Pjsip trunk with @ in username

Hello, i have start to move my trunks to pjsip. One of my providers use the symbol @ in the username. So the username is like a email (for example [email protected]) However as far i have see in my tests in pjsip the @ is not allowed in username. How i can solve this? It is any way to bypass this? Thank you

Test your original register string (your third posting with the screenshot) first and just replace 2x@
