Hello, I've searched the forum and tried almost everything i can think off, but i can't transfer to an outside line. I've made an extra extension ie. 123. and select forward all calls to oudside number. i've filled in my cell phone number in the outside number block. ie. 0612345678 . This is a dutch cellphone number without any extra prefixes. And i think that's where the problem is. Do i need to put an string or prefix in front of that number??
