Good day... I am interested in any experiences ppl have had with UC500 installations and FXO Volume issues. We have installed at least 5 UC540's and 560's that have had issues with Volume. The customer has complained that the volume is too low. We have tweaked the volumes so much that we end up having white noise issues.
This seems to only affect UC500s, we have not seen the issue on any CME's (which we have also installed). In addition, we have not had the issue in UC560's where we used a PRI.
Has anybody else experienced this? Were you able to find a solution?
