Robocall Mitigation Proxy
The Robocall Mitigation Proxy (RM Proxy) identifies calls with U.S. calling numbers and sends them to ClearIP for robocall mitigation.
Starting September 28, 2021, unregistered international wholesale voice service providers will have their calls with U.S. calling numbers to the U.S. refused.
The RM Proxy is an optional component in the Robocall Mitigation for Non-U.S. Service Providers solution, which enables non-U.S. providers to meet the requirements necessary to have their calls accepted by U.S. service providers.
The RM Proxy performs the following functions:
- Receives SIP messages from network elements within a telecommunications network
- Maintains a secure encrypted connection with ClearIP
- Sends SIP messages using NANP calling numbers over this secure connection to ClearIP
- Receives information back from ClearIP based upon services performed
- Sends the formatted information to network elements.
In summary, the RM Proxy acts as secure message relay.
The RM Proxy works with any SIP-based telecom system.
RM Proxy installation
Create Virtual Machines (VMs) inside your private network with 4 GB of RAM and 2 cores running CentOS 7.x or Redhat 7.x.
- The VMs must have access to the internet.
- The VMs should not have public IP addresses. We recommend that you set up them up with Network Address Translation (NAT) through a firewall.
- No ports should be opened for external access.
- All connections to ClearIP from your network will be initiated through proxies running in the VMs. They will connect to ClearIP using TLS 1.2, so all traffic will be encrypted.
- The RM Proxies will accept SIP messages on all interfaces via UDP (5060), TCP (5060), and TLS 1.2 (5061).
- Only trusted devices should be able to send SIP messages to the RM Proxies. If untrusted devices exist on the same network as the RM Proxies, you must use a firewall to limit access.
- The RM Proxy starts when installed and whenever its VM is rebooted. There is no starting/stopping or further configuration required.
To install the RM Proxy on each VM, run this command:
curl https://files.transnexus.com/clearip/installRMProxy.sh | sh -s
