             Summary: When T.140 realtime text is negociated, a lot of debug traces are generated
                 Key: ASTERISK-28002
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-28002
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_rtp_asterisk
    Affects Versions: 13.22.0
         Environment: Cent OS 7 - 
            Reporter: Emmanuel BUU
            Severity: Minor


If we process a call with T.140/RED and activate debug traces

core set debug 1

We get a constant flow of traces:

Received frame with no data for RTP instance 'xxxx' so dropping frame

We propose the follwing simple fix in res_rtp_asterisk.c

In :

static int red_write(const void *data)
{
        struct ast_rtp_instance *instance = (struct ast_rtp_instance*) data;
        struct ast_rtp *rtp = ast_rtp_instance_get_data(instance);

        ao2_lock(instance);
        ast_rtp_write(instance, &rtp->red->t140);
        ao2_unlock(instance);

        return 1;
}

Correct the line

if (rtp->red->t140.datalen > 0) {
     ast_rtp_write(instance, &rtp->red->t140);
}
