<div>I would like to setup an iphone to be an extension on my pbx. I have looked at SIAX as well as Asteriskc2d. Does anyone have any experience with either of these or another app? The important thing for me is that I can run it in the background so I can always be available to receive a call. It has to work over both 3g as well as wifi so I can take advantage of my data plan and not use minutes on my phone.</div>

<div>Thank you in advance for any info you may have.</div>
