[SR-Users] Error with ACK from SIPML5

Wed Sep 25 18:04:49 CEST 2013

I found out that when a subscriber has multiple contacts (ie. by stopping
and starting the WS client), kamailio either fails matching the connection
or matches the wrong one. Setting registrar max_contacts to 1 and using
save("location", "0x04") solved this problem for me.
