- Active internet connection
- laptop/desktop connected to the network being tested
- access to the router/firewall of the network
You can visit our router compatibility chart to see if there are any known issues or special configuration instructions for your model of router.
Ensure the readiness tests have been completed and the results are within required Parameters:
- Line Test: https://linetest.iplogin.ca/
Your results may vary but you should be looking for the number of supported calls to be higher than your requirements for the location and the ping and jitter should be "Great" or "Okay".
Router and Firewall Requirements
- SIP-ALG should be disabled.
If the location has an aggressive firewall please allow all outbound traffic for the following ports to the following addresses. Our services use DNS-SRV and have many IP’s so the least restriction possible is important.
Required Whitelist Addresses:
- *.iplogin.ca (IP's available here)
- 80, 443, 8001 (for web UI)
- 5060 (SIP)
- 5061 (SIP TLS)
- 9002 (Web Socket used for features like Web Phone and Portal Video)
- 5060 (SIP)
- 20000-27999 (RTP Media)
SIP-ALG is a protocol used in VoIP telephony Services, A lot of routers have their own SIP-ALG enabled by default that will attempt to re-write SIP packets with their own information. SIP-ALG can and usually does exist on routers/firewalls and modems or in rare cases a managed switch.
You must disable this feature for any VoIP service to operate as expected. Typical symptoms of SIP ALG being left turned on, include:
- Phones dropping registration
- Calls going straight to voicemail for no known reason
- Calls dropping after a set period of time
- Calls dropping when trying to retrieve the call from hold
- Calls dropping when being transferred
- Calls not being received (your phone doesn’t ring)
- Unable to make outbound calls
- Calls with no audio & Calls with one way audio
- Other extensions continue ringing after a call has been answered
- Call connectivity issues - a call is transferred but the person cannot hear the caller at the other end.
You can run a test for SIP-ALG here:
This test requires you to download a small utility called BCS the first time you use it. Download links are attached at the bottom of this article for your convenience.
Your result should show that the SIP-ALG Firewall = N just like in the above picture.
If the test results show that you have SIP-ALG enabled you will need to go into your router configuration and disable it in your firewall settings, then save and reboot the router. Once the router reboots log back into the routers firewall settings and confirm SIP-ALG is disabled.
