How do I splice 2 cell phone voice cables together Answered

I have a Palm Treo 700p and a PhoneLabs Dock n Talk that I'd like to connect. Currently, the only way to connect them is via Bluetooth, which stinks, as there is a long lag between placing/answering a call and making the actual connection. Some phones connect via cable, which has no lag (these cables carry voice, similar to a handsfree cable). I've got the cable that plugs into the Dock n Talk box and I've got two different cable choices for my Palm (2.5mm headphone jack for voice/handsfree, and a Palm/USB data cable: http://www.amazon.com/SYNC-CABLE-PALM-TREO-700wx/dp/B0030BH3EC).

Can I splice anything together to connect the Dock n Talk to my Palm via cable?
