MMC Controller - General

Here you can define the interface to the AMC Controller.

Table 1. AMC Controller General settings
Parameter	Explanation
ID	Controller ID in the communication server’s configuration
IP address	IP address of the Controller
MMC hostname
MAC address
SIP port	SIP port of the Controller (default is port 11000)
Enable keep alive	The communication server periodically updates the NAT table on its own firewall using notification messages to the proxy server. This means that the system remains in constant contact with the Controller.
External IP (for NAT)
Transport protocol	Here you can select the transport protocol you want
Bandwidth control area	The assigned bandwidth area determines the codecs used on the WAN link to the Controller.
Relay RTP data via communication server	Indirect switching: During connection set-up to another IP endpoint, the voice data is forwarded via the communication server and not directly. This can help in solving NAT and firewall problems. Direct switching: During connection set-up to another IP endpoint, the voice data is forwarded directly. Note: Indirect switching requires two additional VoIP channels on the communication server.
Active line supervision (using session refresh)	Checks, with the session refresh method at regular intervals, whether connection to the remote station is still active. If the remote station does not react within the defined session refresh period, the connection is cut.
Number of mobile phone digits to match
User name
Password
Redirect server PIN

Table 2. MMCC Direct dialling number
Parameter	Explanation
DDI plan	The following dialling-in numbers must be created in a direct dialling plan. Here you can specify in which plan you opened them.
DDI	Dialling-in number for the MMC-Clients.
Callback	The MMC client uses this dialling-in number to trigger a callback on the Controller. Once the MMC user has answered the callback, he can dial the call number of the call party he wants using DTMF.
Call reverse	If the call reverse feature is activated, incoming calls are signalled to the MMC client, but not offered. Instead the Controller takes the call. As soon as the MMC user wants to answer the call, the MMC client sets up a connection to the Controller and the Controller connects the two calls.
SIM switch	In the Controller several SIM cards with different call numbers may be registered for one and the same MMC client. After a change of SIM card the MMC user can then inform the Controller which of the cards is now active.

Table 3. MMC client dial in numbers
Parameter	Explanation
DDI
Callback
Call reverse
SIM switch
MTC number	Enter as MTC number (MTC = Mobile Terminated Call), for instance, the main call number of the communication system.

Table 4. Extended settings
Parameter	Explanation
Disable inband DTMF detection
Registration timeout interval(s)
Listening SIP port
Listening TLS port
RTP start port
RTP end port
HTTP server port
Route for outgoing calls
Ignore CLIP of the caller	The MTC number is sent to the mobile phone instead of the caller CLIP. This makes the mobile phone to display the caller information transmitted via the MMCC data channel to the mobile phone. Note: This setting is only necessary if “Special Arrangement” (CLIP not screening) is not available at your network provider's. This is the case in Australia, for instance.
