Are you referring to the plus sign?
You may want to check the trunk settings - under "Identity". There is a toggle for the plus sign under Called - "Address Omit + Prefix". Maybe check to see if that is toggled on or off.
Sorry, I'm no expert - just saw that no one had responded and I know we have the plus sign format and we can use the call back button.
