Have a perfectly fine running setup with 4 analog trunks. All remote extensions can connect to the PBX and everything works fine. Network is set to Switch Mode where LAN 1 of PBX is connected to a router (192.168.1.0 Subnet) with internet uplink.
Now we have got a new Multiline SIP connection from the same ISP. The problem is they have brought in a separate fiber line for this terminated to a ONU , which is further connected to a Tplink router (i think for bridging the VLAN on port 3) as the ISP asked us to connect the IP PBX to LAN 3 of this router.
My question is would it be possible to connect this SIP trunk along with my existing Internet connection using DUAL mode (LAN 1 to existing internet connection & LAN 2 to the new Multi Line SIP connection) and would my remote extensions work in this setup…how should i go about it
Any help will be highly appreciated…
