OK, please tell me that I am not going crazy! I have two S705 phones with an expansion unit for the main office of a school. After about 3-4 days of use, all of the audio (ringing, earpiece, microphone) becomes extremely choppy and unusable. The secretary described it as a low signal cell phone call. Here are the steps I have taken so far:
- Replaced patch cables
- Moved to a new drop
- Upgraded firmware (184.108.40.206 for the phone, 220.127.116.11 for the EXP100)
- Installed system and module updates in PBXAct
All phones on that floor used the same switch with a dedicated fiber uplink. All of the S505 phones do not exhibit this behavior. In addition, another school client with the exact same S705 phones do not have this issue.
Is there anything else I can check? Restarting the phones resolves the issue for another few days.
