Free SIP

Here are some of the cloud based SIP services you can get for free:

• SIP address
  A public SIP address for receiving calls from anyone worldwide.
• SIP IVR
  A SIP-based Voice Response (IVR) that can play messages such as  “For sales press one….” to callers. 
• SIP trunk
  A SIP trunk is a connection between the traditional phone network and your SIP based phone system. 
• SIP forwarding
  Receive SIP calls or regular phone calls – and forward them to a SIP address of choice.

Here is how you can access these services for free – and how it all works.

Incoming calls to your SIP address from anyone anywhere worldwide can be answered in many ways:

• In your browser
  You can answer calls in the free Web app.
• With any SIP phone
  Calls can connected for free to any SIP device of your preference that you register with the service. This can be both software or hardware based SIP phones.
• Forwarded to any number

If you run a business and invite your entire team to the service (which is also free) – they will all get their own personal SIP address.

A SIP trunk is like a pipeline for calls – across the Internet – between the classical telephone network and your SIP based phone system.

While it isn’t possible to get a SIP trunk that is free for making outbound calls, you can surely get one that is free for limited amounts of incoming calls.

Follow these steps.

   Configure your new number to forward calls to the SIP address or IP address of your SIP server.

Free SIP forwarding allows you to forward incoming calls to a SIP address to another SIP address.

This is how it works.

1. Get the SIP address
   Sign up for a free account and then go the Advanced call settings to find your SIP address.
2. Forward calls to another SIP address
   Go to your incoming call settings, and configure that calls should be forwarded to a SIP address. Enter the destination SIP address of your choice.

Voila! You now have a new public SIP address that forwards incoming SIP calls for free to your other SIP address.

You can additionally add real phone numbers to the mix, and have them forwarded to your SIP address as well. Earlier in this article we also described how you could get a phone number for free.
