Device settings

Screenshot

Each device can have many settings. The screenshot shows settings for an SIP device. These settings are similar to those for other device types as well.

There are several groups of settings: General, Authentication, CallerID, Network Related, Groups, Voicemail, Codecs, Allowed Addresses, Advanced, Tell Options, Debug and Recordings.

General

• Registration Status - available only for SIP devices. If device is assigned to server A but registers to server B - status will not be shown (devices must register to the server they are assigned to). If no status is displayed - device has not tried to register or noone called to that device.
• Accountcode – the unique ID of the device in the system.
• Description – for informational purposes.
• PIN – device PIN for authentication/authorization.
• Device group – to which group the device belongs (not used most of the time).
• Type – what type of device it is.
• Extension – a short number by which this device can be reached; must be unique in the system.
• DTMF Mode – in which protocol phone button presses are sent over network. The available options are: inband, info, RFC2833, and auto. Choose which one your provider uses (RFC2833 is used most often).
• Works not logged – does the user need to log into MOR GUI to be able to dial out? (This feature is mainly used for Call Center environments; keep the default in most cases).
• Location – the default is Global. Choose the appropriate location based on Localization needs.
• Timeout – how long to try to reach the device for, and when to hang up if the device does not answer.
• Trunk – No/Yes/Yes with ANI – Is this device Trunk with/without ANI?
• Call Limit – how many simultaneous calls can a user make?
• Ringing Timeout - allows to limit the ringing duration in seconds. Leave 0 for unlimited This functionality is available starting from MOR 11
  
  

Authentication

For ZAP devices:

• Channel – which channel (or channel group) to use on PRI/BRI/PSTN card. Channels and groups should be configured in zapata.conf.

For all other device types:

• Username – username you enter in your device.
• Password – password you enter in your device.
• Authenticate by IP – should the device be authenticated by IP (rather than by username/password)?

CallerID

A CallerID consists of two parts: Name and Number. The "Number" part is transferred by default by all technologies (GSM, PSTN, SIP etc), but the "Name" part is transferred only by some. The number you see on your mobile phone when someone is calling you is the "Number" part.

• Name – the "Name" part of the CallerID.
• Number – the "Number" part of the CallerID.

NOTE: if you leave these fields empty, the user can set the CallerID by himself. Usually it is not advisable to allow the user do it on his own.

• Number from DID - use the DID as the CallerID (only available when the device has DIDs).
• CID control by DIDs – only available when the device has DIDs.

This setting lets you control what a CID user can enter in his devices. CID numbers should be from the set of the device's DIDs. They are mainly used when the user's PBX is connected over Trunk and many DIDs are routed to this Trunk. Calls coming out from this PBX must have a CallerID Number from the set of DIDs assigned to this Trunk (PBX). If "CID from DIDs" is checked, the system checks whether the device's CID number is from DIDs assigned to this device. If no DIDs are assigned, this value is ignored. In order for this setting to be active, CID Name/Number fields must be empty to allow the user to enter any CID number he wants. If "CID from DIDs" is checked and user enters any CID (not from his DIDs), the system will change his CID by his first available DID (selected from database by lowest ID).

Network Related

• Host – the device IP or hostname; the value can be "dynamic", which means that device should register (it should be like this most of the time).
• IP Address – should be the device's IP, or disabled if the device is "dynamic".
• Port – the port used to connect to the device (the defaults are 5060 for SIP, and 4569 for IAX2). If host = dynamic, this field is updated by Asterisk when the device registers. It is the port from where the call is coming (from the device).
• Last time registered – when device was last time registered to the Asterisk server.
• Media control – can reinvite/transfer. Do you want your server to stay in media path between your clients and your provider?
• NAT – the available options are: yes, no, never, route. For a detailed explanation of these settings, refer to here.
• Qualify – how often to "ask" the device about availability. More details here for SIP devices and here for IAX2 devices.

Groups

• Call Group – to which Call Group this device belongs.
• Pickup Group – which Call Groups this device can pick up.

Voicemail

• Email – where to send received Voicemail.
• Password – the digital password the user enters when he calls the Voicemail number to hear his messages.

Codecs

Choose the codecs your provider uses.

NOTES:

• When no fields are checked, all codecs are available – for example, settings in sip.conf or iax.conf are effective.
• If the Provider and the Device do not have similar codecs, no call can be established.

Allowed Addresses

IP, MASK – permits traffic from this IP only. You can find a detailed explanation here.

If you do not clearly understand what these settings are used for, leave them with default values.

Advanced

• Fromuser/Fromdomain – used when calling TO this peer FROM Asterisk. If you're using _register=>_ with another SIP proxy, this setting can come in handy since some SIP networks only allow users in the right domain with the correct user name.
• Trustrpid – defines whether or not Remote-Party-ID is trusted. It's defined in http://tools.ietf.org/id/draft-ietf-sip-privacy-04.txt.
• Sendrpid – defines whether a Remote-Party-ID SIP header should be sent. The default setting is "no". This field is often used by wholesale VoIP providers to provide calling party identity regardless of the privacy settings (the From SIP header).
• Insecure
  • port: ignore the port number where request came from.
  • invite: don't require authentication of incoming INVITEs.
  • port, invite: don't require initial INVITE to authenticate and ignore the port where the request came from.
• T.38 support - Asterisk does not have good T.38 support, so use this option just for testing.
• SIP 302 Reinvite support - SIP Reinvite support for the device. Disabled by default.
• Progressinband:
  • yes - when "RING" event is requested, always send 180 Ringing (if it hasn't been sent yet) followed by 183 Session Progress and in-band audio.
  • no - send 180 Ringing if 183 has not yet been sent, establishing an audio path. If the audio path is established already (with 183), then send in-band ringing (this is the way Asterisk historically behaved because of buggy phones like Polycom's).
  • never - whenever ringing occurs, send "180 ringing" as long as "200 OK" has not yet been sent. This is the default behavior of Asterisk.
• Video support – does your provider support Video over IP? More info here.
• Allow duplicate calls - the default setting is "no".
• Language - sets IVR language
• Use ANI (if available) for CallerID: - When the call comes the information about who is calling is found in CallerID field. This field is used to determine who is calling. When the call comes through PRI/SS7 channels - then additional information is available who is calling in ANI field (in call's data channel) so sometimes CallerID might be empty or anonymous, but the caller can be found in ANI field. This option allows to use ANI field as CallerID to determine and recognize who is calling.
• Incoming Call CallerID Presentation - sets CallerID Presentation. Please note that this setting applies only for incoming calls. More information can be found here and here
• Change Failed Code To - if call fails change Hangup Cause Code to this value.
• Forward DID - it allows to forward call to DID which is assigned to Authorization by PIN or Calling Cards dial plan. After user enters PIN of any device or card, call gets connected with destination.

Tell Options

• Tell balance – should MOR tell the user his balance every time he tries to dial? The default setting is "no".
• Tell time - should MOR tell the user his remaining time every time he tries to dial? The default setting is "no".
  • Time is told in MINUTES and SECONDS. Currently it is not possible to tell ONLY in minutes.
• Tell remaining time when left – when some time is left, MOR will tell the remaining time to talk (in seconds).
• Repeat remaining time when left – repeats the remaining time when some time is left (in seconds).

Debug

SIP debug info - can be enabled per SIP device basis. It is useful in debugging. When this feature is enabled, the info is saved to the calls table.

Recordings

This section is available when Recordings Addon is installed in the system.
