This Page shuld describe a fromfwdOUT-Context for Germany.
Problem
- you must replace 49xxxxx to 0xxxxx in the dialed extension (because 49 is the area code for germany, but it does not work when you are in germany)
- you must catch all value added services numbers
Numbers to be catched (and not dialed)
(see also http://de.wikipedia.org/wiki/Liste_der_deutschen_Telefonvorwahlen )
- 490 – international call prefix (00)
- 491 – special Numbers without fixed desination
- 4910 – Call-by-Call-Numbers e.g. 01033 (dt. telekom), 010050, etc.
- 4915 – Mobile Phone – UMTS?
- 4916- Mobile Phone
- 4917 – Mobile Phone (0172, 173, 174, 0175)
- 4918 – Shared cost numbers
- 4919 – old Premium Rate Numbers
- 49310 – Service-number
- 49311 – Service-number
- 4932 – IP-Numbers (cost: at this time unknown, better to be dialed directly!)
- 49700 – “universal Number” – allowes the ownder to be forwarded to an arbitrary number
- 4990(0) – new Premium Rate Numbers (except: 49906 Donauwörth)
- 49902 – Televotum / Teledialog
