| What IP blocks should I add to my router/firewall? |
 |
Please use the information below if you have a secured/restricted network and need to know the ports and/or IP Addresses to allow for our service:
NOTE: In general ports 5060-5080 should be allowed in order to properly communicate with the Callcentric servers. Users experiencing audio issues may want to check that RTP audio is not blocked by their firewall configuration:
IP addresses/Networks
- 199.87.144.0/21 (199.87.144.0 - 199.87.151.255)
- 204.11.192.0/22 (204.11.192.0 - 204.11.195.255)
If you are making changes for security purposes or are using more advanced configurations, please make sure that the ports used with your SIP UA are not blocked by your firewall rules.
