Hello,
 
A minor comment:
 
> It is uncertain how the use of overlap within SIP, as defined here, would reduce the call establishment delay. The 
> last digit can not be forwarded at the destination SIP gateway until the final T10 expires, 
 
The use of the overlap sending to address the end point is useless anyway as the end point can not be identified until the complete number is received. The SIP overlap is only applicable for the transit case, where the next hope can be identified by the incomplete hierarchical number.
 
Greeting,
Denis Alexeitsev
