Figure 1-25 Out of Range transfer Flow Chart
• When a call comes into an idle SIP terminal which has not been recognized as out of range, the
system waits for the timer in PRG24-02-15 (default 4sec) to expire to determine if the terminal is Out
of Range state or not.
• When the SIP terminal starts ringing and then moves to out of range, the terminal keeps ringing
because the terminal is no longer under the control of the system. In this case the Out of Range
transfer is not applied.
• Out of Range transfer is applied to an individual call only, group incoming calls or paging calls to a
SIP terminal are not applied.
• In case of Ring Transfer to the SIP terminal Out of Range transfer is not applied. It follows No
Answer timer in PRG24-02-03.
• In case of internal call from other standard SIP terminal, lock-out tone is not applied. Caller hears
Busy Tone.
NAT Mode for SIP Phone
• Plug and Play function for remote router is supported as well as NAT feature for SIP MLT.
• When PRG 10-33-05 NAT mode for SIP Phone is set 1 = Enable, P2P mode for SIP Phone
