    With the SIP protocol we didn’t make any change, because it worked as expected, unlike PJSIP, that was need to change a specific parameter to work.

    The PJSIP parameter is named “RTP Symmetric (rtp_symmetric)”, this parameter allows you to configure the PJSIP protocol to send the RTP packages back to the same address/port were was received it from.

    You can change this parameter in the Technology Profiles module(Settings >> Technology Settings >> Profiles). You must set this parameter to Yes.

    About PJSIP Settings module, we have determinate that there are some issues that we must to fix, however, this issues doesn’t affect the PJSIP calls, except if is behind nat, due there are some settings that is no possible to save trought this module.
