No. Wireshark or sngrep is fine for that. You need trace only from kamailio to verify that it sends proper SIP

Yuriy, really sorry for the dumb question, but to make it faster, is there a log I can get from kamailio/rtpengine or is it better to use something like wireshark?

Can you try to get SIP dump from kamailio to WebSocket endpoint on the kamailio machine?

I believe kamailio have no binary sip draft implementation on a board.

Yuriy, we get the whole invite message binary.

Are you talking about SDP part of the SIP invite?

Hi Yuriy,

yes, there is nothing between webrtc client SIP.js and kamailio/rtpengine. We have a sip server that sends a call to kamailio that forwards the call to webrtc client. Kamailio is running on plain linux debian EC2 AWS machine (no docker or anything else).

Some calls we get from kamailio in UTF-8 invite messages and other calls we get binary invite messages.

If logs or cfg helps, just let me know.

Thanks
Santos

SIP is a text protocol by default. Binary messages can be here only keepalive messages and etc. So it should not go to application layer of the client as it is a transport layer messages. Are you sure There is no other software between kamailio and client that creates a bridge between client and kamailio?

Hello guys,

we are new to kamailio so sorry basic or wrong points.

We started using kamailio 5.3.2 and rtpengine as our sip to webrtc solution and SIP.js as webrtc client. We noticed that most of the times webrtc client receives UTF-8 messages. But sometimes webrtc client receives binary messages. When we get binary messages SIP.js cannot parse the message.

I couldn't find how to force kamailio to send only UTF-8 messages. Is it possible?

We have other issues but I think it will be better for the list to break other points in different messages.

Thanks!
Santos
