I'm integrating Twilio's WhatsApp messaging service. I've completed all the configurations and SMS messages work correctly with EU numbers, but when trying to use Mexican numbers (+52), the module always adds (+1) to the destination number. I can't find any configuration settings for this issue. Has anyone been able to send WhatsApp messages to international numbers using the Twilio SMS and Alarm Notification module?

You may have to specify the contact number like this: `011-52-55-12345678`, which for me yielded `+525512345678` once it was passed to the routine that converts to E164 format.
