(2) For iPod touch 1st generation users, you need upgrade your iPod to iPhone/iPod OS 2.2 or above and you also need external MIC.

We have tested this app with Macally iVoiceIII external MIC.

(3) SKYPE is not sip protocol, so this app does not support SKYPE account.

(4) Some mobile network operators may prohibit or restrict the use of Voice over Internet Protocol (VoIP) functionality over their network, such as the use of VoIP telephony over a cellular network, and may also impose additional fees, or other charges in connection with VoIP. Please check with your service provider before you use SIP call over 3G or Edge network.

(5)Changes in prefix settings:

Now we have prefix for each account, the prefix for each account only works for calls made from address book.

When the per-account prefix is not set, the prefix in setting will be used, it works for all calls

Don't hesitate to contact our support if you have any questions about this app.

Major issues

It calls the last person I talked to immediately after the other party hangs up. If it lost my sip service at the time, it will use my cell service which costs a lot o money. It does this in the background. I tested other sip programs with the same VoIP provider and this does not happen. Also, the app has major issues with restarting from the background.
