Static on S505 Phones

(Shackbill) #1

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 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.

I’ve gotten complaints of static from our operators (S505) from time to time… replacing the cord going from the phone to the handset has resolved it. The problem has not yet recurred after replacing the cords that came with the Sagoma brand phones.

Thanks much for your reply. That would be great if that ends up being the fix because my client is complaining they don’t like the cords anyway and want something that doesn’t tangle so easily. I will look for a a higher quality cord and try that. Thanks again.

Still getting static periodically from the Reception phones where i replaced cords. Any ideas on Phone settings or a log that can be checked to troubleshoot this? Thanks.

In addition to the cord problem, the phones can ‘static’ during screen updates. There are new firmware versions that we supposed to take care of this.


I’m not certain that this is a firmware related issue, but making sure you’re on the latest available to your system is a good idea to rule out some things like Dave mentioned. Is the 1.58 Endpoint Manager firmware package the latest available on your system? Make sure you’re on the latest version of the Endpoint Manager module from the Module Admin page to make sure you have the latest set of approved firmware.

During the times when there’s static, do you notice any other behavior issues? Like, screens that respond slowly when getting a call or pressing keys. Also, can you tell us more about the receptionist phone setups? Are there expansion modules in use? How many BLF keys are in use? It doesn’t sound like a hardware issue if it’s happening for multiple receptionists, but it could be helpful to rule that out by switching some receptionist phones with people that don’t have the problem, and verify the problem still occurs with the receptionist, and doesn’t repeat with the replaced user.

Thought we had the latest but just checked and noticed there is a new system and phone FW available. we will get downtime tonight and conduct the upgrade and post our results here after we have a chance to evaluate the issue. thanks.
