You have two commas there, which is not right, and might be a problem?

So, that is line 625...

And then it continues with lines 632..635??

The next context occupies lines 649..653, okay.

1. Try removing one of the two commas.

2. Take a copy of your dialplan, and then strip out *everything* except the 
one context and the one number you want to match:

[0705680837]
exten => 31705680837,1,NooP( Incoming 31705680837 on CC)
  same => n,Answer();
  same => n,Background(dit_is_het_nummer_van_de_familie_witvliet)
  same => n,Wait(1)
  same => n,Hangup()

3. Of course, make sure your sip.conf points this provider at the context 
(although that does seem to be working from the console output).

4. Turn on debug logging, not just verbose.
