AMCC-Side

This number has to be conﬁgured for the PBX Dialing-in purpose on the

AMCC!

E.164 Format

The PBX Dialing-in Number has to be conﬁgured in E.164 format to ensure

that the AMC is always able to dial it independently from its location.

12.1.2 SIM Switch Number

If you select Activate SIM Card in the main menu, the AMC uses this number to com-

municate to the AMCC that a new SIM card has been inserted. If the number of this

SIM card is conﬁgured for your User Account on the AMCC, your new SIM card will be

activated and you will be able to take advantage of the features of the AMC Solution.

Advantage of SIM Switch

All of the services offered by the AMC are exclusively available for conﬁgured users.

However, some users might have several SIM cards, mostly for taking advantage of

lower tariffs in different countries. It is possible to conﬁgure up to ten cell phone (SIM

card) numbers per user, but only one at a time will be "active".

How it works

A call to SIM Switch number is placed and hung up immediately. This guarantees

that the call is free of charge since it is never really established. If the SIM Switch

request was unsuccessful, you will not be able to make calls from now on, since the

AMCC cannot authenticate you. Such a failure should not happen, unless your new

SIM number was conﬁgured incorrectly on the AMCC.

What to do if SIM Switch doesn't work

If Automatic Start is activated, and if the SIM card requires PIN activation, the

AMC won't detect the new SIM card until the AMC was restarted. Restart the

AMC to see if the problem persists.

Your previously used SIM card will continue to work, unless there is a problem

on the AMCC-side: Check if there is a temporary problem by reinserting the

former SIM card. If it does not work, the error is likely to be located at the

AMCC.

If repeated attempts to Activate SIM Cards fail and if the conﬁgured number

of the second SIM card is correct, the reason could be an improper Caller ID

sent from your new SIM card. In those cases the switch has to be conducted

manually on the AMCC.
