Hello All, I have an issue where Kamailio-RTPEngine-Asterisk calls work good when a softphone UAC on an IOS phone makes an Inbound call to a WebRTC client. However, if the softphone UAC is on Windows, it does not work (No Audio/Video). I noticed in the Wireshark trace that when using IOS I see STUN packets, but when using Windows I see no STUN packets. I believe this may be my issue, but I am not sure why the IOS would create STUN packets but when using Windows I get no STUN packets. Does anyone have any thoughts on what could be causing this? Thank you,
