I am trying to establish our Mobile Channel through Campaign Classic, however our vendor told me that the last remaining issue is that we are sending mobile numbers with a leading 0. This causes the messages to error out in their system.
It appears that the leading zero is added to the recipient field itself and i am unable to remove it from the associated form. I have set up an Extended SMPP External Account and tried using different MT Acknowledgement and Encoding settings per this documentation: SMS connector protocol and settings -- however the leading 0 is not removed from the delivery address.
Is there a different setting in the External Account or something specific to the Recipient field that needs to be updated? What am i missing?
