I think this is a very valid point.

I would include ISUP & TCAP.  Ideally I would rather have my SS7 A- 
links terminate in a purpose built box (ss7box, Cisco 2600 with ss7  
software).  I would want Asterisk to handle the ISUP/TCAP over IP  
(SIGTRAN ??).   I think it will be nearly impossible to get Asterisk- 
ss7 certified by an RBOC for interconnect to their network.  Without  
certification it is only good as a toy in a lab scenario.   Using an  
existing box (cisco) would make the certification process much  
easier, unnessesary.
