What are the required 'to Voxmeter VoIP Call'?
Network
See below for the protocols that need to be installed and available on the network for your phones to work properly and consistently.
Laptop/PC need to be able to initiate outbound TCP, and UDP connections to a range of Voxmeter IP addresses on arbitrary ports. In most cases, the laptop/pc initiates these connections from within home network. Any allow-list-only configuration on the firewall won't work. Please be aware that these are all destination ports that the phones send traffic to. The source port for these connections can vary by ISP (Internet Service Provider) vendor, solution, etc. Any firewall determinations based on source ports are very problematic. We strongly recommend allowing all traffic to and from our IP Blocks. Here are the specifics:
- Persistent NAT connections — Our system sends NAT keep-alive every 30 seconds.
- HTTP (TCP port 80) and HTTPS (TCP port 443) for access to https://voxmeter.catglobe.com
- SIP (UDP ports 4569) — Multiple connections must be allowed over these ports.
- Use TCP port 4569
- All internally-initiated UDP connections to ports 10,000-65,500 (RTP).
- TCP on ports 1723 Only required for Interviewer who got blocked traffic on RTP (1way sound problem). Voxmeter technical team need setup VPN on Interviewer endpoint. Our automated package can setup VPN.

Most router/access point are configurable to allow specific devices on the local network work together VoIP traffic.
It rarely to block UDP ports. We find out that few special Internet routerst block UDP traffice.
Ask your Internet Service Provider supporter for help setting this up.
1. Ask them they you can't hear sound/ audio for VoIP Call
2. You can't connect to VPN tcp/1723 too.
Computer/PC
- Windows PC installed Microsip (https://www.microsip.org/downloads) or https://www.zoiper.com/en/voip-softphone/download/current. Voxmeter A/S made new automated package setup for Interviewers at https://voxmeterinterviewer.catglobe.com/setup.exe. Guide setup at here.
- MacOS installed Zoiper or Telephony from App Store
- Linux OS PC installed Zoiper.
- Optional Headset for computer desktop.
- MacBook Pro/Air can use build-in speaker / microphone
