Recommended SIP client aka Soft Phone?

[ericmachine]

Hi everyone,

I am looking for a good SIP client aka Soft Phone that works well on these platform:-

a. mac os x (lion)
b. windows 7
c. iphone 4/4s & ipad2
d. android (sandwich/ice cream)
e. blackberry (if possible?)
f. windows phone (optional)

Workforce around 10 people.

The closest I could find is

Bria3 which is able to support most problem

But I am not sure whether Bria3 is good or not? I plan to purchase if needed to.

I am open to use mixtures, say product A for mac os x lion and product B on iphone, as long it is a good product and doesn't crash or cause problem.

I google around and found these:-

zoiper classic
zoiper communicator
is-phone desktop
is-phone mobile
qutecom windows/mac only
acrobits iOS/android
media5-fon iOS
fring

My main concern with these sip clients:-

a) if i use any of the above for iphone and while I am on the line via the SIP calls, then I receive an incoming calls from other local number. Will I get disconnected from the SIP calls?

b) Good noise cancelling

d) which one can link up with elastix conference, IM and address book too?

Any recommended advices for me? Thanks.

You also have 3CX phone and X-lite.
I like 3CX, but I think it`s not available for MAC.

Claudio
