We have just purchased 25x Sangoma S505’s and they all have a very weird problem. The volume is super low on ringing and speakerphone. I think I can solve the ring problem by uploading some custom ringtones to the devices that have increased volume. But even at level 14 the speaker phone is so super low and if you are not within a foot or two of the phone forget hearing it. Does anyone have any suggestions other than returning the phones?
I appreciate any help we love the phones except for the volume issues.
