We are expanding our geo redundant inbound Voice platform. This means you will start receiving incoming calls on your CM hosted numbers from 2 new IP addresses.
In order for your platform to be ready, we hereby request you to allow traffic from these IP addresses:
Since we will be continuously expanding our services, we also advice you to already whitelist the below subnets as well. However, when we will start using individual extra IPs from these subnets, will also communicate this separately:
The current IP addresses 188.8.131.52 and 184.108.40.206 will remain operational until further notice.
The activation of the new platform is scheduled for October 7th, 2019. From then on-wards you can expect incoming calls from the new subnets.
If you have any questions or concerns please contact the CM Support desk at the address below.
