Hi Rodrigo, First of all thank you for your time.
It is very difficult to check if the TCP connection with the SMSC is up because that error is not very usually and when I see the error in the logs the connection is already reestablished by kannel. Anyway if the connection was broken I guess that the enquire link send by kannel should appear in the logs without its correspondig enquire link resp from smsc or, at least, kannel should try to reconnect inmeadtly and not 300 seconds after. Am I wrong about this ?
