Hi my sip provider is having issues with our ddis (they are all ringing to default 500) it appears they are sending +44207xxxxxxx format and cannot strip and replace at the moment??? and they have asked me to change my end. (it has been working for a year or so) I can't see anywhere within country code or ddi table where the + sign is accepted in 2.1.5 or 3.2.3 Is this something that cannot be done on the Samsung OS ?

Any feedback greatly appreciated!
