Establishing audio communication sessions

1. A method comprising:

providing, to a first user of a communications system, ea first messaging user interface;

receiving, from the first user by way of the first messaging user interface, a message; and

providing, using one or more processors, the message to a second user of the communication system by way of a second messaging user interface;

enabling, within the first messaging user interface, a first selectable option for initiating an audio communication session with the second user based on audio communication capabilities of the second user;

detecting a selection of the first selectable option by the first user;

enabling, within the second messaging user interface and in response to the selection of the first selectable option, a second selectable option for accepting the initiation of the audio communication session;

detecting a selection of the second selectable option by the second user; and

initiating, in response to the selection of the second selectable option, the audio communication session between the first user and the second user using more than one channel including at least a generic signaling interface channel.

2. The method of claim 1 , further comprising presenting, to the first user, one or more screen names by way of the first messaging user interface, wherein the one or more screen names represent one or more other users of the communication system.

3. The method of claim 2 , further comprising receiving, from the first user, a selection of a screen name associated with the second user.

4. The method of claim 1 , further comprising determining an online status of the first user or the second user.

5. The method of claim 1 , wherein the audio communication capabilities of the second user comprise a capability to receive audio data based on one or more hardware requirements, one or more software requirements, or one or more selectable preferences.

6. The method of claim 1 , further comprising enabling, within the first and second messaging user interfaces, a third selectable option for ending the audio communication session.

7. The method of claim 6 , further comprising:

detecting a selection of the third selectable option by either the first user or the second user; and

ending the audio communication session in response to the detected selection of the third selectable option.

8. The method of claim 1 , wherein the more than one channel further comprise a control channel.

9. The method of claim 8 , wherein the more than one channel further comprise an audio channel.

10. The method of claim 9 , wherein at least one of the control channel or the audio channel comprises a TCP/IP socket.

11. A method comprising:

maintaining, for a first computing device associated with a first user of a communications system, data representative of one or more audio communication capabilities of the first computing device;

maintaining for a second computing device associated with a second user of the communication system, data representative of one or more audio communication capabilities of the second computing device;

providing a messaging user interface to the first computing device;

presenting one or more messages between the first user and the second user within the messaging user interface;

selectively enabling, within the messaging user interface, an audio communication option based on the audio communication capabilities of the second computing device and the audio communication capabilities of the first computing device;

detecting a request, from the first user and by way of the enabled option, to begin an audio communication session with the second user of the communications system; and

initiating, in response to the request, the audio communication session between first user and the second user using more than one channel including at least a generic signaling interface channel.

12. The method of claim 11 , wherein the audio communication capabilities of the second computing device comprise an online status of the second computing device.

13. The method of claim 11 , wherein the audio communication capabilities of the second computing device comprise one or more selectable preferences.

14. The method of claim 13 , wherein the one or more selectable preferences comprise preferences for blocking audio communication sessions with one or more specified users.

15. A system comprising:

at least one processor; and

at least one non-transitory computer readable storage medium storing instructions thereon that, when executed by the at least on processor, cause the system to:

provide, to a first user of a communications system, a first messaging user interface;

receive, from the first user by way of the first messaging user interface, a message; and

provide, the message to a second user of the communication system by way of a second messaging user interface;

enable, within the first messaging user interface, a first selectable option to initiate an audio communication session with the second user based on audio communication capabilities of the second user;

detect a selection of the first selectable option by the first user;

enable, within the second messaging user interface and in response to the selection of the first selectable option by the first user, a second selectable option to accept the initiation of the audio communication session;

detect a selection of the second selectable option by the second user; and

initiate, in response to the selection of the second selectable option, the audio communication session between the first user and the second user using more than one channel including at least a generic signaling interface channel.

16. The system of claim 15 , further comprising instructions, that when executed by the at least one processor, cause the system to present, to the first user, one or more screen names by way of the first messaging user interface, wherein the one or more screen names represent other users of the communication system.

17. The system of claim 16 , further comprising instructions, that when executed by the at least one processor, cause the system to receive, from the first user, a selection of a screen name associated with the second user.

18. The system of claim 15 , further comprising instructions, that when executed by the at least one processor, cause the system to determine an online status of the first user or the second user.

19. The system of claim 15 , wherein the audio communication capabilities of the second user comprise a capability to receive audio data based on one or more hardware requirements, one or more software requirements, or one or more selectable preferences.

20. The system of claim 15 , further comprising instructions, that when executed by the at least one processor, cause the system to enable, within the first messaging user interface or the second messaging user interface, a third selectable option for ending the audio communication session.

21. The system of claim 20 , further comprising instructions, that when executed by the at least one processor, cause the system to:

detect a selection of the third selectable option by either the first user or the second user; and

end the audio communication session in response to the detected selection of the third selectable option.
