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.

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 ...

Do you have an app called "Voice Changer" installed? I've read that it can cause this. Also if you have google voice installed, do you have it set to "Never Dial with Google Voice"? If those are not the cause, do you have any other "Phone Linking" apps or "Sip Dialers" etc, remove them and see if your issue stops.

As for a SIP provider, Sipgate for example gives good results for both outgoing and incoming calls. From version 2.0 For Googleâ„¢ Voice users, Sipdroid can now create a new, free ...

If you are using your Google Voice for another purpose, such as a SIP service for an ObiHai appliance or as a VOIP system on your PC, you will encounter problems with Voicemail not picking up. You will need to disable Google Voicemail on your phone, create a new Google Voice account, with a new number, and add your Android phone to that account. Then select ...

I don't know but may who is expert in sip stack or have time to do can implement missing functionality but I am neither one of them so my desire to get an ...

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 ...

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 ...

That sip settings are hidden in "activities" below "Telefon", it took me a while to find it. Creating a SIP Account was possible but it was not stored permanently. After closing the sip settings and opening it again it's gone. Still using Vimtura Vimphone as sip dialer. LG P880 fw v.20b, Android 4.1.2

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 is an opensource application Sipdroid, which theoretically could be modified to do proxying. But, judging from the poor general Android SIP experience, I'd think it would be very unreliable solution. Easier way to workaround greedy cell providers seems to set up an IP PBX on the home computer, or get a free account at freepbxes.org and get a cheap ...

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 ...

This would seem to require device in which the in-call audio can be sourced/obtained by an application. On the typical android phone architecture, in call audio is handled by the radio co-processor, entirely out of reach of anything running under linux/android - the same reason why you can't really record calls. If you got a rooted phone with (or hackable ...
