It works. But may not be the best out there

There are better SIP/VOIP iPhone apps out there: Acrobits Softphone is my recommendation.

This app works. The audio is OK.

But it has an ugly user interface, and confusing and un-helpful settings. It only supports a single account.

While capable, there just isnt anything compelling about this inelegant app. Pay the $3 more for a better one and be happy.

I have no relationship to ANY app company except being a customer, by the way.
