[asterisk-users] softphone instead of desktop phones

[Thomas]

Hello,
Iam lookong for an Softphone for iPhor oder Android smartphone using togehter 
with an headset.
I tried Zoiper and CSipSimple but quality was bad compared to an desktop SIP 
phone.

Is there an better softphone?

Or are there softphone solutions for PC desktop MAC or Android with an 
headset?
I want to save cost for desktop phones.

thanks Thomas
