I've been happily using this for years. I had to rebuild my phone and it seems I need to install the new version which is limited to one account. So I paid the extra 6.99 for the new features. I don't really like the new interface or look. And it doesn't work when I use VPN on 3/4g. On wifi it's fine but on 3g I get dns lookup fail and registration fails. The older version is the same. I have decided to stay VPN connected all the time. So for me it's back to using csipsimple.
My incoming calls never ring and the call quality is garbage. It's delayed and gargled (even if I'm connected to wifi). The only reason I have it is because it connects to my yealink phone for work. It tells me when I miss calls and then I just call them back from my phone without the app.
Chris Hodgkins
This looks like the Beta Version not a minor update as suggested in "What's New" notes. It doesn't want to stay connected to the SIP account, and exits when my phone is in standby for extended periods. Is there a way to revert to the stable release?
Ron Kat
Dialing **620 to other extension will get error 404. It cannot be a server problem as it works from a phone. You are NOT replying to support mail and that is VERY inefficient!
As you can see from recent reviews, the new beta(?) version has been pushed to users causing many problems to some. For me, the voice no longer works half the time, calls are mute on both ends. I need to restart the phone or app for it to work, temporarily at least. Also the network quality seems to score lower although i have the exact same connection as before. It is clearly no longer a usable solution for me. Up until the 2.x version update came along, this was a great app.
Cesar Lopez
The last update doesn't work, the apps frozen and lost a lot of calls. The phone still ringing but the interface to answer not appear. Very bat update!!!

The dns lookup is a bug in android that we are trying to work around.
The new interface is the same as the native dialer. Just takes some getting used to. My incoming calls never ring and the call quality is garbage. It's delayed and gargled (even if I'm connected to wifi). The only reason I have it is because it connects to my yealink phone for work.

Can you contact us on support@zoiper.com and ask to test the samsung specific beta ? This looks like the Beta Version not a minor update as suggested in "What's New" notes. It doesn't want to stay connected to the SIP account, and exits when my phone is in standby for extended periods. Is there a way to revert to the stable release?

Check the number rewriting in Zoiper as it might eat the *. We do reply to support emails but cannot help everybody as we have millions of mostly free users.

Securax LTD. 24 December 2017
The only thing that should have changed is the gui. Keep in mind that those are reviews from 100k users.
Can you contact us on support@zoiper.com about the audio ? Í suspect it is due to wrong settings for rport and stun. The library is 99,9% identical to version 1.x so unless we messed up the settings there should be no difference. The last update doesn't work, the apps frozen and lost a lot of calls. The phone still ringing but the interface to answer not appear. Very bat update!!!
Securax LTD. 29 December 2017
Can you contact us on support@zoiper.com ? We have not received this complaint before. Securax LTD. 31 December 2017
We have identified one problem and are working on a fix. After upgrade can't hear other side when dial. How to fix it? Old version was working all right.
Securax LTD. 22 December 2017
Please check the settings for rport and stun, maybe the setting was lost. https://www.zoiper.com/en/support/home/article/14/Missing_or_one_way_audio#android After new update can't register "Registration failed (request timeout (408))
Securax LTD. 3 January 2018
We were able to reproduce the issue on one of our phones, we are sorry for the inconvenience and hope to have a fix soon. Securax LTD. 24 December 2017
What is the error message get when trying to make a call ? Old version much better and stable, how to go back to the old version?
Securax LTD. 21 December 2017
Scroll down the comments to find the APK File. The new version is more stable than the old one, can you explain what is the issue you are experiencing ? Nice interface. Easy to use and voice quality is superb.
Google Just updated to 2.2.29 the Beta version. Since the update none of my Sip accounts work. F. . K What happened? How to revert back to 1.53 version?
Securax LTD. 18 December 2017
Hello, SIP accounts registration process should be the same with the new version. Please contact us on android at zoiper dot com with information about the errors you see. Good app overall, but come on guys, the latest update where you changed the default to a screaming orange color, and force users to buy the pro version to change this is just plain cheeky. Currently searching for options to change to
Securax LTD. 19 December 2017
There is a second color scheme for free.
Sorry, we cannot give everything for free, we need to pay the bills somehow. We make the most popular android app for voip but the income is not sufficient to pay for the development, it is heavily subsidized by our other projects. The only other option is to stop making a free version. The recent update is buggy speaker is on bydefault and lot of disturbance 8n line.
Recent update keeps crashing. Unable to make a single call since last update.
Securax LTD. 8 December 2017
Hey there, if you are currently running 2.2.6(check Zoiper About menu), please remove it and install again to get 1.53. Incoming calls inconsistently make it to my phone and always start with speakers enabled.
Great stuff. Using asterisk on arch for simple sip communication and registrattion. Unlike the other sip apps this doesn't crash nor does it feel heavy. * had to lower rating because there is no landscape: I use a tablet. Bluetooth integration could be better. when using app in the background it is not easy to switch back to the call, like for hanging up. Being free and simple it is still the best one. // response to developers : on going call does not appear in my notifications
Securax LTD. 20 November 2017
Landscape support is coming, you can already get it if you apply for the beta.
Switching back to the call is like with the native dialer, slide down from the notifications menu to get back.
I will ask the development team to investigate this more, can your tablet make GSM calls or it does not have calling functionality ? Nice app very reliable. However hands free is broken when voice dialing. Must select network on phone to use to place call even when there is only one network available. Would change rating to five if there were a way to be able to make a completely hands free call when on blue tooth in my vehicle Update to response from developer. The phone prompts to select either VoIP network or cell network even if VoIP network is not available when making an outbound call. This only becomes an issue when hands free on Bluetooth. It is not actually a Bluetooth issue but a dialer issue.
Securax LTD. 30 October 2017
Better bluetooth is coming, what do you mean with the only 1 network available ? Only 1 sip account registered you mean ? Works as it should. Sounds logical, but when you have tried other apps, you know why I'm so happy about that! WARNING: The "minor fixes" in the update will prevent you to add more than one account. Reverted to old version and removed 3 stars of the rating for this behavior!
Securax LTD. 24 December 2017
Sorry we need to pay the bills somehow. The android project is still heavily subsidized by our other projects. I have been using this app for a couple of months and have generally had a good experience until a few days ago. I am unable to make any outgoing calls and keep receiving a 'Timeout 408' message after trying to dial out. It is not my internet connection or my firewall as I am still able to dial out from my computer which is connected to the same wifi but the sound quality is awful. I am still receiving incoming calls. Please advise how I could fix this as it is interfering with my work and causing me to lose money.
Securax LTD. 18 September 2017
If you suddenly have an issue but the app hasn't changed, the issue wont be with the app. Try reinstalling but i doubt that will be the problem. Search on our FAQ on the website for common issues with voice quality. The app is so far so good but it is missing a lot of functionalities compared with media5. I like to make 2 feature requests and I will rate it 5 stars if the features are available either in future updates or in the newer version currently in beta. 1. Implement a support for internal speaker gain. The current gain in the setting only applies to the loud speaker. Make a separate setting for internal speaker gain. 2. Implement an in-built SIP trace or if not, make it possible to send sip trace to syslog server. This app will be worth my 10 stars if these two features are implemented. I am currently looking for alternatives to media5 because it is going yo reach an end-of-life by August 2018 and I found zoiper as a great replacement. These are the two reasons I still use media5 instead of this great app. If these two features are implemented, I will stop using media5 right away and buy the gold subscription, including all the premium features. I will be looking forward to your input on this. Thanks in advance.
Securax LTD. 18 September 2017
first one is sent to the developers. The built in sip trace we will probably not make. It's easier to sniff it the network. This app was terrible. I paid for the gold version. I tested it with my system at work and was constantly cut off. When I put clients on hold the line would just go dead. It would not even play our hold music or go to voice mail. Transfers did not work at all and the connection was awful when it did work. I work for an IT company and my team of phone and computer technicians were unable to get this app to work at a usable consistancy. I would not recommend paying for this app. Despite the desktop version working well. How do I arrange a refund?
Securax LTD. 19 July 2017
You can contact our support team. When you put people on hold and the line goes dead is a problem with your server configuration though, not the client. Transfers not working is also a server configuration issue. Connection quality depends on your network quality (and can be verified during a call). Not serious! I bought gold licence including g729. The became "lite" but worst. Now it is "beta" and I cant no longer log in with my usual SIP provider! What a non serious customer care!
Securax LTD. 25 July 2017
The beta is because you asked to go to the beta version. You can still log in with your voip provider. What is the error you receive ? v1.53 Beautiful BUT will not make calls on my VoIP-SIP service (which can make calls on CSipSimple) and cannot unsync native phone app integration or trun off "always on" (CSipSimple can). I will use this app if I can make calls in future releases, disable "always on" in settings, and choose to not integrate native phone call history.
Securax LTD. 18 September 2017
I think its possible in version 2.0 that is currently being sent to customers, you should get the upgrade in a few days. Using this with VOIP.ms service. Cut your cord but keep your home phone number and always be able to answer your "home" phone even when you are away. With Zoiper I don't even bother making outbound calls with my cellphone but instead just use the data or wifi to place calls.
Huge problems with using the keypad once I am in a call, as in activating a credit card. Call works fine, 15 tries to enter the CC number fail. This is happening with perfect reception of the voice prompts. It happens both over WiFi and over cell data. Even worse, installing and using the Mac version of Zoiper and calling the same number over the same WiFi network worked the first time.
Securax LTD. 5 September 2017
please ask your provider what to use. Sip info or rfc2833, it depends on the server setting. If it does not work reliably, ask your operator for assistance, zoiper is definitely doing it properly :) If csipsimple is not simple enough for you, Zoiper delivers! Advanced features are paid but all the basics are free. Stable, fast and functional. Will buy paid version when Bluetooth is 100% supported.
New version simply doesn't work at all. Fresh install and it crashes in a loop. When I'm finally able to use it, I can see it register on the PBX but the line never rings. I have a second device with an older version and no such problem. It also drops calls but keeps the line active, so you think the person is just ignoring you while in fact they think you hung up. Uninstalling does not remove preferences or configs, so when you reinstall you get the same problems. And if you deactivate an account, expect it to reactivate on its own randomly for no reason.
Securax LTD. 30 October 2017
uninstall removes all settings (probably you have them backed up ?) I cannot find a support ticket from you for 2017. The reactivation is because you have selected register on startup for the account. Can't help you for the other issues without more info. Still having issues after update. Has not fixed samsung 7.0 Caller still unable to hear me, even though I can hear them fine.
Securax LTD. 19 July 2017
Can you please contact us on support@zoiper.com ? This issue should have been fixed already Its Ok, I needed to update my review for this app. My original complaint was that the audio sound to the caller was unusable when your on bluetooth, they could barely hear me. After messing with the setting I found the the audio driver in the settings was default to "openSL ES" and that don't work correctly on some android phones. If you set it to "External Java Driver" it will clear up the audio to the callers side. they will hear you much better when your on your bluetooth. so I'm changing my 3 stars to 4 stars.
I been using this app 4 years now and it's super awesome. Has neva let me down so far.
Works very well with my voip.ms account, but does not vibrate my Bluetooth headset (LG HBS 810) when receiving calls. Lots of missed calls as a result. I tried to switch back to the native Android SIP client on my Samsung Galaxy S6 for this reason (which does vibrate my headset), but reliability is much worse than Zoiper. I'm going back to Zoiper for now, but hope they can implement / fix Bluetooth vibration. I'd pay for that feature. (Update 2017.07.18) I have updated to Beta as suggested, but the issue still persist. In fact, there is another issue with answer calls using the headset. I've left a description of the problem on the Beta app's review, but so far there is no response.
Securax LTD. 25 July 2017
Please upgrade to the beta (the link is in the app description). It has much better bluetooth support.
I could not find a review from you in the beta app reviews. Can you please resend it on support@zoiper.com ? I don't get a ring on incoming calls. Only vibrate. Help!
Great app, i have asterisk server as PBX and good work. If you are have troblem i think your connection is poor and mistake configuration.
Great app but disconnects from network too often. Voice qual is great. Interface could be better (looking) but not at all bad or hard to use.
I have a problem that while incoming call i can listen the other person cant listen to me pls advise. Outgoing its working but onky incoming the other side they cant listen to me
Securax LTD. 20 November 2017
We think we have a fix for this problem, can you contact us on support@zoiper.com and ask to get the build with the new audio driver for s7 s8 ? thanks! I own a small msp and deploy VoIP phones to my clients every day. This is a great app for connecting those clients through sip to their current phone system for when they are out of the office. There are many other sip soft phone apps out there that cost money but this has the most features for being free.
