SMPPCLIENT_UNEXPRESP status returns on Bind

[bassmaster]

Hello!

Which cases when SMPPCLIENT_UNEXPRESP status returns?
In my case I did execute Bund and receive following log:

17:45:20: SmppClient connected
17:45:20: Binding SmppClient for SystemId: ******
17:45:20: Bad status returned during Bind : BindTransceiverResp with status SMPPCLIENT_UNEXPRESP
17:45:20: Sending Data: 00000025000000090000000052dc26c74944206c7578646c68003132333435000034000000
17:45:20: SmppClient disconnected

What is it means?

Thanks.
