As I did not find any suitable solutions I decided to write my own widget. It's available on Google Play: https://play.google.com/store/apps/details?id=eu.siebeck.sipswitch I also made the source code available: https://github.com/robert7k/sipswitch

You can use CSipSimple to add a local SIP account on both phones without having the need for an intermediate SIP proxy (or server). Add a general 'Local' account. You only have to provide a SIP username for it. When that is done on both phones you can call the other phone: You have to know the IP address or dns name of the other phone You need to know ...

I'm afraid that if the official Skype app does not work then you are probably out of luck. Skype do not let third party applications use their service, so you are unlikely to find anything that works. I suspect the issue is down to the CPU speed of the HTC Wildfire, which is only 528mhz. It's likely that the processor simply can't keep up with the demands ...

Bandwidth consumption depends on the codec that the app will use. Skype uses SILK or G729 (see wikipedia for their bandwidth consumption). You can see here http://searchvoip.techtarget.com.au/articles/23239-VoIP-codecs-Day-Three-Low-bandwidth-codecs more low bandwidth codecs and search for an application that support one of them. I have used SipDroid that ...

Get the pcgod's mumble client for android (don't get it from the market because the market one is not the pcgod uploader and is very old and not updated). Mumble is an open source VOIP client that is available for windows and linux. However, this VOIP is a client-server one , hence requires both the clients to connect to a server. While you may choose a ...

SIP comes directly with the Android system, as you said, starting with Gingerbread. You find it in the system settings: Call Settings, at the very end: Internet Call Settings: For more details, you can also check with the page Android SIP Client Configuration and Review, which explains you all the details. As it comes with the Android System itself, all ...

This is a feature of gingerbread, if you're using the built in sip client. In Settings -> Call settings there is a setting called "Use Internet Calling" which you can set to "Only for Internet Calls". Then if the contact has a sip number, it will call that directly sip->sip instead of going out over the phone connection.

You could signup for Skype and get a Skype "Online Number" (this used to be called "Skype In") and then install the Skype app on your phone. This would give you a real phone number that anyone could ring from a normal landline or mobile, that would ring through to Skype on your phone (or any other device) over your data connection.

I have an HTC One, and even though I cannot deduce why, my settings menu did not display options for SIP setup until AFTER I unlocked the bootloader. I will clarify that ALL I did was unlock the bootloader, I did NOT flash a new ROM. Again, this makes absolutely no sense, but it worked for me.

You can use sipdroid, released under GNU GPL v3, also available from Google Play Store and save yourself a lot of trouble. sipdroid is a free SIP/VoIP client for Android. As for a SIP provider, Sipgate for example gives good results for both outgoing and incoming calls. From version 2.0 For Google™ Voice users, Sipdroid can now create a new, free ...

You might want to take a look at Asterisk, an open source PBX. You can create a dialplan that will ring your Skype or sip address first, and then switch to your prepaid phone number. With version 1.8, Asterisk supports Google Voice in addition to Skype. Dialplans are completely configurable, however this does entail setting up a server to run Asterisk. The ...

I believe it is the CPU speed. The HTC Wildfire has a CPU speed of 528 MHz. The Skype app is only supported on devices with a CPU clock speed of 600MHz or greater. See the section on 'What do I need to run Skype on my Android phone?' https://support.skype.com/en/faq/FA10653/How-can-I-get-Skype-on-my-Android-phone

Yes if you use a VoIP app and your cellphone service provider lets you divert your number on no connection - but remember that you will bear the cost for the diversion. If you want to just have a wifi-based (VoIP) number that's separate from your cell number then any VoIP service provider will be able to do that - I have a test VoIP setup on my HTC Desire ...

You could use a VPN to "mask" all your traffic. This way your provider would still be able to count the amount of data transfered -- but he would no longer be able to see its contents. VPN requires a client (which comes already integrated with recent Android versions -- but additionally, there are a lot of apps available for this on the Google Playstore) ...

You can use your Google Voice number and receive calls at any computer. The following snip comes from Google's web site for Google Voice: Make and receive calls in Gmail Google Voice lets you manage all your phone communications and seamlessly make and receive calls on any of your existing phones. But what if you don’t have your phone with you? Or ...

At the time this question was originally asked, Skype Lite was the only official Skype client and it was locked into the Verizon Network and it locked voice calling to wifi only (so as not to compete with their cell minute plans). As of early October, Skype released it to the Market for phones on other carriers. It was still crippled from making SkypeOut ...

Use uSipServer + SipDroid (or whatever SIP client) configured at an explicit IP address. Like one device has uSipServer, started Wi-Fi AP (in "Tethering" menu) and SipDroid connected to test1@127.0.0.1. Other device connects to Wi-Fi and use SIP account test2@192.168.43.1 and calls to "test1". Update: Have just tested that this configuration actually ...

It's not possible to have the same number on two different phones. On your Nexus S, you could install Skype. That will give you FREE VOIP for Skype-to-Skype calls. You don't need a number for this, just an internet connection (and a Skype account, which is free). Take note, however, Skype to mobile / landline is not free. For other alternatives, search for ...

The Answer to the question is Yes and I do it. I use a Raspberry Pi running RasPBX so within the house most things are SIP or DECT. My Main phone is a Gigaset DX800A which supports SIP and also DECT. These DECT phones attached to the DX800A become SIP extensions. The Phone in my office is an Aastra 6739i (SIP) with a Sennheiser DECT headset. I have a ...

While I've not tried to use my phone like this myself, I found the question interesting enough to do a little googling. The best search term seemed to be android wifi|bluetooth walkie talkie. The most promising free candidate I found looks to be Android Intercom - direct phone to phone communication over wifi or BT without an intermediary server or telco. ...

There is a SIP client built right into your phone (Gingerbread and above). You can find this either in general settings, or in settings for the phone dialer app. E.g. in Jellybean: go to the phone dialer page (as if you were going to make a call) choose the menu (bottom right vertical "...") tap Settings Scroll down to "Accounts" and tap it. enter your ...

Even if the other AP connected, you will lose your call. When you switch access points, you are going to drop the wi-fi call. The device may have a hard time figuring out if it should switch to AP2 because it is still connected to AP1 and it can still see AP1. if the signals overlap, it will connect to the strongest one at the time, if it is already ...

Android 2.3 natively supports SIP, which means that it's compatible with most VoIP providers. It's as simple as configuring the account at Settings > Call Settings > Internet Accounts. If you cannot upgrade to 2.3, consider trying different SIP clients from the Market (unfortunately I don't have a good recommendation).

There are a number of sip clients available such as Sipdroid, CSipSimple, and Linphone. Sipdroid includes an option to create a pbxes.org account linked to your Google Voice account, allowing you to make and receive calls to and from PSTN numbers for free, assuming you are in the US. (After the account is created, any sip client can be used with the ...
