Table
Log event | Description |
|
|
| |
[ch] Enable encoder <pt> | Voice encoder type pt is enabled for the channel ch, where pt can be 0 | |
| for | |
| For example, [0]Enable encoder 4 indicates that the Cisco ATA | |
| transmitted | |
|
| |
[ch] DPKT 1st: | The first voice packet that the Cisco ATA received was of RTP payload | |
<timestamp1> | type pt for the channel ch with timestamp of timestamp1, and the local | |
<timestamp2>, pt <pt> | decoding timestamp was set to timestamp2. | |
| For example, [0]DPKT 1st: 1491513359 1491512639, pt 4 indicates | |
| that the first RTP packet that the Cisco ATA received was | |
| ||
|
| |
[ch] codec: <pt1> => <pt2> | Voice codec switchover occurred. The voice encoder type switched from | |
| pt1 to pt2 for the channel ch. | |
| For example, | [0]codec: 4 => 0 indicates that the local voice encoder |
| on the Cisco | ATA switched from G.723.1 to |
|
| |
[ch] Rx MPT PT=<NSEpt> | Channel ch received an NSE packet of event with payload type of NSEpt. | |
NSE pkt <event> | For event, c0XXXXXX indicates a CED tone event, and c1XXXXXX | |
| indicates a phase reversal event. | |
| For example, [0]Rx MPT PT=100 NSE pkt c0000000 indicates that the | |
| Cisco ATA received a CED tone event NSE packet with payload type of | |
| 100. |
|
|
| |
[ch] Tx MPT PT=<pt> NSE | Channel ch transmitted an NSE packet of event with payload type of | |
pkt <event> | NSEpt. For event, c0XXXXXX indicates a CED tone event, and | |
| c1XXXXXX indicates a phase reversal event. | |
| For example, [0]Tx MPT PT=100 NSE pkt c0000000 indicates that the | |
| ATA transmitted a CED tone event NSE packet with payload type of | |
| 100. |

Debugging FAX Pass-through Mode
When the Cisco ATA is configured to use fax
Note For fax
Terminating-Gateway Example
When the Cisco ATA is used as a terminating gateway for a fax session, make sure the following conditions are true:
•The Cisco ATA transmits
•The encoder switchover to G.711 occurs during the
Cisco ATA 186 and Cisco ATA 188 Analog Telephone Adaptor Administrator’s Guide (SIP)
