If you don’t want to send a plus, don’t include it in the string. ---

Please use unformatted text markup to prevent # being treated as markup for a heading line. What you have should do what you want if the dongle understands it. What does verbose logging show as the expansion of the variables, and what does sip set debug on show as the actual request URI? ---

Enable detailed tracing on the channel and see if the number is being sent. (You may find you need to use a USB protocol logger.) Look at the verbose log and see if the correct number is being passed to the application. ---
