SIP Broker

Here's how it works:

1) Suppose you dial 1-415-817-1717 or 81-3-3580-3311 or 011-65-6736-2000 or 00-61-13-13-13 or 0011-44-870-444-1500. Since none of these numbers have ENUM entries, the call will be handled the same way it is with your existing setup. For example, if your existing provider plays a balance notification message and then connects the call, that's what you will continue to hear. (The way this works is that if an ENUM entry is NOT found for the number you dialed, SIPbroker.com redirects the call back to sip:theExactNumberYouDialed@yourSIPproxy.com, so that your SIP adapter will place the call in exactly the same way as if SIPbroker.com had never been involved.)

2) Suppose you dial 1-604-484-5289 or 1-800-555-8355 or 1-888-842-7245 or 44-800-699-996 or 00-49-800-101-2964. Since all of these numbers have ENUM entries, SIPbroker.com redirects the call to the appropriate SIP URI. You may notice that you do NOT hear your provider's balance notification message (because the call is free), that the call is connected very quickly, and that voice quality is better than ususal.

3) SIPbroker will continue to map numeric prefixes to open SIP proxy domains, so that your hardware adapter can call numbers that aren't peering partners of your current provider, although a '*' is now required before the old prefix numbers. For example, the old 393-613 is now *393-613.

Calling across VoIP providers (Peering)

We all know that calling SIP URIs on the same provider is easy, however, consider the case where your SIP URI is 111@xxx.com and the person you want to call is 222@yyy.com. You cannot do this easily using the numeric keypad on your phone, because SIP is expecting the yyy.com to be explicitly defined.

The current solution is to manage that using name and address books inside your phone.

SIP Broker solves this problem by creating a unique 4 digit prefix (SIP-Code) that identifies the yyy.com provider.

For example,

SIP Broker may allocate *123 as the SIP-Code for the yyy.com provider, so you would call *123222. All other numbers at yyy.com can be reached by dialing the same *123 SIP-Code.

This scenario only requires you (the caller) to be registered with SIP Broker.

You would like an easy number to remember

Some providers are in the habit of allocating 12 digit numbers that are impossible to remember. As an additional service, you can allocate a "SIP Broker Alias" that is keyed on country and a unique number that you choose (assuming someone else hasn't already chosen it).

So, if you choose Australia as your country (IDD code 61) and a phone number of 123, then your SIP Broker Alias is 61123.

Your phone alias can be as short or long as you like.

To call someone's SIP Broker Alias, both parties need to be registered with SIP Broker, and need to prefix calls with the SIP Broker Alias SIP-Code (*011). In the example above, the number that would be dialled is *01161123.

Note that registering with SIP Broker is free and has no obligation. We are not providers; we just simple provide a brokering/re-routing of calls between your existing providers.
