I am getting many anonymous calls from numbers such as 3001 and 1002. how do I stop them?
Thanks
You may add these as contacts and block them.
Adding them as contacts is OK.How can I then block those contacts?
Actually you can't.
The "block" contact option will work only for the Zoiper P2P service. You would need to change the SIP port from 5060 to something else. E.g. 5095 from Zoiper -> Settings -> Preferences- >Advanced -> Network sub-tab.
Thanks. I thought the answer might be wrong because of other posts I had seen. Thanks for the info.PS I have no idea what "P2P service" means.
So, there is no way to stop those?
You can do so by changing the listening port as described above.
