[OpenSIPS-Users] Cause of tcp_receive_timeout

[Hamid Hashmi]

I am trying to load test TLS listener through sipp.  REGISTER Request is working on TLS but INVITE is not working. I changed the transport to TCP and receive following logs

PCAP file is also attached.

SIPP Caller 192.168.3.60 ------- > SIP Server 192.168.3.19

TLS connection working fine with the softphone. This only occurs when I send TLS/TCP request through SIPp script.
