    Hello Folks,
    I believe it is easy question but I don't know how need to resolve it.
    I have device which can work over TCP 5060 only. But my 3CX (7) connects to line over UDP.

    20:53:07.288050 IP sip.5060 > dsenvm.5060: UDP, length 800
    20:53:07.288082 IP dsenvm > sip: icmp 556: dsenvm udp port 5060 unreachable

    The main magic thing is that intermittently 3CX tries to connect over TCP but intermittently only. One of 3-4 times.
    It is not acceptable. How can I configure the connection over TCP 5060 only?

    Cheer, Dsenash
