Interconnection with SIP Server

[JRed]

Hi,

Our initial idea to connect JsSIP WebRTC client to a SIP Server / IMS  was using Asterisk. However, our understanding is Asterisk would not forward SIP REGISTER to the SIP Server, which would complicate authentication and security. We have found references to using Kamailio  as WebRTC - SIP GW + rtpengine for RTP, which seems a sound alternative. Can anybody indicate if this mixes well with JsSIP and is something you can recommend ?

Thank you
