1. Please help !! Update: all screens whether incoming or outgoing have blank screen/interface Please roll back to old versionIt always logs out and take more than 2 hours to log back inApp doesn't start on samsung android 12, keep crashing with error message "change registration time to 3600" but has no option available to make chargesMy phone and million other phones save the numbers with a space, your app doesn't strip it before passing it on to the sip server, is there a way to fix this - your dialplan only strips leading characters not spaces in the middle.
2. If the phone is not silent, Bluetooth will play the ring tone over whatever media you may be playing, there's just no incoming call notification on the car display.Works for the most part, but cannot use ilbc codec (best for reliability).. asterisk complains: "Huh? An ilbc frame that isn't multiple of 50 bytes long from RTP (38)" ... Pity App seemed okay...this app is too good to be true... it works great so far.
3. One thing that doesn't quite work is the incoming call notification is not passed to Bluetooth.
4. however, i do wish you could set different ringtones for inbound calls to the appRequires camera permissions to open up and makes the suspicious claim that the permissions are needed for the app to work.
5. There is of course zero reason to require camera permissions until the user initiates or receives a video call.
6. As is, the one-star user experience I had with the app was trying to open it, being prompted for superfluous permissions, being lied to as to why, and then uninstalling the app.I've been using this app for 2 years now.
7. Howver the last update says it fixes an issue of a blank screen when dialing, I never had this issue, but now when I installed the update I started to get this blank screen when calling voice mail.
8. It automatically answers a call even without clicking the answer button and you cannot hear it ring.
9. Still, the app is easy to setup and configure, intuitive layout, compatable with various VOIP providers, customizable, and loaded with features.
10. TLS doesn't work if you are connecting to an external server.
11. UDP behind symmetric NAT doesn't work.
