I have CP-7920 Wireless IP-Phones connected to an Access-Point 1200. The Problem is during a call the called party hears a continous background hissing noise. I found nothing how to turn this off. The wireless connection in principle is regarding to signal quality ok. The 7920 is running the latest Firmware 7920-sccp.1-0-6 and the AP 1200 is running the latest IOS 122-13.JA1. I´ve as well configured QoS on the WLAN.
I have done a simple test to verify if this issue was due to this bug. But simply when you call an other IP Phone (7960) from the 7920 IP Phone, there is a background noise heared on the 2 IP Phones (7960 & 7920) during the conversation.
