Proxy servers that I know of:

Code: Select all

proxy1.Atlanta.talk4free.com
proxy1.Austin.talk4free.com
proxy1.Baltimore.talk4free.com
proxy1.Boston.talk4free.com
proxy1.Chicago.talk4free.com
proxy1.Cleveland.talk4free.com
proxy1.Columbus.talk4free.com
proxy1.Dallas.talk4free.com
proxy1.Denver.talk4free.com
proxy1.Detroit.talk4free.com
proxy1.Houston.talk4free.com
proxy1.LasVegas.talk4free.com
proxy1.LosAngeles.talk4free.com
proxy1.Memphis.talk4free.com
proxy1.Minneapolis.talk4free.com
proxy1.Nashville.talk4free.com
proxy1.NewYork.talk4free.com
proxy1.Newark.talk4free.com
proxy1.Philadelphia.talk4free.com
proxy1.Phoenix.talk4free.com
proxy1.Pittsburgh.talk4free.com
proxy1.Portland.talk4free.com
proxy1.Sacramento.talk4free.com
proxy1.SaltLakeCity.talk4free.com
proxy1.SanDiego.talk4free.com
proxy1.SanFrancisco.talk4free.com
proxy1.Seattle.talk4free.com
proxy1.StLouis.talk4free.com
proxy1.Tampa.talk4free.com
proxy1.Washington.talk4free.com
If you want to use the SanDiego proxy, you would need to find it's IP address, and hack something into the hosts file.

So, do:

Code: Select all

nslookup proxy1.SanDiego.talk4free.com
This will return the IP address 67.111.81.6.

Now, determine the proxy that you are using. (You can do this with Fiddler or any network sniffer like ethereal.) So, if you are pointed at proxy1.nashville.talk4free.com, you can add a line like this to your windows hosts file:

Code: Select all

67.111.81.6 proxy1.nashville.talk4free.com
I think that should work.

Why do you want to do this anyway?

When one proxy is down, it's often possible to use another and continue running. You may also experience lower latency with another proxy, especially on incoming calls. Problem is, inbound calls from PSTN are unreliable or don't work at all with some proxies. I don't know whether this behavior is a function of which POP site hosts your number.

Edit: There is currently no normal Miami proxy, only a "lab" proxy, presumably a test server. Thanks to MagicHack for pointing this out.

You can just ping them, no need for nslookup.

Previously unlisted proxy?

Post by asragov »

Hello.

MagicJack seems to be connecting in my case to prov1.talk4free.com (as listed in Fiddler2).

85ms latency!

However, I am in San Diego, and pinging the San Diego proxy is only 30ms.

How best to change this? I didn't have luck with the hosts file - it seemed to persist in trying to connect to prov1.talk4free.com

That is the provisioning server you are looking at, not the proxy server.

prov1.talk4free.com is not a MJ proxy server but a provisioning server. You don't want to mess with this one. Make an incoming call or outgoing call then check the network monitoring tool to see which proxy server your MJ softphone is using.

Dare I ask... But i was wondering where is the windows host file located at? got a 401/402 yesterday all day. Wondering if changing the proxy server would help?

I tried re-homing myself from the NY to the Baltimore proxy. Not only didn't it work, it locked out my MJ. I changed the hosts file, rebooted, and MJ gave me error 401 and error 3. Looking at the network traffic with Wireshark showed that the SIP authentication was failing at the Baltimore proxy.

OK, I removed the entry from the hosts file, rebooted, and tried to restart MJ against the NY proxy. Same problem - SIP authentication failures. I had to get tech support to (as he said) "refresh" the account.

Unless this was just a total screw-up on their end, it looks like MJ is tightening down on this sort of proxy movement.
