Block or redirect anonymous and unwanted calls
Block or specifically redirect anonymous and unwanted calls in sipgate – set this up in the account.
With your account, you can control how unwanted callers are handled — either block them or redirect them directly to voicemail. This applies both to specific phone numbers you want to block and to anonymous calls or marketing calls.
Important: For blocking to work, voicemail must be booked and activated.
Anonymous calls
Open the User detail page and click on Edit routing. There you will find the toggle Block anonymous calls.
Block: Callers hear a message saying that you are currently unavailable. &#xNAN;Note: Existing call forwards will still apply.
Redirect: The call is routed directly to your voicemail, where callers can leave a message.
Confirm with Save and then click on Finish editing, so that the changes are applied.
Note: These settings are not available in this form on sipgate neo.
Anonymous faxes
For analog fax machines, there is the toggle Reject anonymous faxes:
Block: The calling fax receives an unavailable message and tries to send again three times. Important: First deactivate all call forwards.
Redirect: The fax ends up in voicemail. There you will receive three messages with fax tones.
Note: These settings are not available in this form on sipgate neo.
Block list for unwanted calls
If you want to block specific phone numbers (e.g. marketing calls), use the block list. Go to My Telephony → settings → Block list and click on Add phone number.
Exact number: Enter the desired phone number and add it to the list.
Number ranges: Enter the area code in international format (e.g. +49 1579) and check Block all calls starting with this number.
In the block list overview, you can see all blocked numbers and edit or delete them.
Important: The block list applies to all users in the account. Only calls can be blocked via the block list, not incoming faxes. For the block list to work, your voicemail must be booked and activated.
Block phone numbers directly in the sipgate app
In the sipgate app (version 2.30.0 or higher), you can block individual phone numbers directly from the call list. To do so, move the mouse pointer over a call. In the menu, you will find the option "Block phone number", which automatically rejects future calls from this number. Already blocked numbers can be unblocked again via the same menu.
Please note that in the app you can only block individual phone numbers — blocking entire number ranges is currently not possible in the app.
