I need to delete entry in missed calls list.

1) I choose missed calls phonebook (AT+CPBS=MC).
Answer is: OK
2) Then read entries with AT+CPBR=1,10.
Answer is: +CPBR: 1,"+abcdefghij",145,""
3) Finaly try to delete this entry with AT+CPBW=1. But MC phonebook is
read only and I am not phone replies ERROR.

I think it is (or should be) possible to delete missed calls.

Any advice?

Phone: Siemens TC35

The relevant technical standard, GSM 07.07, states that for the
"MC" phonebook, "+CPBW may not be applicable for this storage".
Furthermore, the Siemens TC35 "AT Command Set" manual clearly
states "+CPBW not applicable to [MC] storage".

There doesn't seem to be any other mechanism to selectively erase
"MC" storage. This makes sense, given the dynamic (and therefore
temporary) nature of the numbering of the entries. I can only
suggest that a power down / power up cycle might clear it.

For my application I need to have only new missed calls in this phonebook.
After reading them I need to delete whole phonebook. I could reset all
phonebooks (I don't use them) but I don't know how to do that.

Turn off for a few seconds is not enough. MC phonebook is semi-permanent (or
something such)... On the other hand I need to do that only from my PC
remotely.

I have tried reseting Siemens via AT+CFUN=1,1 and this is not enough and
consumes a lot of time.

Any other advices? I don't know how to continue...

Perhaps there's a different approach that would work. Instead of
relying on the "MC" phonebook, have you considered logging (via
AT commands) the CLI of each new call as it arrives?

Thanks a much.
I have solved this with AT+CLCC and AT+CHUP.

OK. But I was thinking more of using "AT+CLIP=1" to read the
calling number (the command is used once, and each new call then
displays the number).

Used in conjunction with "AT+CRC=1", this will give you the call
type too. I was too lazy earlier to refresh my memory of these
commands. The following example shows their effect on my Siemens
S55, and your terminal should behave the same.

at+clip=1
OK

RING

+CLIP: "02nnnn",129,,,,0
at+crc=1
OK

+CRING: VOICE

+CLIP: "02nnnn",129,,,,0

(where "nnnn" replaces my home phone number).
