MS Power Transmit not changing

Hello Neels and Community, Good day! We are doing some testing on our Lab specifically in Voice. During this testing we observed that the MS power transmit is not changing during ongoing call and the value is 5dbm. We also do walk test in order to lower the received power level and to observed if the MS Transmit power will increase. We tried to change some parameters in osmo-bts-trx uplink-power-target but however, the MS Transmit power still the same which is 5dbm. The MS power in the osmo-nitb config is set to 23dbm. Below is the version and configuration we used on our testing in Lab. Version: OpenBSC# show version OpenBSC 1.3.2.2-d2550 (OpenBSC).
