The laptops on the network are generally fine.
The only thing missing from that guide is using Spectralink in the EDCA profile
Things that will cause voice to suffer
- Co - Adjacent channel interference
- non 802.11 Interference
- Improper configuration
- QoS not config properly
- Security posture overhead (in some cases)
- Firmware concerns (handset / controllers)
Not having a good analyzer it is hard to really say, cause you cant see what is going on.
I have limited exposure to S-link, as i live on the Cisco, Ascom, Vocera side. Does s-link have any untilities built into the handset to determine what the 'phone' is seeing? If so that would be a good start, perhaps retry counter?
