The algorithm for determining the address type is below. The following
excerpt is taken from PDUUtils.java
The type-of-address is determined by OR'ing 0x80 with the addressType
and number plan.
The algorithm here is actually was built around the circumstances of
the telco networks here in the Philippines. There are actually other
values for the number plan I think (not sure if there are other
address types as well) but they are not included here. If there are
differences in the foreign network values let me know and we'll see if
something can be done.

// some typical ones used for sending, though receiving may get other
types
// usually 1 001 0001 (0x91) international format
// 1 000 0001 (0x81) (unknown) short number (e.g. access
codes)
// 1 101 0000 (0xD0) alphanumeric (e.g. access code names
like PasaLoad)
