| 41 | The MultiRate configuration string should contains the hex string from the |
| 42 | MultiRate configuration element from the Assignment Command message. |

| 46 | If "Voice boundary detection" is enabled, then only bursts are decoded as voice where |

| 48 | - the framenumber is greater then the framenumber of a received "Connect" or "Connect Acknowlegde" message, and |
| 49 | - the framenumber is less then the framenumber of a "Release" message |
