π Network Port Settings for UsVox Hosted PBX Devices
Created by the UsVox Support Team
To ensure the proper function of UsVox Hosted PBX services, your network must allow specific ports and protocols used by SIP devices. The instructions below will help you configure your firewall or router for reliable call quality and connectivity.
π§ Before You Begin: Disable SIP ALG
SIP ALG (Application Layer Gateway) is a common feature on many routers and firewalls, but it often interferes with VoIP services.
β What to do:
- Disable SIP ALG on your router or firewall before opening any ports.
- If your device does not allow you to disable SIP ALG, we strongly recommend contacting your router/firewall vendorβs support team for help β they are trained to handle this.
π Required Ports and Protocols for UsVox Hosted PBX
| Port Range | Protocol | Usage |
|---|---|---|
| 5060 (UDP/TCP) | SIP | SIP Signaling |
| 5061 (TCP) | SIP TLS | Secure SIP Signaling |
| 35000β65000 (UDP) | RTP/SRTP | Voice Media Streams |
π‘ Network Access Rules
To allow full functionality for your SIP devices, configure your firewall or security appliance with the following:
- Allow all incoming and outgoing traffic (UDP, TCP) to and from these UsVox network blocks:
208.89.104.0/22199.180.220.0/22
- Allow inbound UDP traffic to all ports above
1024β these are used for RTP/SRTP media transmission.
