PLS Help Me
Tanks :wink:

  1. add an/ip firewall address (sip server)
    2./ip firewall mangle
    add action = mark-connection chain = prerouting disabled = no dst-port = 5060
    new-connection-make = voip_conn = yes protocol = udp passthrough command
    add action = mark-connection chain = prerouting disabled = no dst-port = 5061
    new-connection-make = voip_conn = yes protocol = udp passthrough command
    add action = mark-packet chain = prerouting-mark = \ voip_conn disabled = no
    new-packet-mark = voip passthrough command = no
  2. service-port set/ip firewall sip disabled = yes ports 5060, 5061 sip = direct-media = yes
    4./firewall filter add action = accept chain = forward comment = sip disabled = no dst-address-list = sip
    src-address-list = sip
