JNSoftware has released Dialectic 1.7, a significant update to its popular telephony software for Mac OS X. Dialectic is a TidBITS favorite (see "Dialectic Simplifies Dialing Any Type of Phone," 10 April 2008) that lets you manage the telephone calls you make, regardless of what type of phone you use. New features in version 1.7 include 64-bit compatibility (under Mac OS X 10.6 Snow Leopard); support for Exchange, CardDAV, and LDAP accounts; and more and better support for a wide range of devices like the MagicJack and Aastra IP phones. The software requires Mac OS X 10.4 Tiger or higher; full release notes are available. ($25 new, free update, 7.8 MB)
