I'm new to Hamnet, and I need some help getting started with VoIP over hamnet.  I would like to make direct phone-to-phone calls without using a PBX.  Since the Grandstream HT701 can connect using the IP address of the phone to call, they look like possible candidates.

Does anyone have any experience with Grandstream products such as the HT701?

I believe port forwarding needs to be used to connect to an external device like this, but it's not clear to me if the device should be connected to the LAN or WAN port on the router.

Thanks,

I've demoed voip a few times.

Connect the phones to the LAN port of the nodes. Assumption is default Lan-direct mode (not lan-nat, but this also can work) and that a voip phone will use dhcp by default to obtain on IP address. Go into setup for "reserved addresses". reserve the IP address to the phone and record it's IP address. This is an IP address known on the mesh by all nodes and hosts to correctly route. Setup memory IP dial on each phone and call away. Optionally, on the same setup screen, add the "advertised service" that you have a Voip phone. Other mesh'ers will know what IP address they can call you with. Others may be able to comment on this specific voip phone.

Also Don, KE6BXT, posted a video on this website showing the set up of other voip devices to take a look at as well.

Great pic!
