[Acer Iconia Tab A100] linuxsociety:
I can use my A100 perfectly fine with Sipdroid and my google voice account, however the problem is more or less a convenience issue. Sipdroid doesn't have a good way to view your contacts like in an address book, and it also doesn't dial from the "People" app when you try to place a call using sipdroid. I have had other android devices that the contacts(now People) will allow you to call a person from the internal dialer or a 3rd party one and it automatically forwards the call to sipdroid accordingly. I installed the Dialer One app hoping that it would solve the issue on my A100, and that is when I found out that it didn't work at all with it. I get a message saying "Telephony feature is unavailable on this device" I have had other tablets without telephony capabilities that this app has worked with. I am wondering if there is a simple mod I can do to trick the app into thinking it does have telephony capabilities, or if there is some way I could recompile cm9 to include any missing libraries, system files, apks, etc.. such as the internal dialer. If anyone has got Dialer One to work for them with SipDroid +GV or if you know of an app that works like the default dialer app (that we don't have) then please let me know. I appreciate the help. If I can get this figured out I'll make an attempt at providing a custom ROM with the dialer and telephony features enabled just for people who wish to use Google Voice calling with their tablet. If it is as simple as a build.prop edit then I will add that to my custom build.prop in my thread at http://xdaforums.com/showthread.php?t=1799148

**Edit: I think I found a solution to get SipDroid to place calls when calling from "People(contacts)" I was looking into the process that takes place when a call is initiated and I seen that we have a Phone.apk in our a100 roms, but the process is nullified so nothing ever takes place when something triggers it.

I had the idea, well what devices that are tegra2 based have ICS and allow phone/voice calling? Motorola Atrix 4g does.. So let me find the Motorola Atrix 4G Phone.apk and replace the one I have in /system/app/ with it. Lo and Behold I can now make calls directly from my contacts!! This fixed it, partially.. What still doesn't work? Dialer One still gives the same error - "Telephony feature is unavailable on this device", but now I don't really need Dialer One anyway since I can just use the builtin contacts through the People app. Another thing thats not really desired, once you make a call you will get a blank window for the Phone app at the bottom of your "history" list (button beside the home on the launcher) I will try to figure out a way to get rid of this annoyance and prevent history from ever showing the Phone app.

If you want to try it your self, here is what to do (you must be root):

If you have Android ICS 4.0.3 or newer Download the Motorola Atrix 4G Phone.apk here. **If you are using HC then you will need the Phone.apk from a Tegra2 device that runs HoneyComb 3.x**

Mount /system writeable

Move the file /system/app/Phone.apk to /system/app/Phone.apk.bak

Put the downloaded Phone.apk in /system/app

Touch the phone number for a contact in your "People" app

Choose to call with SipDroid (or other app in list that accepts the dial function)

Watch the call take place (you may want to try dialing someone you know you isn't going to answer the phone or wonder what you are doing haha)

**Please note that this does not enable the "Call/Dial" app to show up in your applications, it simply allows calls to be passed to a Sip dialer such as SipDroid**
