Combine multiple networks into a single network by configuring routing rules or using network aggregation tools.

He has multiple shop locations and needs IP phones that can connect across branches. A virtual LAN might help create a unified network feel. Each branch likely requires its own router to manage the local connection. A SIP account is used for calling services, so having multiple accounts could be relevant depending on usage. Some phones support different SIP profiles (2.4, 4, 6), and a PBX may be useful for managing calls. Let me know if you need further clarification.
I’d really consider hiring a solid consultant firm that can address your concerns and deliver thorough assessments and guidance, along with assistance when challenges arise. This goes beyond typical casual forum discussions and probably demands ongoing design and maintenance efforts, even for straightforward needs.
As mentioned earlier, I wouldn’t promote your offerings to businesses if they haven’t actually provided the service before. Picture hiring a mechanic to repair your vehicle without prior experience, only to discover they’re just asking questions online in search of answers. Growth matters, and you need a solid foundation… but I’d prefer to work with a consultant who can ensure quality and help you develop skills. Relying solely on paid internet research isn’t the right approach.
A VPN might work, but linking all networks together could be excessive. It’s probably better to focus on connecting only the necessary systems for VoIP within a single network. Centralizing the PBX with all branch phones would simplify management. Every device would use a SIP account, and calls would route automatically based on location. A VPN would introduce delays, instability, and extra setup challenges at each location.
Determine whether you need a single device or several units. For one, choose a router supporting VLANs and a switch that allows VLAN configuration. If multiple sites exist, deploy routers per location and establish an IPSec tunnel between them. Treat SIP accounts like extensions—multiple ones on one device are possible. Consider 3CX options; you may self-host or use a hosted solution. No VLANs needed unless isolating subnets is required. Licensing costs scale with extensions and concurrent calls. You might set up a hosted 3CX instance, place a SBC at each site, and have phones connect via the SBC. At work we do this. If self-hosting, you can use Direct SIP-STUN provisioning without a dedicated SBC per site—just supply the MAC address. Recommend using Yealink phones; then acquire or port numbers to a SIP provider such as Flowroute, directing traffic to your 3CX instance. If self-hosted, assign a static WAN IP to your PBX. Through 3CX, they’ll provide one. A PBX is essential—ideally a 3CX appliance. Grandstream offers some but I prefer alternatives. I’m happy to assist with any 3CX questions.
