11.4.2 MTC Number(s)
MTC stands for Mobile Terminated Call. One or more MTC Numbers (several number-
s/prefixes have to be separated with dashes, but no spaces) can be saved here.The
MTC Number will be associated as Caller ID for your corporate system (AMCC). You
could say that this is the identification the AMCC uses towards the AMC. If the MTC
Number is set, all Enterprise calls must come with this Caller ID otherwise they will not
be handled by the AMC. In order to make sure that the number is positively matched,
you have to enter your PBX number in international format. To enter more than one
MTC Number, separate them with dashes.
Use Case
The MTC Number or prefix identifies a call as an Enterprise (AMC) Call. All AMC
Solution features become available for identified Enterprise Calls.
11.4.3 Callback Number
Configure the number that is to be dialed to trigger a Callback without HTTPS. Like all
FMC Numbers, the Callback Number should be configured in international format, i.e.
with country code, to ensure that the AMC is always able to dial it independent on its
location. How to use this and other call types with the mobile phone in hand is explained
in section 8.5.
How it works
There are two ways to send the B-party number to the AMCC, either via an HTTPs
request over the data channel or via a regular call. After the AMCC has received the
number, the call setup is identical for the two scenarios. Below the simplified call sce-
nario is described.
