Hello!
Been banging my head on this one for a couple of days. I am quite well versed in the technologies being used here so this is my senario, and I am hoping for some assistance as per the title.
Any suggestions here would be apprecated!

- 3CX Debian based appliance installed in VMWare
- Everything works perfectly with the exeption the PBX will not accept any inbound SIP calls.
- Using on prem as the customer has a large number of legacy SPA504G phones that will only register on a LAN.
- Microtik Rb2011 with latest firmware and respective NAT rules in place.
- All firewall tests in 3CX pass fine.
- Tested SIP trunk against one of our VPS based instances and works fine.
- Outbound calls from the on prem instance works.
- Softphones register fine.
- can make extn to extn calls OK.
- Have flushed and disabled iptables :
iptables -X
iptables -t nat -F
iptables -t nat -X
iptables -t mangle -F
iptables -t mangle -X
iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT
iptables -t nat -F
iptables -t nat -X
iptables -t mangle -F
iptables -t mangle -X
iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT
- Firewall rules work. Tested using Hercules to confirm ports accepting traffic on port 5060 etc.
- SIP ALG disabled.
- Whitelisted the ITSP IP address in the "Blacklist IP Addresses"
- Pro Licence applied.
- configured with FQDN and SSL, all working perfectly from the outside world.
Any suggestions here would be apprecated!
