Acer iconia tab A500 SipManager.isApiSupported returns false (Voip api not supported)

Tablet: Acer A500 GEN1 Android 3.1 kernel 2.6.36.3 (API level 12)

SipManager since API level 9

Nowhere in the device specs I could read, that there is no Voip support. Last week tested my application on Galaxy 10.1 tab and everything worked fine.

Here are the requirements for developing a SIP application:

You must have a mobile device that is running Android 2.3 or higher.

SIP runs over a wireless data connection, so your device must have a data connection (w开发者_运维知识库ith a mobile data service or Wi-Fi). This means that you can't test on AVD—you can only test on a physical device. For details, see Testing SIP Applications.

Each participant in the application's communication session must have a SIP account. There are many different SIP providers that offer SIP accounts.

My device meets all the requirements.

What the hell?

I can't find the reference, but it seems to me that Acer has turned off the Voip support deliberately. I solved this problem by rooting my device and installing Galaxy Tab 10.1 ROM.
