Worked on enhancing the Kamailio repository by improving the clarity of RTP Engine URI semantics within user-facing documentation. Focused on updating the rtpengine module’s documentation to specify that the rtp_inst_pvar variable stores the selected RTP Engine URI rather than the IP address, directly addressing a common source of user confusion during configuration and onboarding. Utilized XML for documentation updates and applied technical writing skills to ensure the information was accessible and precise. The work delivered a targeted documentation feature, reflecting a focused approach to reducing ambiguity for users interacting with RTP Engine configuration in Kamailio during the specified period.
