Hello
I have a call with not passed ACK by Kamailio. http://prntscr.com/jhtobo
Same behaviour i looked before when SIP endpoint contact string is wrong
In this call look as contact string correct is correct (packets 7 and 8)
and i not understand why ACK (packet 9) not passed to callee.
Could you help me understand this.
PCAP file is create using homer tracer and TCP transport packets is stored
as UDP.
