If using a SIP account, disabling STUN and / or Rport (or enabling it, depending on its current state) could help.

Please open settings -> Preferences;
click on Accounts;
select your account from the list on the left;
click on Advanced;
enable or disable STUN;
save the changes and try to recreate the issue.
