Exclude rule works...but sometimes too well.

[GoogleCodeExporter]

OK.  Let me preface:
Nexus S running 2.3.2
Exclude rule syntax: \A\+972,0

I live in Israel. I have setup SipDroid to exclude all numbers starting with 
+972 or 0 (local israeli numbers)

This way if I open my native contact app and choose a local number the native 
dialer works. If I choose a US number (starting with +1) it should dial using 
SipDroid)

What I find weird is that when it comes to calling US numbers it isn't 
consistent.  Sometimes it will dial with SipDroid and sometimes not.  I can't 
find a reason for this because all my US numbers are entered in the same format 
in my contact list (+1-xxx-xxx-xxxx).

If I open SipDroid and actually type in the number to dial it works fine.  But 
if I open SipDroid (or native contacts) and CHOOSE a US number to dial from the 
contact list it's not guaranteed to use SipDroid to dial.  Many times it will 
just open the native dialer.  

A single contact may have two numbers (mobile and home), both numbers being 
+1-areacode-number, one number will dial using sipdroid and the other with the 
native.  I reiterate, they are entered in the exact same format so there 
shouldn't be a difference.

Any idea what's wrong?
