[Spce-user] WebRTC <-> RTP: No audio on public host, works fine on local vagrant VM

Fri Mar 20 15:48:18 EDT 2015

Hello,  

I’ve been trying to connect a WebRTC agent to a traditional RTP soft phone, using mr3.7.2 as a bridge. Since then, I have also upgraded the rtpengine module to its current HEAD on github, which is roughly 3.8.0.0 to fix some other issues. The rest of the system runs 3.7.2.

My configuration is as follows:

Both subscribers are on the same domain (default NAT and media flow settings)

WebRTC subscriber:
— JsSIP on Chrome 41, with an RTP/SAVPF profile on the client.
— Media flow settings on the subscriber in Sipwise CE use rtpproxy as only ICE candidates
— SRTP transcoding: Prefer SRTP

RTP: Subscriber:
— Linphone, with an RTP/AVP media profile on the client
— Media flow settings on the subscriber in Sipwise CE use rtpproxy as only ICE candidates
— SRTP transcoding: Force RTP

Here’s the crux of my problem.

When running Sipwise CE mr3.7.2 from your vagrant box locally (both peers and the server running on the same dev host), calls work fine with this setup. But, when I try this same setup when running mr3.7.2 using your AWS image, calls establish successful signaling, but the audio is completely blank once the call starts out.

My hypothesis is that there is something wrong with ICE negotiation or NAT busting with my server setup, but I can’t quite figure out what.
Here are the pertinent records for each scenario.

Any help would be appreciated.

Local Vagrant, Sipwise 3.7.2 with compiled recompiled rtpengine 3.8.0. Successful call establishment, and 2-way audio.
