In this article, we’ll guide you through the process of ordering a DID number on IllyVoIP, setting it up to receive calls on your SIP account, forwarding calls to an international phone number, or routing them to an external SIP server using IP authentication.

What is DID (Direct Inward Dialing)?

DID, or Direct Inward Dialing, is a telephony service that allows businesses and individuals to have virtual phone numbers that route calls directly to specific destinations—such as a SIP account, an external phone number, or an IP-based system.

Instead of requiring a separate physical phone line for each number, a DID number works over VoIP or PBX systems, making it a cost-effective and flexible solution for managing inbound calls.

With DID numbers, businesses can:
Assign unique phone numbers to employees, departments, or services without needing multiple landlines.
Route calls efficiently to a SIP account, mobile, landline, or an external SIP server.
Expand their global presence by having local numbers in different countries, allowing customers to call at local rates.

In short, DID numbers simplify communication, reduce costs, and improve call management—making them an essential tool for VoIP users and businesses worldwide.

To order and use a DID number on IllyVoIP, you first need to have an IllyVoIP account .

DID Number Activation and Call Routing Options

Step 1: Configuring DID number

Once your number is active, you can start using it. However, before receiving calls, you need to configure the DID number and choose where to route inbound calls.

Step 2: Choosing Your Call Routing Option

IllyVoIP offers three options for routing inbound calls from your DID number:

1. Route to SIP Extension

   This option forwards all inbound calls directly to your SIP account, allowing you to answer calls using a softphone or IP phone.

   

2. Route to an International Number

   This option forwards calls to a international phone number. For example, if you enter your local SIM card number, any call to your US DID number will be forwarded to your local mobile or landline.

   

3. Route to an External SIP Server

   You can route calls to a third-party SIP server, such as 3CX, MagnusBilling, or other softswitches. This is useful if you want to manage calls through an external PBX system.
