According to the sip config file:
# Indicate if the server is behind NAT. If so, the server will use STUN
# to guess its own public IP address and use it in the Contact header of
# outgoing requests
behind_nat = true
We find that the contact header in the SIP INVITE uses the local address of the Janus server not the public address determined from STUN. Are we doing this wrong? How can we get Janus to insert the public address in the contact header.
