Phone Amego can be used with SugarCRM as follows.
Dialing
You can dial any phone number that appears on your screen by selecting it, and then pressing Cmd-Shift-2 (Hot Key defined under the More tab). For easier access, I recommend PopClip from Pilotmoon.
Inbound Caller ID
When a call arrives, it is possible to have SugarCRM search for a corresponding customer record based on the caller ID received. Use the following Event URL for "Open Card":
https://ratesontrack.sugarondemand.com/index.php?searchFormTab=advanced_search&module=Leads&action=index&query=true&phone_advanced={cidNumber}
The "https://ratesontrack" portion of the URL will need to be customized for your specific instance of SugarCRM.
