Top Pcmac Reviews

Very satisfied

By Joe Dobish (Pcmac user)

I've been using SipPhone with Callcentric and it works very well for both inbound and outbound calls. So far this is the best SIP/VoIP application I've seen for the iPhone. If the following could be fixed/added to the app it would be 5 stars: 1. Doesn't show caller id name on inbound calls; even though I see this is being transmitted to the app. 2. It's a little slow to open/load the App; it takes about 10 seconds on my iPhone 3G. Would be great if it opened in just a few seconds. 3. It would be great if it supported the G.729 (lower bandwidth) codec; although I think this might be a licensing issue. 4. Call waiting. Currently you can only receive 1 inbound call at a time. 5. The voicemail waiting indicator (and access to voicemail) could be a little easier to use. 6. The voicemail waiting indicator won't update unless you close and re-open the app; when this does work on other soft/hard phones I've tried. While the above would be nice to get fixed, overall I have no real complaints. Thanks for the great app.
Best Quality VoiP Application in the App store to date!

By PhilDrenke (Pcmac user)

This VoiP application so far beats everything out there including TruPhone and Fring. I was looking for an easy to use VoiP application with voice quality and easy use being the most important factors to me. At first I was a little hesistant to spend $7 on a small app like this, but the voice quality I got in return for this is truly amazing - a clear advantage compared to Fring. And unlike TruPhone, you don't have to use their SIP Service, you can just choose whichever SIP provider you like. It was very easy to set up and dialing straight from your address book works like a charm. Compared to Fring you also don't have to wait until all your services are connected. The app takes like 3 seconds to load and you can dial right away. The only things I personally dislike are the look of the interface. I wish it would blend in more with the iPhones native applications. Preferably I would like everything to look like the iPhones regular dialer. And setting your caller ID to your regular cell phone number would be nice. Of course making those iP calls using the 3G network would be even better, but unfortunately as we all know this is not something Apple's Mobile Phone partners would like to see which is probably one reason this is not included in any of the VoiP apps that are currently available for the iPhone.
It works great!

By HoyttGringo (Pcmac user)

I have used it for a couple of weeks. I set up my Voipon (UK) account and incoming and outgoing calls work perfect in both 3G or Wifi. When I receive a call, if the app is closed, I will receive a Push Notification, allowing me to take the call. Even when I am in the street connected by 3G. THAT IS GREAT! Support have answered promptly to me when requesting some information about the acc config. Some times, when 3G is not very good the quality of the voice decrease. (It's logic). The Developer needs to keep working on the UI (I think is very poor) and also the ring tones options. Other than that, for the moment the best Voip App I have tried.
This app works but you need to configure it properly

By maxi123 (Pcmac user)

I downloaded this app and it didn't work properly; Audio was so choppy that it couldn't be used (even on the same network than our Asterisk Server). Also under some conditions and I only got one way audio. I spent a complete day doing several adjustments and debugging the protocol to check what was happening. The application is now working fine (audio is good; Not excellent, but good enough). If you are planning to use this application; You must have really good understanding of VOIP and what is happening under the hood. For example; I am not a big fan of this app VAD implementation, I had to turn it off. Remember to set the stun servers if you are planning to use it behind a NAT; there are a few free stun servers on the internet. PUSH did work OK to me; although I can't answer the call when receiving the notification. IMHO there is room for improvement on this app. Buy it *ONLY* if you really know SIP protocol and you are willing to spend some time to configure/debug it to make it work correctly on your enviroment. *** Please add g729 support ***
