*** 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 ;-)
They fixed the really annoying camera issue! That was my only complaint. Great app!
Developer Response ,
I am sorry you are having issues with the app. We're not aware about any problems related to camera. Our app doesn't touch camera unless there is an active video call, it's a telephony app after all. Please contact us at firstname.lastname@example.org and we can troubleshoot.
As for the battery consumption, with iOS 12 made things really a bit worse when using "standard" incoming call mode. Fortunately, you can use the default "push" mode, which does not consume any extra battery power and still lets you receive your incoming calls.
Edit: actually, we have found the camera issue! It's quite strange, voice calls made through our app somehow interfere with autofocus in system Camera app. The next update will contain a workaround for this. Thank you for reporting it and we're sorry for the inconvenience.
After purchasing this app many months ago I’ve finally tried it with the FlyNumber wwPBX. Believe I’ve set it up with proper account info, yet every couple days SoftPhone gives me a pop up message that my FlyNumber account has expired on the push server. Huh. I know my account hasn’t expired on FlyNumber, but who is running the server mentioned? Where do I get help on this? Giving SoftPhone the shadow of doubt, I’ve rated it 3 stars even though it hasn’t yet served for a single phone call.

please contact us at email@example.com , we can't discuss specific cases on the review forum. The message you are getting indicates some problem with push notifications, I am sure we'll figure it out.
