Call Control Options..some things we will come to see here in St. Louis.
|
|
|
|
Call Return: by pressing *69, (1169 on rotary dials), customers can
|
|
return the last local incoming call. This service means fewer mad dashes
|
|
from the shower to answer a ringing phone before the caller hangs up.
|
|
|
|
Call Cue: By pressing *66, (1166 on rotary dials), customers can
|
|
avoid getting repeated busy signals. Busy local numbers are redialed as many
|
|
times as it takes to get an answer, for as long as 30 minutes. A special
|
|
ring is the cue when the line is free. Call Cure allows customer to perform
|
|
other activities while their phone monitors their line for them.
|
|
|
|
Priority Call: By pressing *61 (1161 on rotary dials), customers can
|
|
confidently answer--or ignore--their ringing phones. A special ring tells
|
|
them when a call they want is coming through. (Three local number can be
|
|
designated as priority.) Less importatn calls can wait for a better time.
|
|
|
|
Call Blocker: By pressing *60 (1160 on rotary dials), customers can
|
|
avoid inconvenient--and even unwelcome--calls. As many as three local
|
|
numbers can be blocked at any given time (except in Missouri, where six
|
|
numbers can be blocked).
|
|
|
|
Call Trace: By pressing *57 (1157 on rotary dials), customers can
|
|
gain a new defense against harrassing calls. That stepinitiates a race of
|
|
most local calls and customers may request that the calling number, date and
|
|
time be given to law enforcement officials for further investigation.
|
|
|
|
Selective Call Forwarding: (Only available in selected Oklahoma
|
|
exchanges.) By pressing *63, (1163 on rotary dials), up to three numbers can
|
|
be selected for forwarding to another telephone number. Only these calls
|
|
will get through to the designated number.
|
|
|
|
These services where first offered in cities that had single central
|
|
offices. Call Control Options are going to be introduced into Southwestern
|
|
Bell's 12 major metropoliatian areas as soon as possible.
|
|
The technology that enables SWBT to offer CCOs is known as Signaling
|
|
System 7 (SS7). Special SS7 software lets central offices "talk" to
|
|
each other. The central offices become part of an intelligent network that
|
|
sets up a signaling path.
