Powerful telecom software platform hosted in the cloud

The ClearIP platform provides a comprehensive portfolio of services to manage and protect your telecommunications network.

These services are enabled as you configure them—use what you want and apply them to groups of calls as you wish. ClearIP performs the configured services on each call in one dip for maximum efficiency and effectiveness. It only takes milliseconds.

ClearIP works well with any SIP-based telecom system using a simple integration based upon SIP messaging. Providers, trunks and subscribers are all displayed in the user interface. Custom policies can be configured at any level. Implementation is quick and easy.

ClearIP services are billed monthly based upon usage with no contract or commitment.

ClearIP retains call activities to provide deep analytical insights. Reports, charts, and maps can be generated and exported with custom grouping and filters over any time period.

Analytics can by sliced-and-diced by specific call attributes, such as:

  • Customer
  • Provider
  • Trunk
  • Subscriber
  • IP address
  • Telephone number

SIP Analytics is the fastest fraud prevention method available

ClearIP uses SIP Analytics to perform dynamic fraud analysis before call setup. It automatically learns the call traffic patterns for each individual subscriber/trunk and destination. It can detect and prevent fraud attacks in milliseconds while legitimate calls continue uninterrupted. It’s the fastest, easiest, most precise way available to detect and prevent telecom fraud.

Fraud attack response options include:

  • Automatic blocking
  • Call teardown
  • Notification by:
    • Email
    • Text message
    • Webhooks

No user intervention is required. Fraud attack blocking affects only those calls from specific victim(s) to the attack destinations. Normal calls continue processing.

The following can be blacklisted/whitelisted:

  • Calling/called number or prefix
  • Calling/called SPID/OCN
  • Calling/called location (e.g., state/province)
  • Calling/called country
  • IP address
  • User agent

Blacklists/whitelists can apply to all calls or specific customers, providers, trunks and/or subscribers.

Robocall and TDoS (Telephony Denial of Service) prevention

ClearIP prevents unwanted robocalls and TDoS attacks using a variety of methods, including:

  • On-net calls from external networks by
    • Calling SPID/OCN
    • Calling number or prefix
  • Shield database of invalid and high-risk calling numbers
  • Calling numbers with poor reputation
  • Real-time traffic analysis
  • STIR/SHAKEN caller ID authentication and verification

Suspected robocalls or TDoS attacks can be:

  • Blocked
  • Diverted to voicemail
  • Diverted to a CAPTCHA device, which prompts for human interaction
  • Sent to the called party with the caller display name modified to indicate a suspected spam call

These actions can be enabled per customer, trunk or subscriber.

Jurisdictional static and least cost routing

abstract drawing of circles in a network configuration

ClearIP provides jurisdictional static and least cost routing.

Jurisdictional static routing can be used to route incoming DID calls and outbound calls to specific termination providers.

For jurisdictional least cost routing, rate plans can easily be uploaded and provisioned in advance of the effective date using native formats.

Routes and rates can be configured by LATA, SPID/OCN, dialed number prefix, and/or dialed number.

Providers can quickly be suspended from routing for a specific LATA, SPID/OCN and/or dialed number prefix. This enables quick routing around quality of service or call completion issues.

Custom routing can be configured per customer, trunk or subscriber.

ClearIP supports the following jurisdictional routing options:

  • International
  • Domestic
  • Intrastate
  • Local, configured as either:
    • Intra-LATA
    • Intra-Rate Center


ClearIP provides comprehensive STIR/SHAKEN certificate management, authentication, verification, call validation treatment (CVT) and analytics.

Granular policy controls enable the attestation and call handling you want for any situation you can imagine. STIR/SHAKEN policies can be configured by:

  • Customer
  • Provider
  • Trunk
  • Subscriber
  • IP address
  • Telephone number or number prefix

STIR/SHAKEN and all the other ClearIP services you configure, e.g., fraud prevention, robocall prevention, routing and CNAM are performed in one dip for maximum efficiency and effectiveness.

Branded calling

Branded calling

ClearIP supports branded calling to optimize call completion and call back. Voice service providers can make branded calling available to customers who are looking for ways to increase the value they gain from their communication services.


ClearIP provides CNAM caller ID name information. This service can be enabled per DID, should you wish to offer this as an add-on service to subscribers.

As with all ClearIP services, CNAM isn’t all-or-nothing. You can enable CNAM for some calls and not others. This is helpful when dealing with multiple providers who offer CNAM at different rates.

CNAM caller ID name information


ClearIP integrates with SIP devices using standard SIP (Session Initiation Protocol) signaling. These messages can be exchanged directly or through a proxy:

  • TLS proxy provides additional encryption security.
  • Inline proxy is used by some ClearIP customers because it makes deployment easier with their telecom network equipment and software.
  • Robocall mitigation proxy identifies calls with U.S. calling numbers and sends them to ClearIP for robocall mitigation—an essential feature for non-U.S. providers sending calls with U.S. calling numbers to the U.S.

Simply create a SIP trunk pointing to ClearIP and put it at the top of your routing table. Your network will send SIP INVITEs to ClearIP as if it were a normal SIP trunk.

ClearIP will perform the services configured for the call and return a standard SIP message to the device so that it either allows, diverts or blocks the call.

The following diagrams illustrate typical configurations and call flows for integration with SIP devices for inbound, outbound, and outbound calls with routing. Depending upon your needs, your configuration may differ from these examples.

When an inbound call is checked for robocalling. ClearIP will return to the peering SBC either a:

  • SIP 302, robocalling or TDoS detected with diversion enabled. ClearIP will return the configured diversion destination, typically voicemail or a CAPTCHA device, which prompts for human interaction.
  • SIP 503, neither robocalling nor TDoS detected, allow the call. The SBC will route advance to the switch.
  • SIP 603, robocalling or TDoS detected. The SBC will block the call before it reaches the switch or called party.

When an outbound call is checked for fraud, ClearIP will return to the peering SBC either a:

  • SIP 503, no fraud detected, allow the call. The SBC will route advance to the next destination in its local routing table
  • SIP 603, fraud detected, block the call.

When an outbound call is checked for routing, ClearIP will return to the peering SBC either a:

  • SIP 302 with a list of routes in the contact header
  • SIP 603 if the call is to be blocked as a result of any other ClearIP service (e.g., fraud prevention, STIR/SHAKEN).

ClearIP SIP trunk

Configure the SIP device with a SIP trunk directed to SIP messages must be sent using either TCP to or using TLS to

The IP address for ClearIP changes for load balancing and maintenance. That’s why you should configure the trunk using its host name, not static IP address, to avoid any service disruptions when the IP address changes.

Initially, ClearIP will respond with a SIP 403 until your account has been provisioned.

Note: does not respond to either UDP or ICMP ping messages.
