LAI commands

Last Updated : Sep 11, 2012 |
LAI uses the commands included within the basic Call Vectoring and Call Prompting features:
  • route-to number with coverage n or route-to digits with coverage n command on Communication Manager that has LAI enabled and that successfully seizes an ISDN trunk automatically results in a normal LAI call attempt being placed. The call attempt can be rejected or accepted by the remote end.
  • route-to number with coverage y or route-to digits with coverage y command does not result in an LAI call attempt. The command always completes the call. Do not use the command when the vector at the receiving location ends up denying the call since the caller will hear a busy signal, or the call will disconnect. Use the command with coverage set to y only for those cases when an unconditional interflow is wanted (with LAI active) and the terminating Communication Manager is set up to handle this type of call.
When a LAI call attempt is made, Call Vectoring at the sending location checks a potential receiving location to determine whether to hold or send the call. While this is done, the call remains in queue at the sending location. As such, the call can still be connected to the sending-location agent if one becomes available before the receiving location accepts the call.
Call Vectoring at the receiving location determines whether to accept the call from the sending location or to instruct the sending location to keep the call. In the latter case, the sending location can keep the call, check other locations, or provide another call treatment. Conditions for sending, refusing, or receiving a LAI call attempt can include a combination of any of the following:
  • Expected wait time for a split.
  • Number of staffed or available agents for a skill.
  • Number of calls in queue.
  • Average speed of answer or the number of calls active in a VDN.
  • Time of day and day of week.
  • Any other legitimate conditional.
If the call is accepted by the receiving Communication Manager, the call is removed from any queues at the sending Communication Manager and call control is passed to the receiving Communication Manager. If the call is denied by the receiving Communication Manager, vector processing continues at the next step at the sending Communication Manager. Until the call is accepted by either Communication Manager, the caller continues to hear any tones applied by the sending Communication Manager. If the call is denied, the call vector can apply alternate treatment, such as placing another LAI call to an alternate backup Communication Manager.
Note:
The LAI operation is completely transparent to the caller. While a LAI call attempt is being made, the caller continues to hear any audible feedback that is provided by the sending Communication Manager vector. The caller also maintains position in any split queues until the call is accepted at the receiving Communication Manager.
LAI passes Call Prompting digits collected in the sending Communication Manager to the receiving Communication Manager by codeset 0 user information transport.
