[Spce-user] Setting advertised-ip breaks calls for internal network (vlans)

[B Davis]

I have setup the network as shown below.

All of the ‘PBX’ systems on the internal LAN (VLANS) are routed traffic (no nat being performed by the firewall)
Internal LAN resolves the domain sip.services.com <http://sip.services.com/> to the internal IP of the SIPwise server to avoid firewall 
hair-pinning. 

If we do not set adverse-ip then internal PBX, can make outbound calls just fine.
However external PBX’s can not. 

Setting the advertise-ip allows external PBX systems to operate correctly but breaks calls for internal LAN (VLAN).


The Sipwise server is operating as a VM. It has 1 Nic eth0.
The firewall (pfSense) performs a 1:1 NAS from the public IP address to the SIPwise server.

What I think is happening here is that when advertise-ip is set, it is treating the calls on the internal VLAN as remote
connections and attempting to handle ‘NAT’ on them. 

Is there a way to instruct sip wise/kamailio to *NOT* apply the advertised-ip for specific networks (e.g. my vlans)?

Thank you,
