Phonebook entries in MC storage cant be deleted in some of my modems.

at+cpbs="MC" OK at+cmee=1 OK at+cpbw=1 +CME ERROR: 3

smstools logs:

2021-08-31 15:51:38,6, XRUSB325: Removing processed phonecall entries (2) 2021-08-31 15:51:38,7, XRUSB325: -> AT+CPBW=2 2021-08-31 15:51:38,7, XRUSB325: Command is sent, waiting for the answer. (5) 2021-08-31 15:51:38,7, XRUSB325: <- ERROR 2021-08-31 15:51:38,4, XRUSB325: Ignoring phonecalls, too many errors

Every time smstools gets restarted I get same events again. Like in this post it would be possible do accept CME ERROR when trying to deleted an entry. But that would not solve our problem. I think events would be fired repeated every time PB gets read.

Docs about m39i says: "In the”MC”, ”RC” and ”LD” phonebooks, automatic deletion of the entries stored in ME will be performed if the SIM card is changed. If the same SIM is removed and reinserted, no automatic deletion
is performed. "

Is there any possibility to avoid these duplicates? Maybe read a timestamp of the missed call?

Or maybe only fire event when RING comes in? This would be a great solution to avoid PB usage and receive incoming call events in real time.

Thanks in advance.
