Hi friends, we have an old version of WCS (5.0.2570) that is causing a lot of problems with webrtc/sip voice traffic (mainly from android app to external SIP servers). It stops working and we have to restart the WCS almost everyday, and some days even more times. We are testing now in other server the lastest version of WCS (5.2.458) but when we make a call from the DEMO web to a mobile, the handset rings and you can answer the call,but ince you answer it, ther is no audio and the call is hangup. I've copied exactly the same config that we have in the old version in other server where it works fine. Including codecs, firewall, etc. I attach the log of the server. BR and thanks in advance.
