comment Are VLANs necessary for my environment?
Actually a separate network for management is a must on most business networks to prevent inside attacks on equipment. Setting up a port for management only is easy and imho strongly recommend

comment SIP INVITE packet has WAN address rather than call manager LAN IP
On the call server side there is a Zyxel router, on the local side (where the 2 phones are) is a Mikrotik. A IPSEC VPN tunnel is between both. The techs insist the Zyxel does not have NAT or SIP ALG (the Mikrotik definitely has disabled SIP ALG and NAT) - would the trace indicate the Zyxek is changing packets and not the Mikrotik?
