It's not unusual in old-school PBXs and wireline POTS where digits are <br>
processed serially. With cell phones dialing is en-banc with a SEND <br>
button so digit patterns no longer need to be unique. See note on <br>
en-banc dialing below.<br>

This did take some special programming, however. The leading 9 is a <br>
trunk access code and should return a second (often different sounding) <br>
dial tone. The law to which you refer is because of PBXs that weren't <br>
specially programmed to re-insert the stripped "9" and send the call on <br>
its way. The original expectation was "Seize an outside line (by dialing <br>
9) wait for dial tone, dial 9-1-1."<br>
<br>
When I was programming Mitel PBXs back in the day, I ensured that both <br>
9-11 and 9-911 would get routed to 9-1-1 regardless.<br>

Kinda, sorta. 7-digit local dialing is supposed to have been phased out, <br>
with all NANP numbers represented as 1+NPA-NXX-XXXX.<br>
<br>
This means that after your trunk access 9, you should expect a 1 <br>
(followed by ten digits for a regular phone number), a 0 for operator or <br>
011 international, or a three-digit code starting with 2 or 9 that until <br>
this week always ended in 11.<br>

<br>
Program 88 as a sequence to re-insert the stripped 9 and send <br>
immediately on trunks accessed by a 9, just like you do with 11.<br>
<br>
If you still want to allow 7-digit dialing and have a local 88X prefix, <br>
or if your dialplan allows 10-digit calls without a leading 1, then yes, <br>
you'll need a timeout. Or make it 9-988 until they pass another law.<br>
<br>
Note: In fact, en-banc cell dialing broke a few advertisements where a <br>
word was spelled longer than 7 digits. For example, "Dial <br>
1-800-HARDWARE" worked fine from a landline or (with prepended 9) from a <br>
PBX. As soon as the digits 1-800-427-3927 were dialed, the call would <br>
complete. With a cell phone, however, the number sent is 1-800-427-39273 <br>
which doesn't match a valid number and the call would be rejected. Some <br>
cellular carriers have worked around the issue and truncate long strings <br>
to match the NANP.<br>
