System functions and features as of R4.1
syd-0570/1.2 – R4.1 – 08.2016
Calls with the Internal ringing pattern:
• Calls from internal users
• Calls from the public network to analogue terminals if the interface configuration
( =7g) of the parameter Ring pattern is set to Single ringing tone.
• Calls from users from the private network (PISN users):
– Calls from the private leased-line network
– Calls from virtual network PISN users
•
An enquiry call from a user with an exchange call on hold if in the signalling settings ( =nr)
the parameter Ringing pattern at enquiry destination is set to Internal ring melody.
Calls with the external ringing pattern:
• Call from the public network
• An enquiry call from a user with an exchange call on hold if in the signalling settings ( =nr)
the parameter Ringing pattern at enquiry destination is set to Internal ring melody.
The Ringing pattern at enquiry destination setting is valid throughout the system.
Note:
Certain terminals which automatically answer calls (e.g. fax machines) are not able to interpret the
double ringing tone correctly. With these terminals the configuration Ring pattern = Single ring-
ing tone can be used to force a situation where the single ringing tone is always used for all calls.
Alternative for the MiVoice 5300, MiVoice 5300 IP series of system phones and the
MiVoice 2380 IP IP softphone
Different ringing melodies can be configured separately in the terminal configuration for
each system phone to help differentiate between internal and external calls. If the pa-
rameter External ring melody is deactivated, the single and double ringing tone is
used to make the distinction; otherwise, the configured ringing melodies. If no distinc-
tion 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 configura-
tion is used to decide whether the call is signalled internally or externally ( NPI call
unknown setting).
