I just saw your call in the logs! It will work in Serbia, but I need to do some additional work on the backend to enable certain countries that are typically high cost to call. I had already done this, but apparently it wasn't complete. For now, I've reset your trial call limit and it should work for you.
Whoa, it works! I was surprised to actually see a service with such a wide coverage. I've made an account and verified it, and all seems to work smoothly. The only thing is that I can't find any info on how much the messages or calls cost. Maybe I'm missing something obvious. I'll also be sure to recommend you to people I know are having this specific difficulty of poor call quality with Skype or Viber. That's a grea…
Of course many countries are not nearly so much. I also do plan to add voip calling within the app. This would allow you to skip the high cost of crossing Serbian boundaries when you're near a decent internet connection, but give you flexibility to make calls directly over the PSTN when needed.
