SIP Broker is a non-commercial Voice over IP network company owned by teamburns.com.[1]
SIP Broker is a free service that improves a SIP telephone service by a number of innovative features.
ENUM with automatic PSTN fallback
People who have a PSTN phone (or a DID) can map that phone number to a SIP URI (for free at e164.org) – that mapping is called ENUM. Whenever someone calls that PSTN phone number from a SIP client or proxy that checks ENUM, the call goes to the mapped SIP URI (rather than via PSTN) and is free.
With SIP Broker, if an ENUM entry is not found, then the call is sent back to the SIP adapter, which then places the call in exactly the same way as if SIP Broker had never been involved. So if a SIP adapter is registered with a prepaid SIP-to-PSTN gateway (like SIPphone or OZtell), then the call will continue regardless if SIP Broker was able to find an ENUM entry.
SIPdomain-to-numericPrefix mapping
Dialing a direct URI can be difficult since phone keypads do not usually include characters other than numbers. SIP Broker maps – for instance – 'Ekiga.net' to '*673', so you would just dial '*673' followed by the number in the SIP address. This works for providers peering with SIP Broker to dial out.
There are over 1000 of these mappings, allowing someone to reach any open SIP proxy (that is, any SIP proxy that doesn't block incoming SIP calls from non-business-partner external domains).
In addition, SIP Broker allows to register shortcuts for SIP addresses that can then be dialed as '*011' followed by the shortcut.
