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. -- Jay Hennigan - jay at west.net Network Engineering - CCIE #7880 503 897-8550 - WB6RDV
