Call handling features

Call transfer (blind/announced)

Enables a user to relocate an existing call to another user or external number after or before conferring with the recipient.

Call Forwarding

Redirects a telephone call to another destination, which may be any other extension or external telephone number. You can set forwarding on busy, on no answer, if not registered and unconditional.

Call Hold

Pause the current conversation. When the call is on hold, the other party listens to the music on hold.

Call Waiting

Suspend a telephone call already in progress to accept a second call. You may also switch between calls.

Secure call recording

Securely record every call or only specific calls. You can listen call recrods on-demand and share them with colleagues.

Group Call

In Ringotel apps you can create a group of users and/or external contacts and initiate a conference call anytime with a single button.

Works with NATs
