Google Voice

Google Voice Applications


Adobe AIR Desktop Utility for Google Voice


Run it, log in your gv account and you can make call “connections”.

Chrome Extensions:


Google Voice in your mobile browser:

All these are to used to make calls through google voice easier.

When we make calls from google voice account, usually, we need something to receive the calls. GV makes the connection. However, google voice on mobile seems to be able to make calls directly.

With a computer only (when I don’t have a phone available), my favorite way to receive calls is using sip account. It could be anything like gizmo5, fwd, voipuser, voxalot etc. Set it up on a sip client like xlite/eyebeam, connect the account to ipkall. So when you make a call through google voice, GV->ipkall#->SIP(you pick up)->Callee#.

More details please check it here:

If you are ubuntu, linphone is highly recommended. Since empathy, xlite2.0 etc all gave me problems.

Inbound Calls Directly to your LinkSys or Sipura


How to accept direct inbound calls to your LinkSys/Sipura adapter, bypassing all VoIP providers.
  • Does your registered provider not allow inbound SIP URI calls?
  • Do you want to cut down on latency/echo, by bypassing your VoIP provider on inbound VoIP calls?
  • Do you simply like the idea of allowing calls directly into your VoIP adapter?

If you said yes to any of the above, then this FAQ page may be for you. Here is a description of how to let your LinkSys/Sipura model adapter accept calls directly from a SIP URI (internet VoIP address), bypassing all VoIP providers in the process. Here’s how to do it:

  • Setup your adapter for use behind a NAT router
    • Setup STUN on your adapter (NOTE: STUN settings are on the SIP tab)
      • Handle VIA received: no
      • Handle VIA rport: no
      • Insert VIA received: no
      • Insert VIA rport: no
      • Substitute VIA Addr: yes
      • Send Resp To Src Port: yes
      • STUN Enable: yes
      • STUN Test Enable: no
      • STUN Server:
        • NOTE: You can replace the above STUN server with any STUN server you like…
      • EXT IP:
        • NOTE: Leave this setting blank, STUN will figure this out for you…
      • EXT RTP Port Min:
        • NOTE: Normally you can leave this blank, but you can set this if you have a specific need
      • NAT Keep Alive Intvl: 45
        • NOTE: Use an value SHORTER than the “timeout” value in your router.
    • set “NAT Mapping Enable: yes
  • Set “Ans Call Without Reg: yes” on your adapter settings
  • Make sure your adapter is on the default SIP port
    • i.e. “SIP Port: 5060
  • Make sure that SOMETHING is set for “User ID:”
    • NOTE: If your adapter is “registered” with a VoIP provider, this will be your real “User ID”
  • Make sure NOTHING is in “Outbound Proxy:” field on your adapter
    • NOTE: This field is not normally needed if/when you have STUN setup (as above)
  • Forward UDP port 5060 to your adapter
    • NOTE: This may be easier if you use a static LAN address for your VoIP adapter
  • Set up a “dynamic DNS” service for your LAN
    • NOTE: The free service from “” works fine for this

If all of the above is setup correctly, then anyone on the internet can directly call your LinkSys/Sipura VoIP adapter by calling “sip:userid@dyamic_dns_address”. For example, if your userid is “12345”, and your dynamic DNS entry is “”, then your SIP URI is “”.

NOTE: One useful purpose of this, is to point a free number to your Sipura. You do this by logging into your IPKall account, and filling in your “UserID” info (12345 in this example) for “SIP Phone Number:” and your dynamic DNS entry ( in this example) for the “SIP Proxy:” field. After saving these changes (and waiting the necessary hour for them to take effect), then calling your IPKall number will directly ring your VoIP phone (bypassing any service provider, including “Free World Dialup”).

NOTE (added 2/7/2006):
Another poster mentioned that he needed to set “NAT Keep Alive Enable: yes“, or he got 1-way audio with his router. So if you are having problems with this trick (and you are not already telling your VoIP adapter to send “keep alive” packets), try turning the “NAT Keep Alive” setting on…

NOTE (added 2/7/2006):
After using this “trick” for some time, I have discovered that (while this often works very well), a minority of VoIP providers just don’t like this setup.

The problem (when you run into a VoIP provider that just won’t forward directly to your VoIP adapter, even though they do support SIP URI forwarding) appears to be with the details of the “dynamic DNS” service. The problem is, there are actually two DIFFERENT types of DNS records often used by VoIP SIP proxies (which is what you are having your adapter pretend to be, by this trick). DNS “A” records are the “normal type” of DNS entries (the type we use all the time, for example when visiting web sites), and also the type most dynamic DNS services (including the service I use) offer. However, apparently there is also a special DNS “SRV” type record that some proxies use just for VoIP. And if your VoIP provider is using a picky enough SIP proxy, they will be unable to forward directly to your adapter, because they won’t find a “SRV” record for your “proxy address” (even though your dynamic DNS service will have a “A” record for your IP). While most VoIP proxies either don’t use SRV records or will happily use an “A” record if an SRV record isn’t present, some proxies are just “too picky” about this little detail (and will therefore fail to forward directly to your adapter UNLESS you have DNS “SRV” record for your IP address).

Happily there is an easy “work around”, if you already have your adapter’s registered VoIP slots “full”, and you want to add a VoIP service that has this “issue” (i.e. is picky about the SRV records). What I found works well (when you run into this problem), was to register for a free SIP Broker alias that points directly to my adapter (via my dynamic DNS address). I then tell any VoIP service that has a problem with forwarding directly to my adapter, to instead forward to * (where xxxxxxx is my SIP Broker alias ). This seems to work well as a “work around”, because “” appears to have the DNS “SRV” record that some VoIP proxies “need” and SIP Broker can forward to a location identified just by a DNS “A” record. So the call essentially gets forwarded to SIP Broker, which forwards the call onto my adapter in that case. While this isn’t quite as nice as going directly to your adapter, it is still an effective “work around” for when the VoIP proxy just refuses to forward directly to your LinkSys/Sipura.

Of course, you might as well try the “forward directly to your adapter” address first, and only resort to the SIP Broker alias if/when the “direct” path doesn’t work (as your call path will be slightly more reliable if the direct address works with your VoIP provider). And many places (including ) will happpily forward directly to your LinkSys/Sipura without any problems. But for those places that just don’t like the DNS “A” records provided by dynamic DNS services, forwarding to SIP Broker (and then letting SIP Broker forward directly to your adapter) can be an effective “work around”.

A Collection of Cheap Phone Services

Intertional Calling

Everybody knows using computers to talk with MSN, QQ etc. We’ll nottalk about those methods here. Instead we talk about calls with regularphones on one side or both sides.

1. Of course, traditional way calling internationally is using calling card.
I went to Chinatown to buy calling cards when I first came here. I bought it online. We can get calling card with rates about or less than 1 cent per minute calling China.

2. Make international calls with local calling rates (or free):

No registration, no credit cards, no catches, no limits!

With talkster, you get a local access for yourself, and an access number for your friend.
Say you want to call your friend, you call your access number which rings your friend’s phone. He/She answers the phone, then hangs up. You stays online. Your friend calls his/her access number. Then you  two will be connected, basically having a conference call.

The good thing about this method is that your friends, families in China call also you by calling their access numbers first. You answer the phone, hang up, ask them to stay online, and then calls your access number.

3. Skype Unlimited World $9.95/month

In particular, unlimited calls areas include:
China landlines and mobiles
USA landlines and mobiles

Make Unlimited Skype™ Calls without a Computer with Belkin’s New Desktop Internet Phone for Skype: $99

Of course you don’t need pay anything if both sides use skype.
Get a skypein phone number, you basically have a lanline phone. It costs €50 one year.

4. There’s another way which is a little bit complicated. But it’s free calling between two sides. You need pay to get sip devices like this: Linksys PAP2T-NA for both sides and connect regular phones to the devices.

Then get sip accounts for both sides, like, or etc. Set it on the Sip device.
Reference: … cked-pap2/


In particular, Freedigits’ account is a US phone number. Basically, you and your friend in China get a free US phone number. Calling between you is free! Of course, other people in US can call you.

If you want to get local numbers, go to, get numbers and forward it to your freedigits number(or GizmoProject sip account).

If you want to call other numbers in US or China, register accounts and buy credit from your favorite VOIP companies like etc, and register it on the sip device.

Basically, you get a home phone with a free US phone number, free calls between you and other people with the same setup and low rate calling to other people.

5. Another convenient way to call China is use Packet8 Mobile Talk with cell phones for 1 cent per minute to China.

6. I guess a lot of poople know iTalkBB. They offer unlimited calls to north America and China with a monthly fee $25.


7. The complicated way is to set up a free PBX asterisk which will provide the most features that you want. You can get a WRT54GS, load OpenWRT firmware and install asterisk. Then you can set up free US phone numbers (or even China number which you usually need pay) to receive calls. And you can set up calling services to call China and US.
