For more information on [sip-code][number], see article Get a SIP Broker alias.

A SIP Broker “alias”, is a SIP Broker “number” that starts with *011 (as dialed from SIP Broker) that is translated (by SIP Broker) into the full SIP URI (internet phone address) to reach your VoIP adapter. Essentially it is a “number” that is dialable (using JUST the normal keys on a phone) that can reach you by anyone using SIP Broker.

You have to already have a valid internet VoIP address that can ring your adapter, but the SIP Broker “alias” can make it easier for SIP Broker users (including users of the free SIP Broker PSTN inbound numbers) to easily dial your adapter.

Essentially it just gives you an easy “alias” for your existing VoIP adapter address.

Enjoy free, unlimited SIP calling and SIP addresses.
