Update: We integrated pjsip with WebRTC on iOS, we are using pjsip for the signalling part and passing the SDP back and forth to and from WebRTC. Our current issue is that after initializing the call we can't hear any audio (should hear moh at this point), everything looks OK on Freeswitch until we start seeing alot of those errors: 2015-01-16 20:25:31.111260 [ERR] mod_opus.c:418 Decoder Error: corrupted stream fs:4080 plc:0! 2015-01-16 20:25:31.111260 [ERR] switch_core_io.c:697 Codec RAW Signed Linear (16 bit) decoder error! [9] Any idea what might be wrong here? Thanks, Adam On 15 January 2015 at 15:27, Adam Ben-Ayoun <adam.ben.ayoun1@gmail.com> wrote:
In our case, all clients are calling to the conference on FreeSwitch, hence, no registration is required at the moment, but it definitely opens up other options for future.

Great to hear that. Thanks again.

WebRTC doesn't specify a signalling protocol. This means that you can use SIP over any transport you want to carry the webRTC enabled SDP.
FS will receive the SDP, detect that has a RTP/SAVPF profile and start handling it accordingly.
Take for example Jitsi or IMSDroid, they both support webRTC and do SIP over UDP/TCP/TLS.

Thanks Anthony. I assume that means I can use SIP over TCP/TLS for signalling? Also, will mandatory WebRTC requirements such as DTLS-SRTP work when communicating with FS (when stuff like fingerprint, etc)?

The WebRTC media engine is driven completely by the SDP, the transport will not make any difference.

Hi,
We are developing a mobile client that will use the WebRTC media stack and Freeswitch as an MCU (only for conference calls). My question is, since we build a native app, can we use SIP over TCP for signalling? In other words, if Freeswitch receives the WebRTC kind of SDP, will it be able to communicate in the same way as if we were using the SIP over Websocket (the other Freeswitch option)? Any corner cases/considerations with this? Our goal is to avoid implementing SIP over Websocket on the client as much as possible.
Thanks, Adam
