and User Configuration
Overview, Installation and User
AltiGen’s MaxMobile Communicator application, installed on a G1 phone
based on Google’s Android platform, makes the phone a fully capable
office phone extension and serves as a “desktop” call control client,
allowing you to access, configure, and perform most of your company's
PBX functions directly from the graphical user interface in MaxMobile
Communicator. This includes call handling, call forwarding, conferencing,
conversation recording, directory and contact lookup and dial. In addition
MaxMobile Communicator lets you save Favorites.
MaxMobile Communicator runs on any mobile phone device that is using
the Android operating system. When you log in, it connects your Android
phone to your company's MAX Communication Server (MAXCS) as a
native extension of the system. If you have a desktop phone with the same
extension, calls to this extension are now routed to your Android phone as
long as you are logged in to MaxMobile Communicator. When you log out,
those calls are again routed to your desktop phone.

MaxMobile Communicator User Guide 1
Like a remote extension, the G1 phone running MaxMobile Communicator
serves as an office extension, making and receiving calls through the public
switched telephone network (PSTN) to and from your company’s MAXCS
system. You can call company extensions (both inside and remote
extensions) just by dialing the extension number. Your calls to destinations
outside the company can go through the MAXCS system, as illustrated in
Figure 1, if you so choose.

This chapter is for the MAX Communication Server (MAXCS) system
administrator. The system administrator needs to configure MAXCS to
establish connections with MaxMobile Communicator on the Android
phone. The administrator should follow the instructions in the MAXCS
Administration Manual for configuring Mobile Extension settings, and
include the following:
1. Create Mobile Trunks. Select a trunk and configure it as a mobile
trunk. The trunk line number registered in PSTN is very important. It
will be used by MAXCS to verify whether a call is a mobile call.
2. Create an extension for the MaxMobile Communicator user.
MaxMobile Communicator uses the extension number and password
as ID to log in to the MAXCS system.
3. Assign an Altigen MaxMobile license to the extension. To do this,
from the MaxAdmin main menu, select License > Client License
Management. In the Client License Management dialog box, select
MaxMobile in the License Types column, and add the appropriate
extension to the Members list.
