Hi all,
We are having some diffuclties getting our virtual multitenant 3CX install working.
I followed this guide:
http://www.3cx.com/docs/virtual-pbx-firewall-setup/
https://doc.pfsense.org/index.php/PBX_VoIP_NAT_How-to
Our Setup:
A Pfsense 2.3-1 that has the PPOE session
Transit VLAN
a pfsense connected to the transit vlan
each pfsense that is connected has a virtual external static ip. With a 1:1 NAT mapping.
so I'll try to give an example:
1.1.1.1 --> 192.168.1.1 pfsense 1
192.168.1.2 --> 192.168.0.1 pfsense 2 (has 2.2.2.2 as Virtual IP - NAT mapping)
192.168.0.100 --> 3CX
3CX instance 9 (yeah somehow this is the first? )
Sip port: 13060
Sip Tunnel: 13090
Now the problem:
Every phonecall got disconnected after 32 seconds.
A second try:
I moved the 3CX into the transit VLAN.
1.1.1.1 --> 192.168.1.1 pfsense 1
192.168.1.100 --> 3CX (has 2.2.2.2 as Virtual IP - NAT mapping)
The problem with this is:
The phonecall keeps connected now, but I have no sound.
Logs keep telling me:
31-mei-2016 14:03:30.506 NAT/ALG check:L:5.1[Extn] REQUEST 'INVITE' - some of SIP/SDP headers may contain inconsistent information or modified by intermediate hop
SIP contact header is not equal to the SIP packet source(IPort):
Contact address:192.168.1.2:37587
Received from :192.168.1.2:57977
'audio' media IP is not equal to the IP specified in contact header:
'audio' media IP is not equal to the SIP packet source(IPort):
So obviously I am doing something wrong.
I just don't know what. I checked over and over for settings.
Need more info? Please ask!
