Hi, I have audio problems when bridging calls from different sofia profiles. I use 2 profiles in order to connect softphone through a VPN to avoid NAT problem One profile is sending/listening on a private IP (for softphone) and the other profile is using a public IP (for external PSTN gateways) I have tested with X-lite and Ekiga and I face different one way audio with both: With X-lite the audio received from the private IP is not forwarded While with Ekiga the audio from the public IP profile is not forwarded I have traced SIP and RTP and the signaling looks good. RTP is received by FS on the correct socket but not forwarded. I understand I do not provide enough information to diagnostic, but maybe I could get input on how to diagnostic RTP socket etc. in this scenario ?
