No more transfer?
Great product, but since the latest updated the transfer button and attended transfer buttons are no longer available. Is this feature still available?

Superb SIP softphone; provisioning could use improvement
In a world where software design and development prowess normally does not accompany SIP softphones, this app stands out as a nicely polished utility with great functionality and customizability. Dialing / call interfaces look great; the app pulls well from your contact list; allows you to switch between SIP connections efficiently, etc. All of that said, I had some trouble figuring out provisioning, because certain parts of an XML account node would not do anything; I figured out that when I delete an account entirely and re-provisioned, it would work, but when I had already manually configured some things, provisioning would silently fail to overwrite some things (like title or SIP credentials), but not others (like voicemail number), etc. That was a bit of a struggle, because I shouldn’t have to worry about the state of an account when I try to provision.

Excellent app with a killer feature
This is a great app for family or enterprise use. Great voice quality, flexible options, nice integration with iPhone (and iPad), lovely user interface. And: After some plowing through Acrobits’ wiki and scratching my head a little, I found it supports external provisioning. That’s wonderful: you can set up simple .xml provisioning profiles on a web server (or even in Dropbox’s public web folder) and give your users a click-link that, when clicked on their iDevice, will automatically set this application up. I’ve encouraged Acrobits to improve the description of how to do this, but if I figured it out you probably can too. Really great app, and well worth the small amount of money it costs… especially considering the massive savings VoIP brings! UPDATE: after several years I remain delighted with this app. Call quality, ease of use, iPhone-worthy design... first class stuff.
