AUTOMATED ATTENDANT THAT SPECIFIES AUDIO TRANSMISSION CHARACTERISTICS FOR CALLS
The technology disclosed herein enables automatic specification of audio transmission characteristics for calls between endpoints. In a particular embodiment, a method includes presenting a query to a user of a first endpoint about a type of call to be established with a second endpoint. The type of call is one of a plurality of call types that respectively correspond to different audio transmission characteristics. The method further includes configuring an audio transmission characteristic based on a response to the query and establishing a call between the first endpoint and the second endpoint using the audio transmission characteristic.
1 . A method comprising:
presenting a query to a user of a first endpoint about a type of call to be established with a second endpoint, wherein the type of call is one of a plurality of call types that respectively correspond to different audio transmission characteristics;
configuring an audio transmission characteristic based on a response to the query; and
establishing a call between the first endpoint and the second endpoint using the audio transmission characteristic.
2 . The method of claim 1 , comprising:
receiving the response in a first signaling type;
wherein the audio transmission characteristic corresponds to the first signaling type.
3 . The method of claim 2 , wherein the first signaling type includes a teletype (TTY) character and wherein the query directs the user to select any key on a TTY device at the first endpoint to transmit the TTY character in response to the query.
4 . The method of claim 3 , wherein the query directs the user to select any Dual-Tone Multi-Frequency (DTMF) key to transmit a second signaling type comprising a DTMF signal.
5 . The method of claim 1 , wherein the response indicates that the type of call is teletype (TTY) and wherein configuring the audio transmission characteristic comprises:
selecting a TTY-compatible transmission characteristic.
6 . The method of claim 5 , wherein the query asks the user whether the type of call is TTY or voice and wherein a voice-optimized transmission characteristic for a voice-type call is different than the TTY-compatible transmission characteristic.
7 . The method of claim 1 , wherein establishing the call comprises:
transmitting a session invite to the second endpoint that requests the call to have the audio transmission characteristic.
8 . The method of claim 7 , wherein the session invite is a Session Initiation Protocol (SIP) invite.
9 . The method of claim 1 , comprising:
exchanging user communications between the first endpoint and the second endpoint over the call.
10 . The method of claim 1 , comprising:
initiating establishment of the call to the first endpoint.
11 . An apparatus comprising:
one or more computer readable storage media;
a processing system operatively coupled with the one or more computer readable storage media; and
program instructions stored on the one or more computer readable storage media that, when read and executed by the processing system, direct the apparatus to:
present a query to a user of a first endpoint about a type of call to be established with a second endpoint, wherein the type of call is one of a plurality of call types that respectively correspond to different audio transmission characteristics;
configure an audio transmission characteristic based on a response to the query; and
establish a call between the first endpoint and the second endpoint using the audio transmission characteristic.
12 . The apparatus of claim 11 , wherein the program instructions direct the processing system to:
receive the response in a first signaling type;
wherein the audio transmission characteristic corresponds to the first signaling type.
13 . The apparatus of claim 12 , wherein the first signaling type includes a teletype (TTY) character and wherein the query directs the user to select any key on a TTY device at the first endpoint to transmit the TTY character in response to the query.
14 . The apparatus of claim 13 , wherein the query directs the user to select any Dual-Tone Multi-Frequency (DTMF) key to transmit a second signaling type comprising a DTMF signal.
15 . The apparatus of claim 11 , wherein the response indicates that the type of call is teletype (TTY) and wherein to configure the audio transmission characteristic, the program instructions direct the apparatus to:
select a TTY-compatible transmission characteristic.
16 . The apparatus of claim 15 , wherein the query asks the user whether the type of call is TTY or voice and wherein a voice-optimized transmission characteristic for a voice-type call is different than the TTY-compatible transmission characteristic.
17 . The apparatus of claim 11 , wherein to establish the call, the program instructions direct the apparatus to:
transmit a session invite to the second endpoint that requests the call to have the audio transmission characteristic.
18 . The apparatus of claim 17 , wherein the session invite is a Session Initiation Protocol (SIP) invite.
19 . The apparatus of claim 11 , wherein the program instructions direct the processing system to:
exchange user communications between the first endpoint and the second endpoint over the call.
20 . One or more computer readable storage media having program instructions stored thereon that, when read and executed by a processing system, direct the processing system to:
present a query to a user of a first endpoint about a type of call to be established with a second endpoint, wherein the type of call is one of a plurality of call types that respectively correspond to different audio transmission characteristics;
configure an audio transmission characteristic based on a response to the query; and
establish a call between the first endpoint and the second endpoint using the audio transmission characteristic.
