> Subject: [BLISS] Rejection conditions for ACH
> 
> During BLISS ACH (automatic call handling) design team 
> discussions at the last conference call a provisional set of 
> rejection conditions was identified for which appropriate SIP 
> response codes need to be identified. Only conditions 
> typically expected to influence ACH at a proxy are included. 
> The conditions need to be agreed before attempting to select 
> response codes. The following conditions have been identified:
> 
>           <t>Busy. UA resources are busy as a result of 
> another call and further calls cannot be accepted until 
> resources become free. The condition may also be visible via 
> a presence system.</t>
>           <t>Do not disturb. The user has indicated in 
> advance an unwillingness to receive calls and therefore calls 
> cannot be accepted until the user indicates that the 
> condition has been lifted. A user may impose such a condition 
> during a meeting or while working on a critical task. The 
> user may indicate in advance a time at which she expects the 
> condition to be lifted. The condition may also be visible via 
> a presence system.</t>
>           <t>Local rejection. The user has responded to this 
> call by rejecting it. Whether this impacts other branches 
> (e.g., other UAs registered for that AoR), forwarding to 
> voicemail, forwarding to an assistant, etc. depends on the 
> proxy configuration. A user would use this facility when not 
> in a position to answer a particular call or when she feels 
> that it would be better handled elsewhere (e.g., by 
> voicemail, by an assistant). The fate of the call will depend 
> on proxy ACH settings.</t>
>           <t>Global rejection. The user has responded to this 
> call by rejecting it with the preference that all other 
> branches should be cancelled and forwarding to voicemail, 
> forwarding to an assistant, etc.
> should not take place. A user would use this facility when 
> she is unwilling to handle a particular call and does not 
> wish it to be handled elsewhere. A user would typically use 
> this facility for unwanted traffic. The fate of the call will 
> depend on proxy ACH settings, but typically it will result in 
> outright rejection.</t>
> 
> Please comment on this set of conditions.
