70  * Kannel
71  *
72  * This type allows concatenation of Kannel instances, ie:
73  *
74  * <smsc>--<bearerbox2><smsbox2>--HTTP--<smsc_http><bearerbox1><smsbox1>
75  *
76  * Where MT messages are injected via the sendsms HTTP interface at smsbox1,
77  * forwarded to bearerbo1 and routed via the SMSC HTTP type kannel to
78  * sendsms HTTP interface of smsbox2 and further on.
79  *
80  * This allows chaining of Kannel instances for MO and MT traffic.
81  *
82  * DLR handling:
83  * For DLR handling we have the usual effect that the "last" smsbox instance
84  * of the chain is signaling the DLR-URL, since the last instance receives
85  * the DLR from the upstream SMSC and the associated smsbox triggers the
86  * DLR-URL.
87  * For some considerations this is not what we want. If we want to transport
88  * the orginal DLR-URL to the "first" smsbox instance of the calling chain
89  * then we need to define a 'dlr-url' config directive in the smsc group.
90  * This value defines the inbound MO/DLR port of our own smsc group and
91  * maps arround the orginal DLR-URL. So the next smsbox does not signal the
92  * orginal DLR-URL, but our own smsc group instance with the DLR, and we can
93  * forward on to smsbox and possibly further on the chain to the first
94  * instance.
95  *
96  * Example: (consider the 2 chain architecture from above)
97  * A MT is put to smsbox1 with dlr-url=http://foobar/aaa as DLR-URL. The MT
98  * is forwarded to bearerbox.
99  * If no 'dlr-url' is given in the smsc HTTP for the next smsbox2, then we
100  * simply pass the same value to smsbox2. Resulting that smsbox2 will call
101  * the DLR-URL when we receive a DLR from the upstream SMSC connection of
102  * bearerbox2.
103  * If 'dlr-url = http://localhost:15015/' is given in the smsc HTTP for the
104  * next smsbox2, then we map the orginal DLR-URL into this value, resulting
105  * in a dlr-url=http://lcoalhost:15015/&dlr-url=http://foobar/aaa call to
106  * smsbox2. So smsbox2 is not signaling http://foobar/aaa directly, but our
107  * own bearerbox1's smsc HTTP port for MO/DLR receive.
