Editing Call forwarding (section)

===Forwarding delay===
In GSM networks of some US carriers, and in all mobile networks in Europe, it is possible to set a number of seconds for the phone to ring before forwarding the call. 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:

<code>*61*[phone number]**[seconds]#</code>

Forwarding voice calls only can be set with:

<code>*61*[phone number]*11*[seconds]#</code>

In some networks there may be a limit of not more than thirty seconds before forwarding (i.e. “''XX''” can only be 05, 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).
