Version of smsd: 3.0.10
Smsd installed from: sources
Name and model of a modem / phone: Siemens MC35
Interface: serial
It happens very rarely.
some of sms are sent ( received by recipient ) multiple times , e.g. 15 or 89 .
smsd has no issues in its log ( loglevel =5 ). In the log there is only one record for each sms sent.
All cases are with sending to another country. However there are a lot of other messages to the country with no issues.
Keke , or someone else , could you please advice with the issue ?
