Abstract
Aspects of the subject disclosure may include, for example, generating a tone during first communications with another communication device, providing the tone to a gateway to cause the gateway to transmit a re-invite message without the gateway providing the tone to the other communication device, receiving the re-invite message where the re-invite message includes a request for a higher bandwidth than the first communications, providing a response message to the gateway responsive to the re-invite message where the providing of the response message causes the gateway to provide the tone to the other communication device. Other embodiments are disclosed.
