MSRP over Websockets - sr-users

24 Sep 2015


      Hi,
I am trying to configure MSRP over websocket and using Crocodilr-msrp
client for connecting the same but when I try to transfer any file it gives
me the below error.
Any thoughts is appreciated.
I am able to do audio, vedio and messaging using SIP-JSSIP client and
working fine.
Error - Log
