i have issues in the VoWLAN, i have an SSID and VLAN end to end only for Voice.
The issues is when im talking over the WLAN the voice goes the volume down and then up, when im roaming and when im static.
The PBX is BCM450 release 6.0
The phones im using is model 6120 y 2212 and a WLAN manager 2245 function as a proxy all the Wireless phone register in this wireles manager proxy.
I create roles, QoS and everything to work fine, but sometimes i notice the phones had disconected from the PBX and again it register back to the pbx
interface vlan 10
ip address 10.41.6.11 255.255.255.0
voip prioritization enable
voip rtcp-inactivity disable
voip sip-midcall-req-timeout disable
aaa profile "voz"
ap wired-ap-profile "HACIENDA"
switchport access vlan 10
wlan ssid-profile "HACIENDA"
essid "LA HACIENDA"
g-basic-rates 1 2 11 18 36 54
wlan virtual-ap "HACIENDA"
How can i troubleshoot this??
You need to turn on user debug to see what the phone is doing.
You also need to look at the Nortel Deployment guide for your phone. Depending on the phone, it will require ARM Min 12 and ARM max 18 TX power so that the AP's power matches that of the phone. In addition, a VOIP deployment will require more density than a regular data network (sometimes an AP every 50 feet) otherwise you will hear drops on the roams. You need to obtain the manufacturer's deployment instructions, because it is crucial..
what command is useful for the user debug?
1. Get a syslog server
2. Point the aruba controller to that syslog server (config t logging <ip address of sever)
3. turn on user debugging <config t logging level debug user-debug>
