help me

[Rodrigue Ango]

hello
I'm new to kannel, I had to cross many obstacles but this morning I had two new 
ones. I receive messages but when I try to send I have an answer: 
"Authorization failed for sendsms" yet user name and password created in the 
group sendsms-users is exact. The second problem is that I can not route a 
message to the recipient I have an answer: "No client - multi-send or ACK to 
pull-reply". please I need your assistance to be able to cross this barrier
