The VoIP provider have looked at the router setup and VoIP adaptor setup, and think it looks fine - right port-opening/-forwarding etc., but I thought maybe there was some incompability with the setup for the phones in their market compared to the Taiwanese phones.
I will continue my dialog with the provider.
Thanks a lot!
Big Fluffy Matthew,
There’s other wifi phones out there already that are standards based instead of locked to a proprietary service like Skype. The big things about this announcement are that 1) This is one of first Skype phones that doesn’t rely on your PC and 2) The US$150 price is significantly lower than the US$170-300 for previous wifi phones. Hopefully this will bring prices down. And as you mention it’s not really a replacement for a cell phone yet, as wifi isn’t that widespread.
If you’re doing port forwarding instead of using a STUN proxy, make sure you do port forwarding for both tcp AND udp. Session setup is over tcp but the voice packets are udp. Also you may need to set the adaptor to report your external IP address to the SIP server instead of the internal address.
Finally found this one in Gunghua market.
Unfortunately, internet reviews aren’t too encouraging. Did anybody see anything comparable?
[quote=“jlick”]There’s other wifi phones out there already that are standards based instead of locked to a proprietary service like Skype.[/quote]Yes, but looking at the vonage homepage, it looked very limited, it seems designed for residents of the USA. And the problems and confusions stated in this thread are a little offputting too.
I am a few steps closer to solving the problem now.
As my router have fixed IP address, we skipped the Stun server (NAT traversal to “NO”), and used the fixed address as NAT IP for SID/SDP message.
The adaptor is now DMZ’d, and the correct ports are opened/forwarded in both router and VoIP adaptor.
I can now make and receive phonecalls, I can hear the other party very fine, but they can not hear me. Maybe the microphone on my phone is broken, or there is something about the setting for local phone’s impedane, voltage etc. I will try another phone tommorrow, and if that give the same result, I will have to fiddle around with the phone settings.

X3M, I can tell you that your phone is not broken, you have some problem with udp-packets for the sound. I suggest that you check your firewall settings one more time for the outbound packets.
It’s still possible that the microphone is broken, but it is almost certainly not an impedance setting problem. Impedance mismatch would result in the sound being too soft, too loud, or noisy or muffled. It wouldn’t drop the sound entirely. I’ll agree with stralle though, that it’s likely you still have a networking problem. Having done this before, using a STUN proxy is by far the easiest way to solve these problems, so I’m surprised your provider doesn’t use that.
BFM, The sorts of problems X3M is having are not typical of the consumer level VOIP solutions like Vonage or Packet8. They only need you to hook up the adaptor, and at most enter an activation code before using it.

I changed the phone, and have now communication both ways with approx. 1 sec. delay when calling a Taiwan.
I am sorry if my problemsolving attempts here is confusing for some that consider a VoIP solution. As jlick says, it is not supposed to be this complicated. However, those of us who are not familiar with port forwarding/opening and fixed/dynamic IP adresses, can easily get a bit lost while fiddling around, trying to set up the router and adaptor to communicate.
For those specially interested in the user manual and set-up instructions for this Grandstream HandyTone-486 adaptor, here is some links (as you will find, there is tons of options to do anything wrong…)

Anyway, it works now, and I can start trying to set up the fax… :s
Thanks to all of you for your good advise and efforts to help med out.
Big Fluffy Matthew,
Looks like there’s several wifi phones in the pipeline with prices as low as US$100: digitimes.com/news/a20051122A8045.html (subscriber only after a week)
