Try Click-to-Call. Right before it actually dials, the browser will give you the URL for your bookmarking pleasure. There might be a time-to-live on the hashes. I haven't experimented with it long enough. javascript:ctc_a.prototype.ba=function(a,b,c,d,e){var g="/maps/call",h="from="+a+"&to="+b+(c?"&redirect_url="+escape(c):(d?"&ticket="+d:""))+"&hmac="+e+(this.p?"&save_phone_cookie=1":"");prompt("Bookmarklet URL","http://www.google.com"+g+"?"+h);this.x(g,h)};void(0); Also, don't forget this URL: http://www.google.com/maps/call/cancel?call_id= Use the call_id that is returned from the xml that is returned from the 'call' URL.

javascript:ctc_a.prototype.ba=function(a,b,c,d,e){var g=”/maps/call”,h=”from=”+a+”&to=”+b+(c?”&redirect_url=”+escape(c):(d?”&ticket=”+d:”"))+”&hmac=”+e+(this.p?”&save_phone_cookie=1″:”");prompt(”Bookmarklet URL”,”http://www.google.com”+g+”?”+h);this.x(g,h)};void(0);

Also, don’t forget this URL:

http://www.google.com/maps/call/cancel?call_id=

Use the call_id that is returned from the xml that is returned from the ‘call’ URL.

They are passed in as part of the business listing search results and are hardcoded into the vpage iframe together with the phone number. They are generated server-side for each business phone number and must correspond with the number when passed to the 'call' url.
