In general, a channel option file contains site-specific parameters required for the operation of the channel. A channel option file is not required for SMS. If you determine that one is necessary for your installation, store it in a text file in the installation-directory/config/ directory. As with other channel option files, the name of the file takes the form:
channel_name_option
For instance, if the channel is named sms_mway then the channel option file is:
installation-directory/config/sms_mway_option
Each option is placed on a single line in the file using the format:
option_name=option_value
For example,
PROFILE=GSM SMSC_DEFAULT_CHARSET=iso-8859-1 USE_UCS2=1 |
