Fig. 20 - Service mobility extension function “SMS at no answer”
Fig. 20 shows the sending of information texts if an incoming call
is not taken.. Subscriber A calls subscriber B, who has the
permitted service of mobility extension with activated services
“Follow me” and “SMS at no answer”. Subscriber B does not take
the call in the VoIP network, and so the call is rerouted to his
mobile telephone. Subscriber B does not take the call even on his
mobile telephone, and so he is sent a text announcement telling
him that the call from subscriber A had been missed.
Function of forwarding call
In addition to the rerouting of calls in the event of absence, the
function mobility extension allows calls to be forwarded within a
VoIP network, which brings the services of the SIP proxy to a
mobile telephone. The description of this function is displayed in
Fig. 21.
