Is there a dial from Addres Book and tel:/sip: protocol handler script/application available for 10.7? We are currently using Mac OS X 10.6 and snomURLHandler to convert tel: uri's to a http GET request. This computer telephony integration let us click on a telephone number in Address Book.app and let our desktop phone dial the number.

As snomURLHandler version 1.0 by Alastair J. Houghton (2004) is compiled to PowerPC code, and the Rosetta component to run PowerPC code is no longer available in 10.7 (Lion), this situation is blocking upgrade to 10.7 (Lion).

What alternatives are available for snomURLHandler, preferrably a script or application that can be used as a general tel: and sip: protocol handler (to call links starting with tel: and sip: from a web browser) and also be used from Address Book.app?

Note: We are aware of Telify add-on. That is not what is asked for, as Telify only works in one browser (Firefox) and cannot be used from Address Book.app
The source code of snomURLHandler is available at http://alastairs-place.net/hg/snomURLHandler/file/eb798e1a6dc8

Download that source code and compile this to an application using Xcode.
