This is off topic for the original thread, but I'll answer it here anyway.

Act version 6 (2004) comes with both Act Link 2.0 and Act for PalmOS when you purchase it. If you have an older version the Link is a free download and the PalmOS version is about $60 unless you get it on eBay.

If you use Act Link it will hotsync your Act data to the Palm address book. Then you tap the contact's number to dial it.

If you use Act for PalmOS things change quite a bit. This is a scaled down version of the PC software so you can enter notes, history, calls/meetings/to-do's are linked to the contacts, etc. Now your hotsync conduit will direct data into the ActPalmOS application, NOT the Palm address book or Palm calendar. <B>Do NOT use both the Link and the PalmOS version. It will screw everything up.</B> If you choose THIS option, there is a telephony hotfix Act has posted on their site which may fix the autodialer issue. The thing is, you always need to be within the Act software to dial contacts and there's a phone icon in the lower right corner of a contact screen. It's a little clunky because you have to tap the phone icon, select the number if there's multiple ones, and then tap dial (so, there's three or four taps of the stylus). If you are in list view with the phone numbers on the right you can dial with two taps instead of three.

From my own experience I can tell you both methods will work fine, it depends on the functionality you require. A note on hotsyncing.... my Act for PalmOS usually requires 2-3 hotsyncs for it to complete with no errors. This happens when I've been using my Treo 600 all day on the road and do my nightly sync. It says there are records being edited on the PC even though there aren't. No loss of data has ever occurred as long as I've completed multiple hotsyncs. Another bug I found is that sometimes meetings are linked to the wrong contact. Not real sure the source of this one...

One more thing, whichever way you decide to go, you CAN combine conduits. In my case I use the Palm address book with Palm Desktop because there's some phone numbers I didn't want in Act. If you use your phone with mail you could probably configure a conduit for Outlook or something without interfering with the Act data. Have fun configuring this stuff though!
