[SR-Users] xhttp module and IPv6

Fri Feb 20 21:49:53 CET 2015

Do you have event route for local replies generated via sl module?

The error log messages seems to come from a situation like that.

If yes, then perhaps is good to restrict the event route to sip replies
only, because the sip parser for http replies is not compatible always.

Otherwise, the websocket connection seems established, the http reply
goes to browser and sip register comes, so in this regard, the log
message shows a harmless situation.

Cheers,
Daniel
