26 Call Control commands 6615-2220
The CLIR supplementary service subscription can be overridden for this call only.
“I” means “invocation” (restrict CLI presentation).
“i” means “suppression” (allow CLI presentation).
Control of CUG supplementary service information by “G” or “g” is allowed for this
call only. The index and info values set with the +CCUG command are used.
An outgoing call attempt could be refused if the AOC service is active and credit has
expired (NO CARRIER).
When trying to set up an outgoing call while there is an active call, the active call is first
put on hold, then the call set up is carried out.
GSM sequences
As per GSM 02.30, GSM sequences may be controlled using dial commands. These
sequences can contain “*”, “#”, but “;” is forbidden. If the sequence is not supported or
fails, +CME ERROR: <err> is returned. In the case where the FDN phonebook is acti-
vated, the sequences concerning call forwarding are allowed only if there are written in
the FDN.
Example of using GSM sequences:
