I am using WTT HK Sip trunk which has a lan cable connected to our Cisco UC320W WAN port. All phones are connected to a switch connected to it. This lan does not have internet data.
These are the data from the vendor:
SIP Trunk IP: 10.xxx.145.241
SIP Server IP: 10.yyy.006.001
Gateway IP: 10.xxx.145.246
Mask: 10.xxx.145.240/29 (255.255.255.248)
I have FreePBX distro setup and I connect this SIP lan cable to office router and create a VLAN via System Admin module, and it never be online with. But when using Raspbx, same connection with manually add vlan like this, it can connect to the sip trunk:
auto eth0:1 allow-hotplug eth0:1 iface eth0:1 inet static address 10.xxx.145.241 netmask 255.255.255.248 gateway 10.xxx.145.246
So what is the problem? When using Raspbx, call will be dropped after 32 seconds.
So how to config FreePBX disto for this config? I can use different router or lan card if required.
I see other equipment vendor can connect this sip trunk. See this at hk-matrix. com/index.php/how-to-connect-wharf-tt-sip-trunk-with-sipdex-m200-ippbx/

I have been working with this for a month. Can anyone help? Thanks!
