Well, more than one year after Google acquired Gizmo5 it seems that they kill the desktop application (like their own GoogleTalk client in Windows). The last Gizmo5 for mac crashes consistently on OSX 10.5 and 10.6, the possibility to place calls using another SIP provider disappeared, the GUI is getting ugly…
Only plus point is the xmpp compatibility and the use of SIP protocol.

Oh no: Big G assimilated Gizmo !
Let's see if Big G is going to respect privacy (and data privacy)...

Wow, I thought Gizmo for Mac was dead, it's so crashy-bad. If they can make this app work again, it'd be awesome.

I personally use it for instant messaging. I use it for instant messaging because it does AIM, Yahoo, and some others. Yahoo Messenger for mac doesn't have photo sharing, so there's no other reason to use something else besides Adium. I've never had a problem using Gizmo for voice chat, though Skype usually works a little better in sound quality.

F***ers wiped out my account balance and now don't recognize my registered email address, though they keep sending me spam there. Grrr...

Gizmo5 (which is actually version 4.0... duh!) fails to launch after updating to 10.5.5.

"just needs a little more put into it", such as?

What you have posted is not a review, it is a comment and you should not have used the star-ratings. When a person clicks on the "Write review" link here at MU, the resulting window states: "Please backup your claims with reasons". All you posted was a vague opinion. Not helpful.

Well the rating is bad, bcs i would recommend anyone to stik with the old 3.1.2 version, even so it has no video function, stability and most of all the ACF function works.
To explain:
ACF = All CAlls Free, which means the buddies on your list may become ACF members, and then you are able to call landline/or even mobile phone of those for free.
The new version seems to get nuts on this feature, it marks almost everyone as active ACF (curiously some are marked inanctive ACF (so i can use this plan in the old version).
Which means in fact :
The new version shows peoples number like you are able to call for free, but EVERY CALL you do is charged! Even the ones previously used to be free!
This is a big step backwards most annoyingly cannot rely anymore on the ACF Status.
Even so it might make your acount settings confused!
So if you like the ACF plan of Gizmo you better do not touch this Version !
PRO : Well it has no video and like always Computer to Computer is free anyway
CONTRA : Using it for mobile / landline you never know , if you are charged or not (well most of the times you are charged)

I needed an extra number for incoming calls and the occasional outgoing call and Gizmo works perfectly with my Macs. I've had it with the high costs of traditional, old tech phone companies.

The Gizmo interface could be a little sleeker and more compact but it's not a problem.

I wasn't keen on becoming a supernode for Skype, dealing with Euros or payment issues (I had them).

I waited forever for Google's GrandCentral and for iChat to be something more than AIM.

Overall, a fine program.

It does have that Mac-ish feel, but there is definitely some clutter.
