             Summary: Incoming UCS2 encoded SMS truncated if SMS length exceeds 50 (roughly) national symbols
                 Key: ASTERISK-24468
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-24468
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Addons/chan_mobile
         Environment: All
            Reporter: Dmitriy Bubnov
            Severity: Critical


One symbol in national language expanded to 4 bytes when UCS2 character encoding used.

So, size of 256 bytes for receiving buffer {{buf}} in function {{do_monitor_phone}} is not enough for incoming UCS2 encoded SMS, which is longer than 50 national symbols. I suggest just make this buffer 4 times bigger, namely 1024 bytes, instead of current 256 bytes.

Such modification will make incoming SMS in UCS2 encoding to not be truncated. Provided patch reclaims truncation only for incoming SMS, and not affect outgoing SMS.
