Message Waiting Indication through Call-Control

The message waiting indication received on the SIP side is transported through the call control to the destina- tion FXS interface. Currently, the SIP interface is the only source of message waiting indication information and the FXS interface is the only possible destination of this information. The information is routed like a call through the call-control. Therefore, it must exist a valid routing path for a call from the SIP interface handling the NOTIFY to the destination fxs interface. This must be the case, because the phone connected to the FXS interface must be able to get calls from SIP before it makes any sense to get message waiting information for missed calls from SIP.

The message waiting information can be transported through routing-tables, service aaa, service limiter, service priority, service distribution-group and service hunt-group.

•In case of routing through routing tables, the message waiting information will reach the right destination only if the parameter according which the routing occurs is set to exactly the same value in an incoming INVITE request for that FXS interface as in the incoming NOTIFY request for that FXS interface.

•In the case of “called-e164”, this is surely the same, but pay attention to the manipulation of parameters.

•In case of service distribution-group, the message waiting information is transported to any valid destina- tion of the distribution-group.

•In case of service hunt-group, the message waiting information is transported only to the first destination of the hunt group.

•In any other of the named services, the message waiting information is routed transparently through.

If the message waiting information is routed to a destination service or interface which is not explicitly listed here, the information will be dropped.
