KAMAILIO tcp_send query, connection problem I have a KAMAILIO SIP server on a static IP from Comcast, using a modem/router Cisco DPC39412B.
I have a PC application server which is successfully signing on to the SIP server, via a LAN cable on the same network as the SIP server (Cisco).
In my second test, the PC application server is connected to the internet via a ZTE Falcon Z-917. In a third test, the PC application server is connected to the internet via a Talk-Talk fiber broadband. The connection does not occur.
From the log files, the successful connection says:

Any clues or tips would be greatly appreciated!

Hello,
opening the tcp connection failed due to timeout, indicating that no one was listening on the target address, which seems to be 172.56.8.182:44341 -- is any app listening at that address?
Cheers, Daniel
