Re: [SR-Users] Dispatcher BYE issue

Hi, I'm trying to achieve this configuration phone --> NAT --> kamailio loadbalancer --> kamailio sip/proxy --> kamailio sip/proxy With the attached configuration I can make calls without any problems but when the callee hangs up the call does not end only the caller can hang up. Btw I'm using tcp for signalling. Any ideas?
