When sending a message with an alphanumeric sender id, the source address is not shown correctly on the phone.
The problem is caused by incorrect 'source_addr_ton' and 'source_addr_npi' values. When 'source_addr' contains non-numeric symbols, 'source_addr_ton' and 'source_addr_npi' should be set AddrTon.ALPHANUMERIC and AddrNpi.UNKNOWN
