Kannel : Group
You may not modify the group. If you want to configure another group you will have to go back to the previous page and go to the right icon.

* Core group consists of the main Kannel (bearerbox) configuration variables.

* SMSC group :
Kannel listens to one or more SMS Centers, a separate group must be defined for each of the SMS Centers. In addition, if any SMSC is connected, the smsbox-port variable in core group MUST be set.
CIMD centers are accessed via TCP/IP, so we need the hostname (or IP number) and port number to which we should connect. Similarly, old EMI centers are accessed via ISDN/modems, so we need the phone number to call and the Unix device file (e.g., /dev/ttyS0) where the modem is connected to the computer. We need both a username and a password for logging in to most of the SMS Centers (fake smsc does not need username nor password, nor does require some other centers which are accessed via TCP/IP).

* WAPBOX group :
If Kannel is supporting WAP, it must define wapbox connections. They are defined with following fields, of which some are optionnal.
Note that as new bearerbox is not yet supporting dynamic configurations nor uploading them into sms and wapboxes, sms and wapboxes should use the same configuration file as bearerbox when starting them up.

* SMSBOX group :
If Kannel handles any SMS messages, it must have defined smsbox group, with one or more of the following variables.

* SMS-SERVICE group :
These groups define SMS services in smsbox, so they are only used by the smsbox. Each service is recognized from the first word in an SMS message. By adding a username and password in the URL in the following manner 'http://luser:password@host.domain:port/path?query' we can perform HTTP Basic authentification.

* SENDSMS-USER group :
For smsbox, if any sendsms-services are used, there must be one or more accounts to use it.
