Hi, Please ignore the previous email. The figure in this
email must be a readable one. Sorry for the inconvenince. The draft
- draft-roach-sip-acb-00.txt, explains the Automatic Call Back (ACB)
Service in SIP with examples. This implementation moves the feature inteligence
to the SIP end users. The SUBSCRIBE/ NOTIFY will be transacted between the End
Users. I am planing to have this feature as a centralized
one. This means, ACB application will run over the SIP Proxy and all the end
users can access this feature. The inteligence will be centralized.
Please see the figure below for the message flow during the proposed ACB. User1 Proxy User2 Application |
|
| (1)Invite
|(2)Invite |
-----------� | -----------� |
| (3)Busy |
(4) Busy | �------------------- | �-------------------| | (5)Registr ACB at Usr2 | ---------------------�| |
|
(6)Registers for Application |
| ------------------------------------------------� |
|(7)If Usr2 sends BYE, let me know |
| �---------------------------------------------- |
|(8)BYE |
| �-------------------- |
|(9) Usr2 released the call |
| ------------------------------------------------� |

[] Start
3rd party Application,establish |
|
call between Usr1 and Usr2. | In the figure I am interested in Msg 5 only. Upon receiving the Msg-5, the Proxy
will send this information to Application. The Msg 5 must be a feature stimulus
method. Similar methods will be useful while activating/de-activating the
features over the signaling path in SIP. Can anybody please suggest the SIP methods/ Fields
that can be used for this purpose? please send me the document details if any,
available? I would appreciate the help in this regard. Regards, Prasanna |
