What Impacts VoIP Quality?
Upload / Download Internet Speeds, Jitter and Ping Testing
Upload and Download
VoIP calls require a min. upload and download internet speed of 100KBp/s per call to send and receive HD voice. We recommend adding QoS settings to ensure internet allocation to voice.
Ping Speed
Ping is the time it takes to send and receive data packets from one server or device to another. Low Ping test scores are ideal (unless you like talking over people).
VoIP Jitter
Jitter is anything that disrupts data packet latency. High Jitter can occur due to bad hardware, congestion, WiFi, or firewall. For the best VoIP experience, low Jitter is essential.
Groups
Use Groups to gather multiple Users together based on variables such as their role, department, project team, etc. Groups can be linked to multiple callflows and refined group call reports are made available.
Example
Businesses can create a Callflow that connects a number to every User in a group when called. The most common use of this feature is for sales or support teams.
Group Monitors is a permission level that allows nominated Users to view their Group’s User details such as Call History, Contacts, Voicemails and Call Recordings.
Creating a Group
Groups can be found in the people section, followed by the Groups submenu. To create a group click on the [Add Group +] button.
A. Give the Group an applicable Name and Description, then click the [Add +] button to create this User Group and you will navigate to the Edit Group section.


B. Select the [Add Users +] button, which displays the Select Users window.


- Check the boxes left of the usernames and and click the [Select] button to review additions.


4. Once you are satisfied, click [Save >] on the bottom right corner of the window to confirm.
Firewalls, ALG, UDP
Firewalls
Firewalls sit between a computer (or local network) and another network (such as the Internet), controlling the incoming and outgoing network traffic.
With a Firewall, the firewall’s rules determine which traffic is allowed through and which isn’t.
Without a firewall, you are unprotected.
A firewall’s primary security function is blocking unsolicited incoming network traffic. Because a Firewall is sitting between two networks, it can analyze all incoming and outgoing network traffic and decide what to do with it. Firewalls can be configured with multiple conditions for certain types of traffic.
Example
For security purposes, a firewall can allow server connections from a specific IP address while blocking all connection requests from elsewhere.
Firewall Settings
Please be aware that these settings are simple best SIP practices. The Blueface Support Team is not equipped to manage complex firewall queries.
Allow IP Range: 194.213.29.0/24 (Whole Subnet)
Disable SIP ALG
Set UDP Alive Timeout to 200 Seconds.
Set QoS (Quality of Service).
Should you continue to experience difficulty with your call quality, please contact a third party IT firewall.
