I have Wireless LAN (WLAN) which comprises of PCs and IP wireless phones.
Infact, I have six Cisco Aironet 1200 series Access points. one per each room and Avaya Voice Priority Processor which prioritises voice traffic on the WLAN.
There are only three wireless IP phones and 3 PCs per room.
The voice quality is good when two users are on phone. however, the quality becomes very bad when the third user is also on phone.
Any ideas on why quality becomes very bad when the third user is also on phone.
Also what can be done to rectify the voice quality problem.
