type of transfer protocol that will be used on PBXware.

    UDP (User Datagram Protocol) – With UDP, computer applications can send messages, in this case referred to as datagrams, to other hosts on an Internet Protocol (IP) network without prior communications to set up special transmission channels or data paths.
    TCP (Transmission Control Protocol) – provides reliable, ordered, error-checked delivery of a stream of octets between programs running on computers connected to an intranet or the public Internet.
    TLS (Transport Layer Security) – cryptographic protocol that provide communication security over the Internet.[1] They use asymmetric cryptography for authentication of key exchange, symmetric encryption for confidentiality, and message authentication codes for message integrity.

    Type: Checkbox

  • Encryption:

    This option enables or disables encryption in PBXware transport.
    Options: Yes, No, N/A.

  • Direct media

    Should you allow RTP voice traffic to bypass PBXware.

    (ex. Some devices do not support this especially if one of them is behind a NAT).
    (Options buttons)

  • Direct RTP setup:

    Here you can enable or disable the new experimental direct RTP setup. Setting this value to yes sets up the call directly with media peer-2-peer without re-invites. Will not work for video and cases where the callee sends RTP payloads and fmtp headers in the 200 OK that does not match the callers INVITE. This will also fail if directmedia is enabled when the device is actually behind NAT.
    Options: Yes, No, N/A

Custom Trunks

Custom trunks are used in rare cases when PBXwares trunk setup features are not providing enough flexibility for some provider configurations. In such cases one will create a custom trunk and then change the dialplan in the trunks-in.conf file.
For information on how to modify asterisk diaplan, please check sites like www.voip-info.org

Add Custom Trunk

When you click on Add Custom Trunk button, you will get following screen:
Edit Custom Trunks options

It is the same screen when adding or editing the current custom trunk.

  • Trunk

  • Context

    Context by which the system sees this trunk and which will be used when editing the dialplan.
    (ex. Set gl_trunk for example, and when sending calls to this trunk, you would use this to refer to the given trunk).
