You are looking for support in configuring MO Spoofing Check in XSMOD, because when you try to send a message to another MSISDN, your number appears normally, the alphanumeric value does not appear.
In the current xs_mod configuration, you have configured returntype="moSpoofCheckMsisdn".
The issue is related to the xs_mod configuration . If the requirement is to replace the MSISDN in the incoming message with an alphanumeric value (spoof), the return type should be alphanumeric instead of mospoofcheck.
In order to do this, in the xs_mod configuration, please replace the value returntype="moSpoofCheckMsisdn" with returntype="alphanumericOriginator" and restart the xs_mod process.
This will resolve the issue.
