Designed to be simple to implement, many customers find the integration experience to be seamless. If you’re choosing to implement NEWT on your independently managed network and not using NEWT internet or NEWT managed services, here are a few good tips:
Tips for Preparing your Site:
Check our list of open ports which should be opened on the router to allow voice traffic to pass through (provided to you upon ordering set up).
Ensure there is existing and functional cat5 or newer ethernet drops at each location where voice phones will be installed.
Ensure you have sufficient bandwidth to support your voice services. VoIP typically required 80 – 100 kbps of symmetrical bandwidth per concurrent call. Insufficient bandwidth is likely to cause issues with your NEWT call quality.
Ensure your firewalls are open to accepting voice traffic. It’s not uncommon for firewalls to block or impair voice traffic. NEWT does not know or manage your firewall settings.
Be sure that nothing in your network (i.e.. firewall or wifi device setting ) is blocking RTP ( Real-time Transport Protocol ) or SRTP ( Secure Real-time Transport Protocol ). These are protocols for delivering voice services. Blocking RTP or SRTP within the network supporting your voice services will render any VoIP solution dysfunctional.
Voice quality can be negatively impaired by data devices running on the same network:
If you’re sharing your data and voice internet connections, it’s best to have separate ethernet drops for each phone and each data device.
It’s best to not daisy chain phones from computers because computer / data traffic can impair voice quality substantially unless you ensure your network is set up to separate voice from data traffic ( computer, printers etc. ) via vlans.
Inadequate power is commonly the culprit of partially functioning phones:
Ensure you have adequate power for the phones; either power outlets with related power supplies or a POE switch running to each phone location.
Provisioning the phones:
Once the phones get an IP, they will reach out to our servers and being the provisioning process. This can take some time, and the phone(s) may reboot several times. Should you plug in a phone, and it does not register, check to see if the phone is getting an IP before calling NEWT support. You can check to see if your phones are getting IP address by :
Grandstream device – Click Circle button > Status > Network status > Check for IPv4 to find the appropriate IP address
Poly device - Click house button > Settings > Status> Network > tcp/Ip Parameters > Check for IPv4 to find the appropriate IP address
If you can confirm that the phone is getting an IP, please complete a reboot of the device ( power cycle or on the phone go to settings – reboot) before calling NEWT support at 1-877-777-7118.
