[SR-Users] Error with ACK from SIPML5

Wed Sep 25 12:01:22 CEST 2013

I am getting this error when trying to call from an ip phone -> kamailio ->
freeswitch -> kamailio -> jssip. It looks like it can't match the invited
subscriber to a WS connection. Calls from jssip to ip phone works (although
it hangs up after 3-4 seconds for some reason).
