How can I get the name associated with an extension/peer without having an opened channel with the Asterisk's Java API?

Question

I’m using FreePBX with Asterisk’s Java API. For the moment, I’m able to display all my SIP peers with their respective states:

public void onManagerEvent(ManagerEvent event) 
{
    // Look if the event is a IP phone (Peer entry)
    if(event instanceof PeerEntryEvent)
    {
        PeerEntryEvent ev = (PeerEntryEvent)event;
        // Get the user extension
        peer = ev.getObjectName();
        // Add to the array
        peersName.add(peer);
    }
}

I’m able to display the phone number and name of both callers when a channel is open:

private String GetExtensionPeer(String extension)
{
    for (AsteriskChannel e : channels)
        if (e.number.equals(extension) && e.bridge != null )
            for (AsteriskChannel channel : channels)
                if (z.channel.equals(e.bridge))
                   return "       with " + channel.number + " - " + channel.name;
    return "";
}

But now, I would like to display the name of my extensions without a channel connection.

In FreePBX's panel, it's look like :

Answer 1

In freepbx you can get list of extensions from asterisk db. To see info, do

asterisk -rx "database show"

To get info use manager action "command" with DBGET.

Other option - got that info from freepbx's mysql db.
