instead, youll see a 'Call' button..

but when you click on the 'Call' button (on a user that doesnt use Google Talk)
youll get this message:
<< You cannot call because ~the users name~ is using chat in Gmail or another chat program other than Google Talk. >>

anyone know why Google removed the VoiceMail button?

i dont have it david .... i still get the same send voicemail button for offline buddies...
b.t.w why does it have send file button for offline friend ?

dunno...
but let me check it..

the button also appears when a user who uses Gmail Talk. but when i hit the button it says the following:
<< You cannot send files because ~the users name~ is using chat in Gmail or is using another chat program. >>

<< the button also appears when a user who uses Gmail Talk >>
correction:
the button also appears when a user who uses Gmail Talk is online :)

Google has changed its location..

maybe Google is "promoting" the 'Call' button, cause we will able to call to Gmail Talk users?! hmm might be... (but im not counting on it)

"Call" when the user has a mic and is online.

"Voicemail" when the user is offline.

<< "Call" when the user has a mic and is online. >>
thats half true..
i called my uncle using Google Talk.. but i was the only one who could talk.. he was at work at the time, so he didnt have a mic, but he did have speakers..so he could hear me

<< "Voicemail" when the user is offline. >>
thats half true also..
you can send voicemails to person whos online.. (who uses Google Talk)

u can always right click a contact and see if it's disabled or enabled to voicemail him..
