What if my provider blocks VoIP?

In some countries mobile operators and internet providers block their client’s access to VoIP over SIP.

If this is the case, it is possible to connect via alternative ports.

Connection data:

  • Protocol: TCP
  • Port: 5065

For example in Zadarma app for Android follow the procedures below:

  • Click the Menu tab in the app;
  • click «Zadarma» (account details will be displayed);
  • Click the Menu tab again;
  • select Advanced;
  • In appeared settings select "Use TCP" and enter below: sip.zadarma.com: 5065
