Mobile VoIP

mobile VoIP iphone & android

Take your OnSIP business phone service wherever you go. OnSIP works on soft phone applications for smartphones, allowing you to stay connected, even when you're nowhere near your desk phone. Your mobile phone becomes your office extension, displaying your company caller ID on outbound calls and allowing you to enjoy features like extension to extension dialing, and more *.

Please note that performance is entirely reliant on the mobile soft phone you choose and your Wi-Fi or 3G connection strength. We do not suggest this solution as a total replacement for your desk phone.

* While most mobile VoIP apps are great for making and receiving calls, very few, if any, can perform all the functions of a desk phone.

Mobile VoIP App Reviews

Because each mobile VoIP app is different, our team conducts thorough reviews to make sure you are buying and/or downloading the right one.

iPhone VoIP Applications

"Groundwire for the iOS by Acrobits, a mobile software company focused primarily on SIP clients for mobile devices, is the business version of their Acrobits Softphone. Marketed as a viable replacement for your desktop phone ("Throw away your desktop phone, Groundwire is here."), this mobile VoIP application includes many of the features you would expect to find in enterprise VoIP software or SIP hardware devices..."
"One SIP client that we have kept our eye on for a while now is Media5-Fone from Media5 Corporation, a provider of “Secure, Survivable MMoIP Branch Office Solutions for Service Providers”. The company has released a series of updates to the Media5-Fone over the past couple of months, turning it from a basic calling application to a full-featured soft phone. Apple recently approved version 2.4.1.9 for the iPhone, iPad and iPod touch, and here are a few of our initial thoughts..."
"Built only a week ago, Bria iPhone Edition version 1.0.3008, has a lot of competition in the mobile VoIP app market. There are probably no less than a dozen similar apps, each of them months ahead in terms of the number of updates and upgrades. The good news is that Counterpath included pretty much everything we wanted in their first version. While other publishers started their apps with the very basics (making and receiving calls) and added additional features slowly over the weeks and months, Counterpath crammed almost everything we could possibly want in their first version..."
"The Acrobits Softphone is a mobile SIP application for the iPhone platform. It is one of the higher rated applications we’ve encountered in the App Store (4 out of 5 stars last time we checked), which is a good sign. We’ve been looking around for a great desk-phone-replacing mobile application for a while now; one that has all the normal calling features you’d expect from a business phone, and allows you to be reached on your mobile device when someone dials your extension..."
"iSIP 4.4 is a completely different mobile VoIP app than the one we tested back in 2009. The look is still mostly the same (iSIP isn’t nearly as pretty as Acrobits), but a lot has changed under the hood. For one, the application now works over 3G, which is a must-have feature in our opinion. A mobile VoIP application that relies on Wi-fi is pretty pointless if you ask me. iSIP also supports call transfer and golly gee willikers, Batman!—it actually works pretty well..."

Android VoIP Applications

"CSIP Simple is a free SIP client for Android, great for making and receiving calls. There currently isn’t much support for much else beyond that in its current build, but if you cannot remember the last time you used your transfer button or the last time you had to juggle 2 callers on your cell phone, then it might be just the SIP client for you..."
"Counterpath released an iPhone version of its Bria softphone at the beginning of the summer. The company promised not long after that another version for the Android market would not be far behind, and now—5 months later—it’s finally here...Like other Counterpath solutions, the Android Bria is an “Enterprise-Grade” VoIP solution..."
"There’s lots of buzz about SIPDroid, a “SIP client for Android” which is under GNU General Public License v3. The project page says SIPDroid “Adds native SIP/VoIP to Android's dialer/contacts. Make and receive calls over Wifi, 3G, and EDGE with perfect voice quality and lowest delay”. AWESOME! Open Source, Native SIP, Wifi, 3G, Perfect Voice Quality! Sounds good, right?..."
