Alternative for the Aastra 5300, Aastra 5300ip series of system terminals and
the Aastra 2380ip IP softphone
Different ringing melodies can be configured separately in the terminal configura-
tion for each system terminal to help differentiate between internal and external
calls. If the parameter
External ringing melody
=
0
, the single and double ringing
tone is used to make the distinction; otherwise, the configured ringing melodies. If
no distinction is required, the identical melody can be entered in both places.
Identifying the Origin of a Call
If an incoming call's CLIP number corresponds to numbering plan identifier E.164,
the system assumes that the call comes from the public network.
If an incoming call's CLIP number corresponds to numbering plan identifier PNP,
the system assumes that the call comes from the PISN.
If the CLIP number’s numbering plan identifier is unknown, the trunk group config-
uration is used to decide whether the call is signalled internally or externally (
NPI
call unknown
setting).
