*** Dropped iPad support *** Works well with Asterisk / PBX in a Flash

Clearly abandonware - very unfortunate.
How about an iPad formatted, universal version, upgrade?
Upgraded to 5 stars for g.729 support, and a slew of additional, excellent enhancements - not to mention the developer keeps improving and supporting an excellent VoIP client. I wish I could give him more $$$ ;-)
Upgraded to 4 Stars for supporting calling straight over 3G. Woohoo!
I run my own PBX in a Flash home and office PBX, and have been looking for an appropriate client on iPhone. This does the job, and it does it very well.

Some suggestions for enhancements that would catapult this well into 5 stars territory:

- support for the G.729 codec for even better quality. Yes, G.729 costs money to license - make it an in-app purchase. I would gladly pay an additional $5 or so for that feature.

- allow customizing the ringtones

- add custom quick-buttons for VM, for example.

- aesthetic changes of the look and feel to bring it more in line with the native look of an iPhone phone app, than some avant garde retro design experiment (allow selection of different skins, to appease avant garde retro afficionados). Maybe make skins an in-app purchase. ;-)

Do these, and a shining 5 stars, and more money, will be yours ;-)

Definitely on of the better SoftPhonee

I’ve tried almost every Softphone in the IOS ecosystem. While some have slightly better GUI’s than others, few actually have working reliable push features to notify you when your phone is sleeping or locked. This is one of them

I do see regular updates come thru, so development and patching is still happening, which is nice to see. I could see the devs improving the gui a little, and allow ringtone uploads, but overall, this Softphone mostly fits my needs and works well
