WLC 9800-CL QoS Settings for 8440 Spectralink (VoWlan)

[f.duffy]

successfully setup WLC 9800-CL running 16.10 WLANs up and running, thanks to the built in config convertion tool.  

However are struggling to get the spectralink 8440 phone (VoWlan) properly running. I guess the QoS Settings were not converted properly.  

Phone authenticates (PSK, I know...)

gets its IP Address.

PhoneCall the Number can be dialled however receive error not enough bandwidth allocated. Where would I adjust that setting?

thanks for your help

as said

1. 8440 Phone authenticates to 4800 AP, which is 3 m distance to the phone, line of sight :-)

2. 8440 Phone authenticates

3. Phone gets an IP

4. Phone starts to dial however we can't hear the ringing tone.

5. Phone jumps onto the current running system with wlc 8510. And error on the spectralink phones is not enough bandwidth allocated. 

Thank you for your support

Solution:

disable CAC on the wlc and on the spectralink phone, and VoWlan works hust fine with the above config
