How do I divert a call to the number 0171 1234567?

From your sipkom connection, dial:

• *1 0171123456 - to set the call diversion
• *10 - to disable the diversion
• *11 – to re-enable the diversion (for the same number)

Because the * function causes a problem for the Fritz!Box Fon for example, you can also dial 1151 instead of *1

• 1151 0171123456 to set the call diversion
• 11510 to disable the diversion
• 11511 to re-enable the diversion (for the same number)
