I am having periodic problems with a couple S505 phones being used by receptionists. About once or twice a week 2 of these phones develop static so bad they can’t be used and must be rebooted. Its been happening since we installed them a month or so ago but we waited to see if it would go away. Currently using firmware 1.58 but also happened on 1.57 Server is PBXact 1 18.104.22.168 Asterisk V. 13.27.1
Note: we have about 12 of these phones but most of them get used very rarely and ive had no other complaints but the reception phones get used all day.
Any ideas about what we can do about this. Thanks.
