Gammu can send SMS, but can't configure diverts
Hello,
I upgraded my OS from CentOS 6 to AlmaLinux 8 and since then, I'm unable to configure diverts with gammu.
I have a RS232 modem (do not know the model) and at the moment, a Huawei e3372. With both, I'm able to send SMS, get network info, but can't do diverts.
[root@server ~]# /usr/bin/gammu -c /etc/gammu-smsdrc canceldiverts
Unknown error.
I compiled the same gammu version as it was on the CentOS 6:
gammu-libs-1.42.0-1.el8.x86_64
gammu-1.42.0-1.el8.x86_64
Looking at the debug log, this is a part of it:

Gammu is sending AT+CCFC=4,4 which is a command to cancel all diverts, but it gets +CME ERROR: 171 back for which I can't find a usable description.
Anyone had similar problems and got a solution?
Hi, I'd suggest checking documentation of your modem, what's the CME 171 error, and the SIMcard itself, if it allows to cancel diverts (some SIMplans does not allow that).
This is interesting as the exact same modem and same sim card that is working on CentOS 6. The only difference is that I'm not using centos provided package but custom compiled as there is no pkg available for AL8.
I'm wondering if it can be kernel issue or some library. Will try to test on centos 7 just to see if it works there.
