  • This was posted at the perfect time. Thank you for this great post. G.722 on mac’s, windows, tigers, and bears. Oh my!

  • Cory Andrews

    Fred were you looking for something with which to participate on Friday’s VoIP User Conference on HDVoice?

  • Yes sir.

  • josue_xavier

    Well, This article is very intersant, I have looked it…but ever i found X-Lite, SJLabs…and others i know not about any softphons wich as: WXCommunicator, Mirial Softphone, etc…I prefered the FaramPhone is very atractive im going to probe with my Central Asterisk…

    Thanks for this…

  • Shawn

    Do any of these support distinctive ring features?

  • Emil

    Another (Asterisk-compatible) GPL softphone is Kiax (kiax.org) – Not a SIP softphone, but an IAX one, runs on Windows, Linux and Mac (intel x86).

  • Luc

    Interesting article. Thank you for sharing this information.

    As softphone I always use X-Lite and Voixphone.

  • Paul

    Some notes on G.722 capable softphones: It seems that QuteCom will work via asterisk 1.4 between softphone clients, but though the audio range sounds great, there are noticeable stutters during a wideband call.

    Some softphones don’t seem to be able to make direct calls between themselves and Polycom Wideband phones. Audio spoken into the softphone will not come out the Polycom. I’ve heard it works fine in a conference bridge.

    Also, don’t bother buying Bria or Eyebeam direct from counterpath if you want g722 codec. They only include it on versions sold to OEM resellers. In particular, look at the one from ZipDX, who offer wideband conferencing services.

  • Paul

    Also, I heard there is no g722 for the Mac version of Eyebeam OEM.

  • steve

    One very good open source softphones are missing :

    – ippi messenger based on the great SIP communicator.


  • Luke

    Thanks for the list of softphones. My X-Lite suddenly stopped working and caused my computer to reboot every time I tried to make a call. For me, finding another free softphone is urgent as I use this as my primary home phone. I installed ExpressTalk and it seems to be working….for now.

  • Brian

    I have an AdTran NetVanta, which is SIP compliant and I have their version of SoftPhone. Any idea which of these will work with my AdTran device?

  • Cory, did you ever look at my company’s http://www.mozillavoip.com ?



  • Luke

    Can anyone recommend a WIFI SIP Phone for around $100?



  • Liss

    Sorry, but where is g.729 in QuteCom?
    Maybe another softphone have it free?

  • Liss

    Sorry, but where is g.729 in QuteCom?
    Maybe another softphone has it free?

  • voip phone guy

    Thanks for the huge list. I didn’t think there that many options.


  • Hi
    I am the deveoper of the MizuPhone sip client listed above ( http://www.mizu-softphone.com ). I see many comments regarding g722 and just want to share my experience with that. To be short: speex is much better and supports ultra-wideband too. It has lower bandwidth requirments and it is open source (mizuphone supports g722 too, but the ultrawideband speex quality is better than skype )

  • You can also add Mercuro IMS Client (http://www.mercuro.net). Mercuro is an IMS client that could be used as SIP client. Is compliant with IETF/OMA/3GPP/GSMA specs. For capabilities you have: Voice, Video, chatting (MSRP, SIMPLE with both pager and session mode), XCAP contact storage, MSRP File transfer, …

  • Jim

    @Liss: check out the qutecom wiki page which details the codec support.


    It mentions G 729 there, so I’m guessing its OK. I’ve been looking for a softphone for Linux which supports G 729 and the choices are slim.

  • M.L.

    Mirial Softphone is not free.

  • Hai

    Have a look at PhonerLite (http://www.phonerlite.de). It supports G.722 and Speex-Wideband!

  • You guys can try our softphone

  • One more to take a look at is a JavaFX softphone for Google Talk at VoiceClearly (http://www.voiceclearly.com/googleTalkVoiceClearly.jsp).

  • Alexei

    Take a look at Telephone–very simple and lightweight softphone for Mac. http://code.google.com/p/telephone/

  • Jim

    It might be useful to add which phones can be used as USB stick portable apps.

    The only two I have located so far

    Any others?

    Why bother ? If you have Wireless Broadband on a stick…something like a HUAWEI E160 they come with a micro SD card slot. Putting your softphone on it makes sense you can then use it with any Notebook etc

  • I’ve installed the first Internet phone and credit I want to install


  • Valistar

    Nice article,
    Do you know if an API exists to develop plugin for some open source softphone on linux? I mean, without touching to the source code?
    Thank you,
    Best regards

  • Catherine

    have a customer interested in using softphones for their law office. Anyone have a recommendation of one over another?


  • Garrett Smith


    You can’t go wrong with CounterPath’s X-Lite.

  • Vitali Fomine

    OfficeSIP Messenger is one more free Instant Messenger and softphone (communicator?!)

  • Kevin

  • JP

    Is there a SIP phone that supports AMR-WB[G722.2] codec? The Wengphone rebranded as Dooxsoft claims that it support AMR-WB and the trial version doesn’t.

    Thanks in advance.

  • jacob

  • You can also try our free version of CCI-Phone. This is a SIP softphone that supports in commercial mode g729,g722,g711U/A

    If you want to try let me know.

  • Leo

    Do any of these soft phones support call transfer (attended transfer or blind transfer) ?

    Haven’t been able to find one that does.

  • What about Blink (http://icanblink.com/)?

  • RafRaf

    How can I find out which of these phones support multiple SIP account registration? I want the phone to register simultaneously with 2 independent SIP accounts.

    Thanks for your help

  • Mark

    I think the open source ‘SIP Communicator’ is missing:


    I like them.

  • Hi I’m a developer at

    Just wanted to thank you for these nice collection of softphones.
    Do you have any free applications for H.248 (MEGACO) ?


  • Scott Berry

    Well one of the things that is hard is I am totally blind as in can’t see and I know a lot of these phones are really difficult to use for blind peoploe.

  • aman

    Is there any sip phone which has proxy settings in connection and username and password for proxy authentication same like in Gtalk connection section.

    I am using xlite and in office i connect to internet by proxy server

  • Is there a soft-phone that allows free 3 way calling ?

  • Jeff Greene

    Are any of these softphones compatible with Google Voice?

  • Jeff,

    You can use Express Talk as listed above with some configuration. Here’s an answer from the Google Voice Help Forum:

    “You don’t configure the Express Talk softphone for Google Voice, you configure for a SIP service like Sipgate or Gizmo.

    For sipgate (sipgate.com) or gizmo (gizmo5.com), you will need to sign up first. You will then need your server or sip proxy address. You will also need your SIP number and password.

    You will then pull down the File window in Express Talk and choose Options. In Options, you will click on the tab called Lines. There you will input your Name, Server/SIP proxy, SIP number and password. After you are done, click OK and the Express Talk should work.

    For Sipgate, you will find that Server/SIP proxy is sipgate.com / Gizmo is proxy01.sipphone.com

    For Sipgate, the SIP number is something like this (each person is different): 9495541e0 Gizmo is something like this: 17474634XXX

    For Sipgate’s password, you will have to use theirs. You can find this in your settings, when you click on Phone of…, it will have a pull down menu and you choose SIP credentials. For Gizmo, I believe the password is the one you chose with the account.”

  • Vadim

    Can someone tell me, if any of this softphones support auto-answer? Zoiper does, but only in Biz (non-free) edition.

  • Vadim

    DIAX supports auto-answer, but it works with IAX only, not SIP (so, there is an error in its description on this page)

  • Roy

    Any free option for web-phone? (clic-to-call buttons at least)?


  • MicroSIP: lightweight SIP softphone based on PJSIP stack for Windows OS written in C++. SIMPLE IM and Presense. Download here http://microsip.org.ua/downloads

  • Guillaume

  • Need a soft phone which sends Record Route Header..

  • Vinh Le

    thanks !

  • hi,
    popular messenger Nimbuzz also has a VOIP features, so you can add SIP account and call easily. Check at http://www.nimbuzz.com

  • Comentator

    “QuteCom supports a range of VoIP codecs including G.729, G.711, iLBC, G.722 (wideband) and Speex. H.263 for video is also supported.”

    This peace of crap does not support g729 codec or this codec might be stealth so I can not see it in configuration which I doubt as I tried to call with server which support g729 and get error.

  • New SoftPhone for Call Center, goto: http:\www.aplitel.com

  • sflphone is quite feature rich and cross platform. I use sflphone and linphone for my linux platform.

    But it’s not working on Windows8.
    I got an error when I choose custom install and after the Setup it crashed with an application error.

    Hope you will fix this!

  • Alex

    Can anyone please advise if any of these softphones allows to change output ‘cli’ or sometimes reffered to as ‘output CID’

  • Stone Conservation Supplies

    I saw another comment about multiple sip accounts, has anybody got any idea which clients support this? I understand the 3CX Windows client supports this but unfortunately stopped working when I upgraded my laptop to windows 8…

  • Russell

    Is there a softphone out there that supports ALL the functionality of the Ring Central voip service and Plantronics Voyager Legend-UC Bluetooth (B-235) headset (free or otherwise)? I am using the Ring Central (free) call controller and the Bria 3 softphones and neither seem to support ALL the functions?

  • I used Linphone quite a while, it was stable, lightweight, but i was a bit frustrated with the UI and the contacts list, now I am looking for sth better. Thanx for your list so 🙂
