Softphone for Iphone recommendation


I am not an IPHONE user, and one of my customers needs to connect to my asterisk via an IPHONE.

Which softphone could you recommend ? free preferably !



I have good experience with Zoiper.

the issue i am finding with “softphones” on mobile devices is that if the app isn’t running - no calls come trough.

On Blackberry (and i beleive the iPhone does the same) - Skype app doesn’t have to be “running” to receive calls -

I would really like to know if there is a soft phone liek that for cross platforms.

Skype will have to be running to receive calls, it just won’t be generating a user interface.

Linphone and 3cx are good and both will as does skype run in the backcround
