Route Incoming SMS To Kannel Gateway

Hello.

One customer already has a SMPP server with SMPP credentials, can i give them a username/password and then when i receive the SMS can i point all the SMS to Kannel (outbound gateway).
If, yes then can anyone please let me know the steps ?
Thank you.

Can anyone please guide me on how to achieve this ?

any help please, i need to receive SMPP SMS and send it to my Kannel SMPP provider.

You need a smpp server. Look for opensmppbox, or ksmppd, both acts as kannelĀ“s boxes, providing you a smpp server.
