JNSoftware has updated Dialectic (http://www.jonn8.com/dialectic/), a telephony tool for the Mac, to version 1.7. Among the new features are 64-bit compatibility, integration with Exchange, CardDAV, & LDAP accounts, and new or improved support for many devices and services including Aastra IP phones, MagicJack, and more.

Dialetic provides system-wide dialing of phone numbers using Bluetooth mobile phones, landlines, many VoIP services and more. It integrates with contact management applications such as Marketcircle Daylite, Microsoft Entourage, Now Contact, Palm Desktop, FileMaker Pro and other databases, as well as Apple’s iCal and Address Book.

In addition to dialing, the software provides a global Address Book menu for accessing your contact data including email, instant messaging, postal addresses, URLs, notes, and phone numbers. You can create new email messages, look up addresses on a map, copy data to the clipboard or insert it into your current document.

Dialetic is Universal Binary so runs natively on both PowerPC and Intel Macs. It works with Mac OS X 10.4.9 and higher. It costs US$25.
