The developer has spent a lot of effort with making unique interface (= applicaiton overdesign). It doesn't necessarily mean the unique interface is an easy to use one. It could have been better left alone (keep it simple).

However I deleted the app because I wasn't able to get consistent connectivity with Callcentric. Most of the times it can establish connection to Callcentric but sometimes it can't.

I haven't tried other SIP providers so I won't rate this software but right now I can't give it more than 3 stars at max.

Appendix iSoftPhone, displays communicate at a distance of a whole new level. With it, users will not only make calls via IP-telephony, but also save the address book in OS X phone numbers, and even data on all recipients. The latter feature is particularly useful if iSoftPhone used by companies to communicate with customers. In this case, all the details of cooperation can be checked in the computer.

If a person is already working with voice over IP-based, it is only necessary to configure it to work with iSoftPhone.

To make calls, you only need an Internet connection. Calls from one computer to another - for free and communicate with subscribers of fixed and mobile payment is still required. (However, these calls can be made free of charge, if such record numbers as users of IP-telephony.)

ISoftPhone application also features an integrated Bonjour technology from Apple. It identifies other iSoftPhone users in the LAN, with whom you can communicate without the mediation communications provider IP-based.

Client iSoftPhone adds IP-based Unified Communications Cisco Unified Communications, contributing to a more productive business communication with each other and with clients.

I want to emphasize that the program iSoftPhone is the best of its kind!

Thanks to the developers for a worthy product!

Best Regards Vitaly!

This is a snap to set up and works great with voip.ms on 10.6 where X-Lite was crackling like mad. And not as clunky. I like how the interface is relatively compact (ahem, Skype?). It would be awesome to be able to shrink it down even more in the "floating" view. Loads of truly useful features. Couple more codecs would be a bonus.

Still not 64-bit...

Libertyforall1776, I've been defending you and your obsession with 64-bit architecture for almost a year now, and in the process I’ve drawn a lot of fire from all those obnoxiously arrogant 'IT-Guy' d1ckheads whose responses to your multitude of posts crapping on every app that has updated without upgrading have exhibited way too much joy in smacking you down.

And so, I’d be thrilled if you'd do a little research on this issue, if only to disabuse yourself of the notion that moving to a 64-bit architecture will dramatically benefit all or even most applications. In fact, 64-bit will only speed up certain types of computation, and even those are unlikely to gain much more than 20% or so. Of course, there are some that will benefit substantially — as long as your definition of 'substantial' is no more ambitious than 35%. But a lot of apps that can benefit a lot already have made the change, simply because sticking with 32-bit after 64-bit became the norm would’ve been tantamount to chucking money out the window (and into your competitor's window).

I realize I just laid on you basically the same turd as those flatbutts did repeatedly over the last year, with the only notable distinction being that I didn't throw it at your face angrily. But sometimes the only way to tell your friends from your enemies is to take note of the ones who aren't laughing while they piss on you.


Apple lays out the benefits of 64-bit apps, and NO it is NOT just about memory! Check it out. Besides, anyone can change a 64-bit app to run in 32-bit mode by doing a Get Info on the app and making the change! The option should be in the hands of the end-user.


Yes, once an app has been rewritten in 64-bits, it can easily be switched back to 32-bits in the Get Info dialog. But, 1) MOST APPS WON'T BENEFIT FROM 64-BITS AT ALL OR ANY MORE THAN 5-10%; and 2) REWRITING AN APP IN 64-BITS IS NO SIMPLE TASK, not by a long shot. It can take hundreds of expensive man hours and cost tens of thousands of dollars — and it will make next to NO DIFFERENCE for most apps, especially prior to the day when Apple upgrades all the other parts of the OS and its major frameworks to 64-bits!

Furthermore, no matter how many gigantic, boldfaced, neon colored warnings a developer posts on his app's ReadMe, in its MacUpdate.com post, or even within the app itself, to instruct users who don't have 64-bit CPUs to change that app back to 32-bits in the Get Info dialog, you know there will be hundreds and even thousands of unsavvy folks out there who won't figure that out or who will simply get angry at discovering that their Mac doesn't run in 64-bit mode, and I wouldn't want to be the developer of the app that illustrated that to them. For that reason alone, I don't fault makers of low-complexity app that won't benefit from 64-bits for not rewriting them until it's finally necessary because Apple releases a thoroughly 64-bit ONLY operating system that fully supports it.


It seems that many people aren't getting one point: Even if most single applications won't benefit from going 64bit, if ALL applications went 64bit you'd save a bunch of memory by not having to load the 32bit AND 64bit verions of all libraries into memory.

Really bad sound quality, so bad that most people complain and ask me to call back.

Also, I can't dial normal extensions, sometimes I can change a codec to PCMA or something like that on the list and then it helps but then it seems that this particular function has nothing to do with being able to dial extensions. I spent a half hour trying to call my medical clinic this morning.

Also the customer service bites. John Seehy seems to be the only English speaking guy because someone else mentions him in the comments.

What a waste of money! Too bad because its a nice design but it really doesnt work well. Who can have an SIP/VOIP phone that doesn't allow you to dial extensions????

I like this app (and even purchased a license) but it is not working as well (for me) as X-Lite beta. Once connected, bits and pieces for the conversation go missing or are delayed, and typing in e.g. a conference ID (DTMF codes) rarely results in the other end deducting the right digits from the tones. Not reliable enough for me...

MY VOIP provider included Counterpath's Eyebeam product. It was good, but then I found the iSoftPhone. I use it in the office, when I travel, in airports, hotels, everywhere. The integration with address book really sets it apart form the competition. It looks great and works even better.

There is one feature that I have requested. A key that will substitute for a # key. I do a lot conference calls that require everyone to login and that nearly always requires a #key. Other than that, this is the best product.

This new version rocks. I've tried the app in its early stages, but I was really disappointed. Since then the voice's quality has improved, as have the semplicity of use and the options. Plus, the price has dropped down. I've contacted the developer in order to ask for a cross-grade from eyeBeam (that's the commercial version of X-Lite, we have 7 licenses running) and he offered me a 25% discount, besides the normal "quantity" discount you can obtain on the site if you buy more than one copy of iSoftphone. I've also tried SJphone and Express Talk, and - as far as I can say - this is the one and only app developed with the Mac user in mind.

i purchased isoftphone almost a year ago.

to date john sheehy/ isoftphone is still unable to provide me the correct setting to use their application: it is by far the $35 best wasted!

DO NOT BUY IT: it is virtually impossible to find a working port!

Sorry, but this is BS. I use it since more than a year without any problems. And I had two different providers.

Its not their fault if your settings do not work. Try to check your firewall and router settings.

An no, I am not affiliated with the company.


I use iSoftPhone and it works nicely on my Mac.
If you want to use a Sip or Softphone sofware, then you often have to check or set your router and firewall settings (eg you might need to open some ports), so that it can work properly.
