[asterisk-users] SIP over WSS connection : mask error

[Thava Iyer]

Hi,
I use chrome and sipml5  to connect to asterisk webrtc interface using TLS.
The wss connection seems ok and the SIP REGISTER sent from chrome to
asterisk and the SIP response received.
In the response, I get a "failed: A server must not mask any frames that it
sends to the client" error msg and chrome terminates the ws connection.
I've checked the asterisk debug logs,  and the wireshark tls trace ( after
decryption), the mask-bit of the WS Frame being not set. But the chrome
complains otherwise.

Given below is the chrome error log and the part of the wirehark capture
(after decryption).

Can someone , help me identify the problem?
