Configuring the Telephony Gateway
The basic setup recommended here is essential to the telephony gateway
functioning. After the MobileLAN voice system is running, you may
want to configure additional parameters to adjust the system for your
network. For help, see the MobileLAN voice System User’s Guide.
To configure the telephony gateway
1. From the main menu, select Gateway Configuration. The Gateway
Configuration screen appears.
2. Use the worksheet for the telephony gateway to enter these
parameters:
Option Description
IP address Enter the IP address for the telephony gateway,
including numbers and periods. This address is
assigned by your system administrator.
Hostname (Optional) Enter the hostname for the telephony
gateway if you want to change the default name. You
cannot enter spaces. This name is used for
identification purposes only.
Subnet mask Enter the subnet mask for the telephony gateway,
including numbers and periods. This subnet mask is
assigned by your system administrator. This field is null
in the MobileLAN voice system.
Telephone switch type Press Enter to change this field. From the submenu of
PBX types, select the telephone switch type you are
using.
Phones per access Enter the maximum number of active wireless
point telephone calls per access point. Intermec’s 21XX
universal access points can handle up to 7 calls.
Companding type Press Enter to change this field. From the submenu of
signal compression type, select the companding type
you are using.
Mu-law is the standard format in most host telephone
systems in North America.
A-law is typically used in Mexico and Europe.
Note: If the companding type of the telephony gateway does not
match that of the PBX, the wireless telephones will have dis-
torted dial tone and unintelligible voice quality.
