Review the firewall and network requirements required to allow the net2phone Canada system, devices, and provisioning services to communicate properly. If these ports and IP ranges are blocked, phones may fail to register, calls may fail, or audio issues such as one-way audio may occur.

Most networks do not require firewall changes

The net2phone Canada Sync service has been engineered to work in most environments without requiring changes to firewalls or other network components. This guide contains information that may help optimize the network for net2phone Canada’s Hosted PBX service.


Required protocols and ports

Ensure the following protocols and ports are allowed on your network for proper functionality.

Service Protocol Ports Direction Purpose
SIP TCP/UDP 5060, 6070 Outbound Call signaling
TLS TCP 5061, 6071 Outbound Encrypted call signaling
WebRTC TCP 443 Outbound Browser-based calling
RTP UDP 10000-40000 Outbound Voice audio
HTTP TCP 80 Outbound App and provisioning connectivity
HTTPS TCP 443 Outbound Secure app and provisioning connectivity

Allow net2phone IP range

Allow the ports above for the following net2phone Canada IP range: 207.202.0.0/18


Disable SIP ALG on SIP-aware devices

Some network devices include a SIP ALG (Application Layer Gateway) feature that can interfere with call signalling and audio. Disable SIP ALG or SIP Helper on your router or firewall.

Look for settings labelled Enable SIP, SIP ALG, or SIP Helper and disable them.

SIP ALG can cause call issues

SIP ALG may cause registration failures, dropped calls, or one-way audio. Disabling this feature is recommended for VoIP traffic.


net2phone Canada Sync domains

The net2phone Canada apps and device provisioning services use web applications over HTTP and HTTPS. Allow outbound access to the following domains and IP addresses.

Domain IP Address Protocols
app.net2phone.com 66.22.18.191 TCP 80 / 443
auth.net2phone.com 66.22.18.212 TCP 80 / 443
prov.net2phone.com 66.22.18.221 TCP 80 / 443
p.net2phone.com 66.22.18.217 TCP 80 / 443
y.net2phone.com 66.22.18.227 TCP 80 / 443
g.net2phone.com 66.22.24.102 TCP 80 / 443

Phone provisioning services

Allow outbound access to the following provisioning services so supported devices can download their configurations during setup and registration.

Domain whitelisting is preferred

If your router or firewall supports domain-based allowlists, whitelist the vendor domains where possible. If domain-based allowlisting is not supported, use the resolved IP addresses instead.

If your router or firewall supports domain-based allowlists, whitelist the vendor domains where possible. If domain-based allowlisting is not supported, use the resolved IP addresses instead.

Click the device service type to reveal resolved IP addresses.

Bandwidth requirements

Each concurrent phone call uses approximately 88 Kbps in both directions. If two internal extensions are communicating, bandwidth usage doubles.


Quality of Service (QoS) and DiffServ prioritization

To help ensure optimal voice quality, prioritize traffic marked with EF (Expedited Forwarding) using the following values.

Setting Value
EF DiffServ Decimal 184
EF DiffServ Hexadecimal 0xb8
EF DSCP Decimal 46
EF DSCP Hexadecimal 0x2e

Many third-party networks choose not to honour these markings. However, net2phone Canada equipment does add them to real-time packets.


Cisco device configuration

On Cisco devices, disable the SIP helper using the following commands:

router(config)#no ip nat service sip tcp port 5060
router(config)#no ip nat service sip udp port 5060
