If the prefix to the forwarding command is "**" (instead of the usual "*"), then the phone number in that command is registered in the network. If after that the forwarding is deactivated using a command with a single "#", then later it will be possible to re-activate this forwarding again with a simple "*" command without a phone number in it. The forwarding will be re-activated to the number registered in the network. For example, if one uses the out-of-reach code in a forwarding command:
**62*7035551212#
and after that one deactivates the forwarding:
#62#
then later it will be possible to re-activate the out-of-reach forwarding without specifying a number:
*62#
After the above command, all calls made to the phone, while it is out of reach, will be forwarded to 7035551212. It is possible to activate the feature to a number other than the registered number, whilst still retaining the registered number for later use. For example, issuing the command:
*62*7185551212#
will result in calls being forwarded to 7185551212 (and not to the registered number 7035551212). However, if later a command is issued:
*62#
then the calls will again be forwarded to the registered number 7035551212 (and not to the number from the previous forwarding command 7185551212).
Additionally, in GSM networks, such as T-Mobile and AT&T Mobility in USA, and all mobile networks in EU, it is possible to set the number of seconds the phone will ring before forwarding. This is specified by inserting "*SC*XX" prior to the final "#" of the forwarding command, where "SC" is a service type code (11 for voice, 25 for data, 13 for fax), and "XX" is the number of seconds in increments of 5 seconds. If "SC" is omitted (just "**XX") then by default all service types will be forwarded. For example, forwarding on no-answer can be set with:
*61*[phone number]**[seconds]#
In some networks there may be a limit of not more than 30 seconds before forwarding (i.e. "XX" can only be 5, 10, 15, 20, 25 or 30; all greater values, like 45 and 60, will result in the forwarding command being rejected and an error message returned).
Uses[edit]
Diverting calls can increase one's availability to a caller. The main alternative is an answering machine or voicemail, but some callers do not wish to leave a recorded message, suspecting that the party will delay returning their messages. A caller at a telephone booth may be unable to receive the call if a recorded message is returned.
Some businesses find that the human touch can improve contact, thus sales, but traditional wired answering services are expensive, so they have their calls forwarded to a call center, so the client can reach an operator instead of an answering machine or voice mail.
Often, a suburb of a large city is a toll call from many suburban exchanges on the opposite side of the same city, even though all of these suburbs are a local call to the city centre. A business located in such a suburb may therefore benefit from obtaining a downtown number as an "extender", to be permanently forwarded to their geographic suburban number.
Where unlimited local calls are flat-rated and long-distance incurs high per-minute charges, the downtown number's wider local calling area represents a commercial advantage. Markham (directly north of Toronto) is long-distance to Mississauga (directly west of Toronto) . A Markham business with a forwarded area code 416 Toronto number could receive calls from Malton airport in Mississauga without incurring long-distance charges (as Malton → Toronto and Toronto → Markham are each a local call).
Some services offer international call forwarding by allocating for the customer a local virtual phone number which is forwarded to any other international destination. As a means to obtain an inbound number from another town or region for business use, call forwarding schemes tend to be far less expensive than foreign exchange lines but more costly than using voice over IP to obtain a local number in the chosen city.
