While net2phone Canada’s 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.
The net2phone Canada service uses:
These connections will be initiated by the phone and replied to by net2phone Canada’s soft-switch. We recommend allowing outbound connections on these ports to all hosts when possible, as it avoids having to reconfigure the network device when net2phone Canada’s infrastructure is modified. If a specific address is preferred, allow communication to host proxy-pri.versature.com, proxy-sec.versature.com, and proxy-ter.versature.com. For provisioning, and to access net2phone Canada’s online tools, access to websites via TCP/IP ports 80 and 443 is required.
In the default configuration, each concurrent phone call uses approximately 88 Kbps of bandwidth in each direction. When an internal extension calls another extension on the same LAN, we must account for both legs of the call, which will use twice the bandwidth. Other codecs may be configured to reduce bandwidth use; please inquire as to the options available at your site.
Some devices contain a SIP ALG or application-level gateway, and this should be disabled to avoid causing signaling or audio problems with the net2phone Canada Service. Some devices refer to this simply as a checkbox for “Enable SIP,” please disable this feature.
On Cisco devices, disable the SIP helper using commands similar to the following:
If your network can prioritize traffic using the industry-standard DiffServ packet markings, please prioritize packets with the marking EF (Expedited Forwarding).
Depending on the specific equipment, here are some values that may assist you:
Note that many third-party networks choose not to honor these markings; however, net2phone Canada’s equipment does add them to real-time packets.
