We are testing mod_smpp using  a kannel smpp server. We have two issues:

1. When kannel sends a message with deliver_sm with sequence number = 0, the mod_smpp receives the message with all the parameters set to 0 and throws error ""mod_smpp_gateway.c:257 smpp: error decoding the receive buffer: .. invalid sequence number". Is there any way we can resolve this issue?

2. After mod_smpp establishes a bind to the server, it does not send enquire_link. It will always time out and rebind again. As smpp client, it should be sending enquire_link to keep the connection alive. Is there any way we can enable the enquire_link in the module configuration?

Thanks for your help.
