I may having something setup wrong but I cannot put my finger on it. I have an Asterisk system (13.22.0 ) running behind an SBC so remote users can register their phones through the SBC to the phone system.
Users running PJSIP with their phones connected to the PBX directly are ok with audio.
Users running PJSIP through the SBC are having one way audio issues on outbound calls. Inbound calls are ok.
For example, extension 500 dials *98. No audio. But if extension 501 dials 500, no audio issues. Let me know what other info I need to provide to help further look into this issue.
