Push to Talk

Am switching over to an iPhone from a Samsung dumb phone.

What the Samsung offered was PTT (push to talk) where voice recognition stepped in. Only had to say "call office"

Is this technology possible with an older iPhone (no Siri)?

If not what is the best way to make hands free calls from numbers stored in the phone?

What you just described is not PTT.

Must be a Samsung term or AT&T

Our old Moto flip phone has the same feature (w/ Verizon)

We clip to the automobile visor and simply reach up and press (the correct button) to turn on voice command.

What you're referring to is voice dialing, not PTT. Older iPhones sans Siri (3GS & 4) support voice dialing.

3G as well?

How is it accomplished?

Just got the iPhone 3G so am out of the loop.

Only 3GS and later.

PTT is a two-way communication service that works like a "walkie talkie".

A normal cell phone call is full-duplex, meaning both parties can hear each other at the same time. PTT is half-duplex, meaning communication can only travel in one direction at any given moment; only one person can be heard at a time.

To control which person can speak and be heard, PTT requires the person speaking to push a button while talking and then release it when they are done (hence the term Push To Talk.) The listener then presses their button to respond.

Most PTT systems allow group calling, meaning one person can speak to everyone in their assigned or current group at once, just by pressing a PTT key.

Some new PTT systems introduced in 2003 and later use VoIP technology to provide PTT service digitally over 3G data networks.

Okay? That's still not what he wants to accomplish, hence PTT was not what he thought it meant.
