Providers

There are two main types of providers for your VoIP account: Incoming and Outgoing.

  • The incoming calling is usually referred to as a DID - Direct Inward Dialing - a phone number that can be called from a regular phone on the PSTN.
  • The outgoing calling is usually referred to as a VSP - VoIP Service Provider.
  • Additionally, if you require e911, you will need to pay a monthly fee (and properly route it in your dial plan.)

Many users on SipSorcery have multiple DID providers, and multiple VSPs - a package deal may not give you the best price.

For information on how to configure your chosen provider, search for it or look at this list: Category:Config


SIP Provider Manager Configuration Information

It is possible to have incoming calls fowarded to your SIP address (your_username@sipsorcery.com) without setting up the provider information in SipSorcery (unlike outgoing, where you always need an entry). If you do this, you may want to set up a sub-user, so you can properly track which line incoming calls came in to.

The following was snatched from the SS provider help page Here's how to configure an entry in the provider's tab in your account:

The SIP Provider Manager is used to create, update and delete SIP Providers and any bindings (registrations) for them. It is also used to view SIP Provider current bindings. There are a number of properties that apply when creating or updating a SIP Provider and these are explained below:

  • Id: A GUID used by the system to uniquely store each SIP Provider.
  • Owner: The name of the username that created the SIP Provider.
  • Provider Name: The descriptive name used to identify the SIP Provider and that is used by the dialplan when placing calls with this SIP Provider.
  • Username: The username for the SIP Provider, it will be used when responding to authentication challenges for calls and registrations.
  • Password: The password for the SIP Provider, it will be used when responding to authentication challenges for calls and registrations.
  • Server: The hostname or IP address for the SIP Provider. Call and register requests will be sent to this server.
  • Register: If checked then a SIP Provider binding entry will be created and an attempt will be made to register with the SIP Provider. The status of the binding attempt will be shown in the SIP Provider Registrations table.
  • Register Contact: If the Register box is checked a SIP URI must be specified for the Register Contact. The SIP URI will be sent to the SIP Provider and informs it where incoming calls should be forwarded to. If it is desired that incoming calls for the Provider should be forwarded to the SIP Sorcery server then the Register Contact should be set as: username@sipsorcery.com where username is the SIP Account username that will receive the call.


Advanced Settings are additional settings that are not normally required but that can be used to refine the SIP Provider interaction.

  • Outbound Proxy: If set overrides the SIP Provider Server setting for call requests.
  • Auth Username: If set overrides the SIP Provider Username setting when responding to authentication challenges.
  • From Header: If set overrides the default header that is set for new calls to the SIP Provider. The default From Header for a SIP Provider is: username@server. Changing this setting has ramifications for authentication as most SIP Providers use the username portion of the From Header to identify users. An example that allows modification of display name portion of the From Header and that leaves the username and server intact is: "Your Name" <sip:username@server>.
  • Register Expiry: The number of seconds to request for the binding expiry when registering with the SIP Provider. Can be between 60 and 3600.
  • Register Realm: If set overrides the SIP Provider Server setting when responding to authentication challenges.
  • Register Server: If set overrides the SIP Provider Server setting for registration requests.
  • Custom Headers: An optional list of SIP headers that will be added to register and call requests made with the SIP Provider. Values must be entered as valid SIP headers, an example is: P-src-ip: 127.0.0.1 or User-Agent: my user agent.
