SMS: Substitution of address
I am working in the UK with a system where the external SMS account requires SMS phone numbers prefixed 44(number). When I try to send an SMS proof using a 44(number) via "Substitution of Address" Adobe is converting the number to 0(number) and the external account refuses to send. It does this whether I use 0044(number) or +44(number) or 44(number) as the phone number to use. I think this must be some configuration issue. Does anyone know what needs to be changed?
