[SR-Users] SIP over WebSockets error: bad request

[Brad Johns]

Hello Peter,

Thank you for the quick reply.  Yes, that did the trick.  Changing
"tcp_accept_no_cl" to value of no was the resolution.

It seems that the JsSIP Tryit sample code, which I was trying to hack,
doesn't use Content-Length in the header.  I wonder if this should be
changed to set the Content-Length in the HTTP header.

At any rate, thanks again.  I'm now registered, which is what I was looking
to do.

Brad
