Pretty much any conventional PBX where you have conventional phones and 
don't want a timeout. Even most SIP phones don't have a SEND button even 
though the INVITE is en-banc under the hood, so you need a dialplan with 
a timeout.

IMHO, 9-8-8 is a boneheaded idea as it breaks NANP and causes ambiguity. 
In addition now that it's law look for all kinds of other mandated 
service codes. Lost your cat, dial 9-7-7. Need a jump start, 9-6-6, 
Alcoholics Anonymous 9-5-5, etc.
