My SmartNode can receive SIP via TCP but not send?
Posted by Danny Staub, Last modified by Daniel Lizaola on 20 December 2017 12:53 PM

By default, the SmartNode listens for both TCP and UDP traffic.  In order for the SmartNode to send SIP signaling using TCP, you will need to configure the following:

 

location-service SER_LYNC
  match-any-domain

  identity-group default

    call outbound
     preferred-transport-protocol tcp

    call inbound

context sip-gateway GW_SIP

  interface IF_GW_SIP
    bind interface eth0 context router port 5060

context sip-gateway GW_SIP
  bind location-service SER_LYNC
  no shutdown
