Hi all,
We have installed 3300 ICP CX 7.0.9.5 with 6 analogue trunk lines.
When making internal calls there is no echo. But when talking IP Phone to an external line, there is echo for 10 or 25 seconds. After this time period, it stops. The telecom lines are fine when checked with direct analogue phone connection. We have tested default configuration...
Meanwhile, We tried to test the CX analog trunks. We did LMS and set up the PBX according to its results. But after two days, the trunks are again starting to produce echo.
Have You Any idea?
Best Regards...
