Webrtc via Expressway - No Audio/Video

[Ben Morgan]

Guys,

Hopefully a quick one for you.. Configure single CMS using webrtc via Expressway x8.11.

Internal works fine, as in join, audio/video.

External, I can log into the CMA client over the web, I can join a conference via webrtc..however I cannot transmit or receive audio/video.

I see STUN requests.. etc.. and binding allocation. Im running an ASA FW. The expressway-e has a single NIC..

The turnservers / status in CMS is telling me success and the private IP of the Expressway-E reachable.

The expressway-e TURN server stats are showing me hits and sessions..

I can connect in with an external SIP Client via the same expressways and can hear audio/video etc.

Any assistance would be appreciated.

Just to update. This issue relates to Firefox only. Chrome webrtc works fine. CMS version is 2.4

That's strange if it's firefox only - as far as I know, the network flow should be the same.  Are you behind a web proxy or anything that might have different settings between Chrome vs. Firefox?
