Unknown dest_addr_ton

Good day.

I have SMPP connection to SMSC, which sends me destination addres such
as NNNN#NNNNNNNN, where N is a digit, but
dest_addr_ton: 0 = 0x00000000 - "Unknown" ton
dest_addr_npi: 0 = 0x00000000

Than kannel sends back response with command_status: 11 = 0x0000000b.
I think it because of there are '#' in destination address.
In the source code of smsc_smpp.c there are statement which allow such
destination address only with dest_addr_ton: 5 = 0x00000005.
But as mention in GSM 03.40 ""Unknown" is used when the user or
network has no a priori information about the numbering plan. In this case,
the Address-Value field is organized according to the network dialling plan,
e.g. prefix or escape digits might be present."
So may be it means that # is allowed for "dest_addr_ton: 0" too?

I have made some simple patch.

May be i'm wrong but now it's work fine for me.
