Description

In the old PSTN world, Providers were called Trunks. Providers are your route out of your VoIP network to the outside world.

Providers can be one of several types: ZAP, SIP, IAX2, and H323. The type determines which technology is used to connect to the Provider.

At the very start, you need to create a Provider through which you will dial out to PSTN or other VoIP networks.

Every Provider will charge you for calling a destination through his service (although the rate might be zero). The rate to every destination is different. Because of this, we need to have a Tariff (or Price List) for each Provider. This Tariff will tell our billing what price we will pay to a destination when using this Provider's services. In other words, this will be our Selfcost.

Providers' configurations can be found in SETTINGS –> Billing –> Providers.

Here, enter the name for a new provider, select its type and tariff, and click Create.

NOTE:

  • You can't create new a Provider if there are no Tariffs available for Providers.
  • A Provider is also able to send calls, not just receive them. More info here.

Settings

General

  • Name – a name for the provider, for informational purposes.
  • Technology – out of SIP/IAX2/ZAP/H323, choose which technology your provider uses - that is, the way you connect to the provider.
  • Tariff – the list of rates the provider charges you.
  • DTMF Mode – the available options are inband, info, RFC2833, and auto. Choose the one used by your provider.
  • Location – which Localization rules are set to apply to INCOMING calls COMING FROM this provider.
  • Automatic Number Identification - used in a special case explained here: Provider with ANI
  • Timeout – this setting lets you set for how long this provider should be dialed before giving up. The default value is 60 seconds, and the minimum value is 30 seconds.
  • Device ID – informational data. No longer used starting from MOR 0.8.
  • Call limit – explained here: Simultaneous call limitation.
  • Hidden? - hide/unhide provider

Authentication

For ZAP providers

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

For SIP/IAX2 providers

  • Login – username if your provider asks for it.
  • Password – password used for authentication by your provider.
  • Authenticate by IP – just check the checkbox (Login/Password can be left empty).
    • Make sure you put the correct Hostname/IP address!
  • Register – should we register the provider? (option is not visible when Dynamic is selected in Network related section)
  • Register extension – if the provider asks to use an extension for registration (usually they don't), enter it here.

Provider CallerID

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

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

NOTE: if you leave these fields empty, calls coming from this provider will have CallerID set by the Provider. It should almost always be this way.


Network related

  • Hostname – hostname of the provider.
  • Server IP – the provider's IP. The value can be "dynamic", which means that provider can change its IP. To discover this value, do ping to the provider's hostname.
  • Port – port used to connect to the provider (default: 5060 for SIP, 4569 for IAX2, 1720 for H323).
  • Media control – canreinvite/transfer. Do you want your server to stay in the media path between your clients and your provider? Disable if you have a lot of 1-second answered calls.
  • NAT – the available options are: yes, no, never, and route. For a detailed explanation of these settings, refer to here.
  • Qualify – how often to "ask" the provider about availability. More details here for SIP providers and here for IAX2 providers.
  • Fast Start – an option specific to H323; it is either on or off.
  • h245 Tunneling – an option specific to H323; it is either on or off.

Codecs

Choose the codecs your provider uses.

NOTE: When no fields are checked, all codecs are available. (Asterisk icon.png For example, settings in sip.conf or iax.conf are effective).

Advanced

  • Grace time - if call duration is less than Grace Time, it will not be accounted.
  • 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".
  • Interpret NO ANSWER as FAILED -
  • Interpret BUSY as FAILED
  • Fake Ring - should system generate Fake Ring or not? Use only if your Device/Provider has bad protocol implementation and does not send RING signal properly.
  • Common Use - Provider can be used by Resellers which are able to create their own Providers. Reseller will be billed using this Provider.



Allowed addresses

IP, MASK – permit traffic from these IPs only. You can find a detailed explanation here.
