I've been using FreeVoipDeal to make calls to Israel for a while. I can access via a local access number, or via an iOs app.
However, recently the iOs app (probably most recent update) seems get me calls with no voice. Also, I need to call a company in Israel, and it doesn't seem to allow me to navigate using touch tones (seems like FreeVoipDeal doesn't transmit them correctly).
I also have an Anveo.com account, which I can use as backup for calls to Israel (2.7 cents per minute to mobile) but in order to use on my iPhone I would need to install a SIP client.
Obviously I prefer free, but most important is 1. reliability and 2. Not being a resource hog on my phone.
Any recommendations?
