[SOLVED] Cannot setup Apache Camel SMPP to receive messages from SMSC node using GSM-7

Cannot setup Apache Camel SMPP to receive messages from SMSC node using GSM-7

This question is regarding Apache camel SMPP and GSM-7

using camel-smpp-starter 4.2.0

Our SMSC sends sms messages to our application using SMSC Default Alphabet according to the header. This is according to SMSC docs GSM-7. When I try to set encoding to GSM-7. it throws an error. I can see that the code uses String(body, ) to decode the body.

I'm wondering if anyone has used camel smpp with GSM-7 and could provide some details

camel:
springboot:
main-run-controller: true
component:
enabled: true
smpp:
encoding: GSM-7

Solution

Answering this myself:

the apache camel smpp component doesnt support gsm-7, it only supports formats installed in the jvm out-of-the-box. What we did was to change the config of the smsc to send messages in latin1 format.
