Hi, I am dealing with a NAT situation related to mod_verto. The switch is hosted in EC2 and the configuration works great with mod_sofia (both for receiving calls from our SIP providers and via webRTC clients). However, the counterpart configuration for mod_verto fails to expose the external IP address in the SDP. Here's the mod_verto configuration we're using: http://pastebin.com/4PDMXvW6 I can confirm the external RTP IP is set properly, however here's the returned SDP: http://pastebin.com/3vzyihRp The verto client is running behind NAT as well, but this doesn't seem to be the root of the problem as Sofia's own implementation of webRTC works fine. It is effectively sending its media to 10.178.x.x rather than the switch's public IP address. Please advise, thank you. -- Best Regards, Ciprian Dosoftei The information transmitted is intended only for the addressee and may contain privileged and/or confidential material.
