DNS settings for uninterrupted VoIP services

We realized that some our customers have installed the VoIP device in some countries where good quality internet is still an issue. Our investigations show  issues in Name Servers in internet service providers prohibit registration or many times time out occurs.


The easiest and uncomplicated solution is to use the same internet service provider with different name server IP addresses in the internet router. After logging in to the router change the name servers to any of the free name servers or direct IP addresses. This will resolve the registration problems.


Following are some of the common name server IPs

  • 203.2.193.67
