VOiPover3G for Android????

There is an iPhone 3G app called VOiPover3G that tricks other iPhone apps into thinking that they are on Wi-Fi even though they are on 3G/EDGE/GPRS.
Is anything like this being looked at/developed for Android phones??

Please post questions about apps in the correct subforum. This will probably get locked...

This probably is the right subforum. Apps forum is for apps that have been compiled and released. This forum is for dev including apps dev.
Anyway, what would be the point in a program like that? What programs could benefit from it?

It would allow programs like sipdroid (the market version) to think it was on wifi and when we finally get something like Fring for Android that would also be able to use the data package to make voip calls, even "real" skype calls.

It is in the wrong part of the forum, but I might as well answer it...
While the iPhone doesn't allow certain services over 3G (e.g. VoIP stuff), the current Android handsets + apps don't do such a thing.
e.g. Sipdroid works fine over edge/umts/wifi (as good as those networks can support VoIP).
It's really kind of a strange question to be honest. If there isn't a problem, don't ask questions about it

Not to harp on the point made by Diceman4, but it really isn't the correct sub-forum. If you look at the Stickies in the Apps/Games sub-forum, you will see that one of them is regarding request/ideas for applications.

I don't see any development going on in the first post though. This seems more like a post for the "ideas for apps" thread in app subforum. Although if the op came back with a chunk of code that needed debugging, that would be a different story.

MOD EDIT
Moved to Applications & games forum

The main reason for asking was because of problems with Tmob in the UK blocking sipdroid (port 5060) and preventing it using 3G etc.
If we had an app like VOiPover3G it may very well allow us to bypass that problem, I don't know

Why? a better bet would be to ask the sipdroid creator to include a user configurable port setting. The point of android is that the workarounds don't need to be workarounds on the phone, but rather workrounds for interfacing with the network.

The technique described by the op routes traffic internally from the wifi interface to the cellular interface. That will have no effect on the protocol or port used. In other words, it will only be of use if the app is hardcoded to use wifi only and you want to work around that. If the cellular carrier is blocking the data, this method will not get around that.
As for sipdroid, you can manually configure the port used.

If you use pbxes there are a handful of different ports that will work but I haven't been able to get any to work. Saying that, up till recently I was using Gizmo5 but pbxes have blocked it's use after they (Gizmo5) allegedly stole/used sipdroid code and renamed it as if it was there own.
If any one has had success with sipdroid on 3g etc on t-mob UK please post the sip provider and the settings used.

Have you guys tried using the FULL version of sipdroid.. the one on the market didnt allow for 3g calls but this one does http://code.google.com/p/sipdroid/

Been there, done that, even got the T-shirt.
The problem is T-mob in the UK are a pain in the neck and are blocking the port 5060.
As someone has already mentioned in this thread, what is needed is a user configurable port so that T-mob UK can't block.
Let's hope sipdroid developers can do something along those lines.

I don't get it... have you tried all the alternative ports listed in pbxes website?
53, 69, 80, 135, 161, 443, 500, 1433, 1701, 1812, 3389, 4500, 5061, 5900, 16999, 26999 and
36999 (recommended)
Note:
Because of the DNS entries for pbxes.org your device may be selecting port 5060 automatically. If you want to use an alternative port enter 188.40.65.148 as SIP server.

Both of them work as UDP or TCP.
TCP is recommended as it will help with battery life.
If none of these ports work, then It has to be that T-mobile has a Layer 7 filter in place looking for the SIP signaling traffic, and there should be no workaround possible unless you can wrap your sip traffic in a VPN. Nothing can be done to stop that, unless they filter the whole L2TP,PPTP,IPSEC or OpenVPN protocols.

I have tried most if not all of the ports specified and still no joy BUT I'll give it another go. What SIP provider do you use?
If T-mob are killing all SIP traffic how is it possible to use sipdriod over VPN?? Surely that is a major undertaking?
If it was done though, it would be the most robust and bulletproof VOIP app and would never be stopped Brilliant

I have just tried every single one of the alternative ports and every time I had a registration failure (timeout) so I guess T-mob are filtering for SIP traffic.
That leaves only the VPN route OR change providers OR change phones.

Changing phones WILL NOT work since it isn't the phone that is causing the problem, it is the provider.
VPN should be fine, but you'll need a VPN server somewhere to connect through, i.e., your home computer.

There is nothing a carrier can do to block SIP over VPN. Everything is tunneled over the VPN connection so they can't know what goes in there.
As soon as we have a reliable VPN service (Donut seems to have PPTP or L2TP, although I'd love to see OpenVPN there) , you'll ve able to set-up your own voip and vpn server and pipe all the voice through it.
There is a couple of VoIP providers who can do that for you. One that comes to mind is callwithus.
On the connection issue with t-mobile, I suggest you try this:
If you have a DMZ linux/cygwin (altough a windows box might make it) host or a shell anywhere you can test if your provider is locking those ports, the pbxes ip or maybe even the SIP traffic.
Listen in a port using netcat:
netcat -n -l -vvvv 5060
Click to expand...
Click to collapse
Launch the Terminal Emulator in your android phone and test if you can connect to your host:
nc <your_hostname> 5060
Click to expand...
Click to collapse
Type something... if you can see the text, they have a L7 filter in place.
If you can't see anything, they are blocking the port.
Now change the listening port to 36999 for instance.
Try to connect again. It should work.
Now in Sipdroid, add your hostname, give it any username, any password, use the 36999 port and select TCP connection and keep the netcat running on your listening host.
If you see a connection in your listening host and some signalling traffic, pbxes should work for you.
If you don't, then there's a really advance L7 filter between you and the internet and they can block anything they want to.
In this case, the only solution (and there's nothing they can do unless they also block it), is to use a VPN.

Thanks guys for all your suggestions. I'll try and go through all the procedures you've suggested stickman and I'll post the results

wifi vs data prob: perhaps an answer from dev sect?

In need of help again, very sorry.
using froyo 2.2 on an ATT vers Nexus One.
Problem:
So with using the default browser (mozilla?), as well as Dolphin HD browser...there are a few important sites I cannot load (no matter what) via 3g or 2G data.
It tries to load at first but just quickly stops leaving me at a blank page.
However, if i switch to my wi-fi network, these same problem pages will load without issue. Not a problem.
But switch back to mobile data 2G or 3G...these sites will not load.
All other websites I visit (so far) load fine either wifi or 3g/2g, it's just some specific ones. This is a constant and consistent problem with specific websites.
The sites are
- hotmail
- ebay mobile
* but I'm sure I'd find others.
So it's strange...perhaps this is best asked in the dev section?
I have no idea what to search on this problem (here or google).
It's as if something is out of whack at the browser end, like it's reading some form data that I could fix/edit/delete and resolve this problem. Or perhaps it's some security bug/issue...
Either way, I need to get this fixed so I can check hotmail if I need to while on the road, ....problem is I don't know where or what to do here for a fix. Any suggestions?
Certain config file, or the like I can edit or del for a fix?
I've DEL the cache, form data, cookies, etc...everything. No fix.
Can the default browser on the nexus one be uninstalled/reinstalled?
I know I can uninstall/reinstall Dolphin HD, I'll try that.
I also like the default browser though...any way this can be fixed?

man, this problem is getting worse...and it's happening in other browsers too.
dolphin and opera.
it's as if there's a glitch that occurs if you once viewed a site via wifi...then when using 3G it has hang ups (blank load screen).
Is there anyone who might have an answer here?
Can the built in browser be reinstalled (froyo 2.2) to try and fix?

Works fine for me.

?
I'm sure it does, and that's great. Most pages load fine too here...but...
As mentioned it seems to be more of an odd or rare "glitch" here...like something that goes awry under special circumstances (won't load a certain page under 3g/2g data - but will load same page using my wifi).
Now it's happening with facebook in default browser and dolphin. Seems to be happening due to usage at home (wifi)...then accessing same via 3G/2G (not at home). Some hiccup...causing a no load scenario with cell data (no problems via wifi though).
Can we please only reply if this is something you also encountered or may know what's going on here?

I'm no expert but the sites you described seem to be https sites, a secured version of normal webpages. And you're trying to acces those sites through an unsecured data connection 3G/2G.
So I don't know exactly what https does but I assume it won't allow you to send/receive your data over an unencrypted network.
But as for your hotmail problem, you can configure your stock e-mail app to receive your hotmails.

This definitely is the wrong section to post this, you might get a lot of flack for posting here!
Try installing a new rom, your issues are not normal. Try Enom's newest -- it has a stable kernel, and offers perhaps an updated apn file. Short of that, you need to call your cellphone provider, and find out the apn settings from them (double check), and/or why they are restricting access...
I understand your frustration with not getting a response in the Q&A section, but the dev section is for devs and testers. Maybe look at what distribution of froyo you are running (cyanogen? enom? kang-o-rama? leo?) and post in their respective threads. and if this is just a stock updated froyo, you definitely need to call your cellphone provider.
Good luck!
Also, note the rules: http://forum.xda-developers.com/showthread.php?t=614062

verify your APN settings. Same thing happened to me & proper APN settings fixed it.
Not sure the proper ones for AT&T, however.
edit: make sure to clear anything that ought to be cleared -- an asterisk isn't the same as cleared

Delete your Proxy IP and Port under APN settings and try to reload the page.

As mentioned above, 1) this is wrong section, 2) if you're on a custom ROM - try another ROM, and if you're on stock FRF91 or any custom ROM does the same - then it's definitely a problem with your cellular provider and/or your APN settings.

It may pay to check that it's not your carrier.
Can you access those sites with your SIM in another phone?

Merged threads ... please do not create duplicate threads as it clutters up the forum and invites flamming/trolling responses.

Android OS using data

Hey!
I'm getting crazy here...
I do not have an internet flatrate on my phone, everything is prepaid, i.e. every time I access the internet via mobile data I lose money !
My provider lets me access facebook for free -> I sometimes use it on the go.
Eventhough its free I lose money through "Android OS" downloading stuff...
I'm using Droidwall and only allowed Dolphin to use mobile data. Android OS still has access somehow...
Does anybody know how to stop Android OS from using data? I don't have any syncs on. Even when using the option "restrict background data" i lose money though Android OS. My Data Manager also just tells me "dolphin" and "OS services"...
Hope you can help!

Sorry but this wont help me. I need a diagnostics tool that tells me which app exactly eats my money. Whenever id turn on the apn androidos would still download stuff. I nearly never have mobile data on.

Thanks for trying to help but you cannot imagine how often i do a factory reset. This does NOT fix the problem of Android OS.

Have you enabled - back up my settings, etc. to my google account ?

In most ICS Rom are widget buttons where you can find "Toggle sync". Disable synchronization by this widget doesn't help?

Its driving me crazy! :/

Hmm, if you switched off general synchronization and it doesn't help, maybe try switch off synchronize in every application, e.g, weather, google play etc.
It's a bit strange, but maybe it'll help

Don't know if that would help, since i use Droidwall to block all internet accesses on mobile data exept Dolphin. AndroidOS still has access but i cannot figure out why...
Which processes are AndroidOS? Is there any Spy App that could tell me this?

Hmmm.... use a DroidWall from Google Play, if your phone is rooted.
After install, you can precisely set which app would you like to grant net access, and it is possible to allow access over wifi only.
Another what you can try is PermissionsDenied. Here you can set the net access via each app permission.

Now Im saying it thrice. I am using Droidwall!

AndroidOS is still eating my money...

I guess it's not much solace, but I'm experiencing the same. I know a bit about Android/Linux/etc., so I took a look at the firewall rules. Theoretically it is possible that some packets are leaking through the rules of DroidWall (or the firewall rules of "avast! Mobile Security" ... but they are mostly the same as DroidWall's rules). Later I'll test this by adding a custom rule that logs everything that gets past DroidWall's rules and see if any traffic shows up that should be caught by DroidWall. I'll report back my results here.

Ok, I got to the bottom of this. In my case I was seeing very small amounts of data usage and it was attributed to the "Android OS" app/component in the "Settings / Data usage / Mobile" screen. As it turned out, the small traffic was caused by regular DNS requests (since I had "avast! Mobile Security" installed which always allows outgoing DNS requests ... regardless of your firewall settings).
I wrote a pretty thorough post on my experiences in my blog: muzso.hu/node/4943
P.S.: I do not have yet 10 posts on xda-developers so I was not allowed to insert a proper link to my blog post (but I guess a copy&paste is not too much to ask for if you're interested in the details)

Malware wonderlandads on xperia z3

Hi, i'm sorry first for my english and second for writing this thread in this discussion because i don't know where to put it.
I have a great problem on my sony z3. When i use any browser on my device, when i scroll down it appears a pop up by wonderlandads that redirecting me on other apps download.
I don't know what to do because it's not my router's fault, infact when i use my device with mobile data it happens anyway.
Please you are the only one that can help me, i've tried so many things (change dns on my router, 5 different antivirus, delete data on phone and sd, the last thing that remains is an hard reset and i red that this doesn't work for other people) but nothing worked. If you are interested i can send an email of my home screen recorded.
Thank you.

Identify what apps you have installed on your phone. Probably one of those causing this.
My advice: Make a backup, then make a factory reset. If that solves it, it's one of your installed apps causing the issue.
Also just by the way, this is the Z3 Compact part of XDA, be mindful of that when posting further! (And welcome to XDA!)

I suggest using AdAway, It adds almost all the ad servers to your host files and redirects them 127.0.0.1 which is your own device so you don't get any ads.
Also try avoiding shady websites when downloading apks
Just do a clean wipe and everything should return to normal

Question How to block app from internet?

I'm trying to find a way to completely block a single app from connecting to the internet. I'm playing a mobile game and want to start a new game, but when i delete cache/data it automatically loads old profile when I start it up. This game has no option to change accounts. The only way I can start a new game is if I turn off mobile data, but as soon as I turn it back on my new save immediately gets overwritten.
The only two options I can seem to find is to go into an option that was removed in Android 12, which was go into data saver options, or download some app called "netguard" which conflicts with my current VPN. Is there another way I can block this app from the internet?
