specifying an intranet proxy
Stewart:
If GV through Gmail works, the UDP ports for RTP must be unblocked (I seriously doubt anything could be proxying them). So, I'd expect PBXes (on port 36999) to work; standard SIP might also work.
Does your OBi show the correct date/time (in some timezone) in System Status? If not, there is something wrong with the Internet setup. Does it have a valid gateway, DNS servers etc?
I don't know why OBiTALK is not working. Do you have a SIP account set up in the OBi? What does it show in System Status?
Assuming that it has its own DID, you should be able to call from your school phone using any service with click-to-call. For example, using Localphone calling the US, you'd pay $0.01 or $0.012/min. for the China leg, depending on what city you're in, plus $0.005/min. for the US leg.

about the system status, how do i see that in obitalk configuration on my profile? i had the obi device added before i left america. now, when i click "Add an OBi Device", i key in the code via the phone interface, and the autoresponder says "the key was sent to the server" (or something of that sort). but, the countdown on the wizard doesn't stop like it did when i added the obi when i was in america. so, i think the code is never getting sent to the server.
i want to reiterate that in order for me to use the internet on my computer, i have to specify a proxy address in my internet settings. otherwise, i can not connect to outside sources. so, since i am not specifying this anywhere in my obitalk configurations, i think this is why my obi device is probably not really sending the code to the server, but it may be.... obitalk never shows my device found though after i've typed the code then hearing that the code was sent to the server.
when i had the obi device added when i was in america, i did have GV setup as the sip account. above mentioned shows that i removed the device and tried to readd it from a test i saw in another thread. so, i don't know how to check the system status if i don't have a device listed.
the power light of my obi is solid green and the internet light has a series of multiple green flashes every few seconds.

i found out about checking the system status. dialing *** 1 worked to get the intranet ip of my device, and i connected to it and see:
ModelName OBi110
SerialNumber 88B01NA00FPF
OBiNumber 200 883 878
HardwareVersion 3.4
SoftwareVersion 1.3.0 (Build: 2651)
SystemTime 16:29:40 01/01/2010, Friday
so, the date is not accurate, but the time is.
Stewart:
I'm puzzled about the time, becuase NTP sends both date and time in the same long number, so it's hard to imagine how the date could be wrong. Possibly, the time being about right was accidental. Did you change LocalTimeZone for China? If not, the time isn't right, anyhow. You migh try cycling power, waiting a minute for it to boot completely and see whether the time is still correct.
GV is not a SIP service. I don't know whether the XMPP protocol it uses may conflict with the (lack of) proxy on the OBi. Get a free Callcentric or PBXes account and test whether it works correctly in X-Lite on your PC. If so, try that on your OBi and report results.
For Callcentric, test by calling 17771234567 (should ring TellMe).
For PBXes, if you just set up one extension, you can reach the echo test on *43. If connecting to the standard port 5060 fails, try port 36999.
matthewk:
would the IP Freedom ("Unlimited free calling between all Callcentric members with no monthly fees.") work for callcentric for this test?
downloading x-lite (http://www.counterpath.com/x-lite-download.html) to try.
