| 10 | - Signaling works fine (E1 PRI, S0 BRI, routing between them) |
||
| 11 | - Voice calls work fine |
||
| 12 | - Data calls have the correct signaling, but *data corruption* |
||
| 13 | |||
| 14 | h3. Yate |
||
| 15 | |||
| 16 | - Signaling between 2 E1 PRI lines defaults to 3.1kHz audio, data bearer cap seems to get lost |
||
| 17 | - Voice calls work fine |
||
| 18 | - No native overlap dialing support (overlapped.php offers a workaround, questionable quality.) |
||
| 19 | |||

||
| 21 | |||
| 22 | - Trouble with bearer capabilities as well, needs patches |
