for instance, to move back and forth between the internal WLAN coverage and the mo-
bile radio network without the call being interrupted.
Integration step 1
• The mobile or external phone is assigned to a user and can be reached internally
using his user number.
• If the integrated phone user is assigned a direct dialling number, he can also be
reached from the outside.
• The status of assigned user is monitored and displayed internally (e.g. on team
keys). This is of course possible only for actively logged in phones or for calls to in-
tegrated phones set up via the internal user number.
• If the user of the integrated phone calls an internal user on his direct dialling num-
ber, the called party is shown the CLIP of the integrated mobile phone’s internal call
number.
• The external user of the integrated phone can dial in using specially set-up direct di-
alling numbers for which Mobile/external phone integration is configured as the
CDE destination; once the external user has been authenticated he obtains the in-
ternal dialling tone. He can then carry out specific functions via */# function codes in
prefix dialling or make internal/external calls. Several such direct dialling numbers
can be set up for each communication server or AIN. This can help to save consid-
erable roaming charges in an AIN that covers several countries.
• One Mobile or External Phone Extension licence is required for each integrated
phone.
Integration step 2
The integration level 2 has also all functions of the level 1. Suffix dialling functions such
as enquiry calls or setting up a conference are additionally possible. This requires spe-
cial DTMF receivers which must be activated throughout the connection. This in turn
requires DSP resources. This means that the following prerequisites are needed so
that the functions of integration step 2 can be used:
• The number of DTMF receivers required must be covered with GSM channels in the
DSP configuration (DSP ( =ym) view). The number of assignable GSM channels
differs depending on the configuration server and DSP (see Mitel 415/430 and
Mitel 470 System Manual).
• If all GSM channels are busy, the functions of integration level 2 for the current call
connection are not available.
