This problem could have a few different possible reasons.
It could be that the network you are (or the other side in the Philippines) connected to is blocking Viber's traffic.
1. First, please try uninstalling and reinstalling Viber when connected to different a few WiFi networks. Does it work now?
2. Also, please make sure the following ports are enabled on your routers or firewalls:
TCP: 5242 + 4244
UDP: 5243 + 9785
(if you are not sure how to enable ports, contact your router manufacturer)
Also, it could be that your Viber contact list needs to be resynchronized. Here is a quick guide for a few methods to reboot the synchronization:

We would appreciate if you could let us know if it worked or not

Unfortunately for now there is still no way to separate Viber calls from regular calls in the Android call log. In the future, we are planning to add the option of separating them. We apologize for any temporary inconvenience caused
