GDMS specifies the PCode of 823 when you set it to configure the A/C 6 Ring Tone for a GXP2170. Is should be 1823.
Thank you for using GDMS platform! The P1823 and P823 points to the same configuration in GXP2170, and it will not affect users to use the provisioning feature. This is indeed a known issue, and we have passed it to our developers for evaluation. Thanks for your testing!
