What is cpIwfIsdnBriPortB1FillerOctets?

This read-only Counter32 counts total PCM filler octets injected into the active media stream on the B1 channel due to playout buffer underflow. It flags jitter-buffer starvation specific to the B1 bearer channel of this ISDN port. If this rises on B1 but not B2, the admin can localize a voice-quality complaint on that ISDN line to the B1 channel specifically.
