Firewall port settings for hardware

Since the TELUS Business Connect solution is a cloud-based phone system, it streams through an Internet service. When setting your hardware (desk phone) to the solution, you might encounter some situations when your firewall, router, or other Internet appliance may block connections. We recommend you open the following ports to ensure your hardware can communicate with the servers:

Device type Protocol Source port customer side Destination port TELUS Business Connect side

Deskphone signaling SIP/TCP 5060-6000 5060

Deskphones signaling Secure Voice SIP/TLS/TCP 5060-6000 5096
