| LQROC | Retry for outgoing calls: The number of outgoing calls that were rejected by the network. For X.31 this includes retry for outgoing SETUP messages requesting a packet switched connection. For Q.932, retry for outgoing REGISTER messages are not included in this count. | PD (11,0) |
| LQTIC | Total incoming calls: The number of incoming call attempts. For X.31 this includes incoming SETUP messages requesting a packet switched connection. For Q.932, incoming REGISTER messages are not included in this count. | PD (11,0) |
