Using voice request
The voice request feature allows you to have a conversation with a person
at a remote fax machine during a fax communication. Either the sender or
receiver can initiate a voice request.
If you are sending a fax, you can answer a voice request only after all pages
have been transmitted. If you are receiving a fax, you can answer a voice
request after reception of each page.
You will know if the person on the other fax machine has issued a voice
request when you hear a warbling tone. If you do not respond in
approximately six seconds, the voice request is automatically cancelled.
