Motorola first phone and next gen first phone troubleshooting requirement guidelines:-
#Below guidelines can be used as part of data collection to troubleshoot unknown/hard engineering issues in 3rd party voice client on Cisco infrastructure(CA/CUWN).
#Refer the motorola phone code certified by cisco's infrastructure through assurewave program.

#WLC and AP's switch port config.
#802.1p config on WLC.
#CAC config on WLC.
#AP model used.
Voice Handset config details:-
#Supported roaming - 11r, 11k, 11w.
#Are DTPC supported/enabled.
#Channel scan mechanism used - All/country/configured.
#RSSI cutoff to roam on same and different band - Roaming aggressiveness configured.
#power save mechanism used/supported.
#power save mode aggressiveness – low/med/high.
#What’s the key-caching mechanism used/supported OKC/PKC.
#Are Cisco’s Aironet IE and cckm supported.
#Voice codec used.
#wmm status on phone.

#Selected country code?
#Phone Transmit power or TPC - low/med/high – auto/manual.
#Phone Antenna gain and polarization.
#Voice client on band - 11a/g, 11n, 11ac.
Validate RF environment:-
#Attach store/site map and layout, if available. Attach google map, if outside the building.
#Global TPC config on 2.4 and 5ghz.
#Total no. of rogues, if over 100 then check channel utilization on 2.4ghz.
#Attach high channel utilization report from prime, if possible.
#Attach non 802.11 interference device reported on 2.4ghz, applicable when clean-air capable AP is used otherwise use external spectrum expert card.
#Multiple iteration of show client detail from affected location. Parse and map for AP-name, channel no, Respective channel's utilization, RSSI and SnR.
#Attach prime heatmap for the respective or both 2.4 and 5ghz bands, if possible.
#Attach AP visual inspection report from the affected spots.
#Airmagnet survey report or any survey report that shows the existing RF coverage of site from both bands.
Troubleshooting:-
#Show run-config of WLC.
#Attach network topology.#Eliminate individual handset issue.
#Verify correct number of APs are connected to controller.
#If high channel utilization witnessed on 2.4ghz then move to 5ghz band.
#Attach debug client from WLC and AP debugs while reproducing the issue.
#obtain Wired and Wireless pcap.
Leverage Troubleshoot capability on the phone:-
#How to place the phone on site-survey mode.
#How to place the phone on diag-mode OR collect voice stats or metrics.
#Are any built-in phone-log or debugs available, if so how to enable and make use of them.
