InboundCallRoute and filtering

[jafu]

Trying to filter out some calls.
555-555-1111 - Wanted Phone # calling wrong number despite our complaints
555-555-2222 - Wife's cell
555-555-3333 - A test line I'm using.
100 and 101    - Random spam/hangups

Wanted to filter out some 800 numbers too.  Using:  http://www.obihai.com/OBiAdminGuide.htm#_Toc333506159

And...

Set X_InboundCallRoute to:
{(10x.|1888xx.):},{(x.5555551111|x.5555553333):sp1(5555552222)},{ph}
restart, and
Rings 555-555-1111 when 555-555-3333 calls.

Yay!


Set X_InboundCallRoute to:
{(10x.|1888xx.|x.5555553333):},{(x.5555551111):sp1(5555552222)},{ph}

Still rings 555-555-1111 when 555-555-3333 calls.  I expected to get a busy signal.

Final configuration should be:
{(10x.|1888xx.:},{(x.5555551111):sp1(5555552222)},{ph}

However, I'm inserting my phone into the two rules to test them as late night calls bring the fail.

Thoughts?  Suggestions?  Corrections?
