tell the telco how many digits to send.<span style='font-family:"Calibri","sans-serif"'> </span>
Often times, at least in my experience, if not specified, they will only send
the last four providing there are no conflicts.<br>
<br>
They should be able to send however many digits you require, but maybe they
wont.<o:p></o:p></p>

and in fact each CO, may have a different practice for how many<br>
digits they send. If you have a good sales person when you place the
order you can specify, or<br>
at least they will provide that information. If you have an uninformed
sales person, the engineer<br>
who sets up you circuit can usually provide that. If you end up with uninformed
sales and engineering<br>
personnel, then it is time to test and debug.<o:p></o:p></span></p>

rewrite the received number to prepend the missing digits. It is a little
more work for<br>
me, but it reduces the chance that future maintenance by the telco will revert
the<br>
circuit back to their normal values and bust inbound calls.<o:p></o:p></span></p>
