iSip -VOIP Sip Phone

Cheap calls, especially to landlines. Works well. Only problem is that recent calls don't show names of called parties. Use with Sipgate or other VOIP SIPs.

I'm the same. Used to work really well then the upgrade happened at it keeps wiping out my details. When you fix this please let me know.

I have used this app for the past 18 months and it was excellent until this last update came out. It wiped my registration details and, when re-entered, wipes them again each time the app is restarted. It still pushes inbound calls well but, if your settings have been wiped clean (again) you cannot make an outbound call. I have contacted support twice with NO RESPONSE. I have therefore given up with this app. It is more trouble than it is worth so DO NOT BUY IT. It is simply a complete waste of time!

Previous version were fine but I can't get this update to work.

you think its going to be right good then it crashes it freezes and sometimes it doesnt even load up waste of money dont recommend it at all!!!

Were do I start? Constantly crashes or freezes, no sound when using through a VPN connection to my office mitel system. Used 3cx over the Internet and it connects to my system fine (and it's free) isip won't work this way, i brought this app as it has call hold and forwarding deature. Also does not use 3G will only connect over wireless network. Not every phone service provider blocks sip over 3G so see no reason why this is not supported? Besides changing sip ports gets around this block Save you money play with the free offerings

Have been using this for a while, but honestly, the stability keeps getting worse and worse. Each time I use it, it crashes at least twice before letting me make a call (iPhone 4).

Great little app, had it since it's first release and it's been very reliable. Works fine over VPN despite another comment. Would hope for G729 support in a later release.

This app works brilliantly. I have SIP accounts with voipfone and have no problem using this app to connect to them. I've not used it through 3G so can't comment on how well it performs over a cellular network, but the main reason I got it was so that I could make calls over wifi when abroad to keep my costs down and it does this brilliantly. Well done guys, £3.49 well spent.

Just get everything to work and then along comes an upgrade and it stops working again. This happens a lot. For goodness sake test the app before you release it! Where's the plus in the dialing page that is supposed to clear the audio problem? You are up against working free apps so you should get it right!!
