STIR/SHAKEN Quick Start Guide

This document will guide you to:

  • Obtain your SHAKEN certificate from Sansay STI-CA.
  • Install your SHAKEN key to start signing calls.

If you are deploying STIR/SHAKEN from the beginning please follow this guide in sequence.

After receiving approval from the STI-PA as an authorized Service Provider, you will need to create an API user as the first step to create an account with Sansay STI-CA. If your STI-PA approval is still pending and you are looking for more information on how to answer some of iconectiv questions please use this link instead. 

  1. From the iconectiv STI-PA portal, login as Service Provider and click User Management
  2.  Click Add User:
  3. Select API as the user role when you are adding the user. Please use the name of your organization@sansay-ca.com (e.g. mycompany@sansay-ca.com) in the e-mail associated with this user. This user will give Sansay access to verify your status with the PA. Note: The confirmation of this user is time sensitive (2 hours). Please proceed with this step during normal business hours (7AM to 5PM PT).

Once you have provided Sansay an API user Sansay will proceed to create your account in the Sansay STI-CA portal @ https://sti-ca.sansay.com:4000.

This portal provides tools that facilitate certificate management.  Obtaining a certificate via Sansay's CA web portal takes less than five minutes and it is done in three easy steps.

 

  1. When the account is created you Sansay will enable access to your list of authorized users. Users will receive an introductory e-mail to reset their passwords as displayed below.  We suggest that the following steps (2-6) are only completed by one user.
  2. Log into Sansay STI-CA portal by clicking on the Reset Password button or link and entering your password. A few seconds after you set your new password you will redirected to the main login page.
  3. After successfully login to the portal you will see a welcome page. From the STI-CA portal we will be completing three steps to issue your SHAKEN certificate. The steps are as described above:
    • Generate a private key per SPC code (SPC code is usually linked to your OCN).
    • Generate a certificate signature request (CSR). 
    • Create your certificate.
  4. Create private key. Browse to Keys (top navigation bar) then click on Add. Select your SPC code (previously loaded by Sansay during account setup) and give your key a memorable name. Immediately after the key is generated your browser will auto-initiate a key download. You will need this key later on.  
  5. Create CSR. Browse to CSRs and click on Add. It is important to associate the CSR with the previously generated key.  (You don't need to download the CSR).  
  6. Generate certificate. Browse to Certificates and click on Add. You will be asked for the following information:
    • Key Pair (Private Key) generated in step 4.
    • CSR generated in step 5.
    • Certificate type: Standard End Entity.
    • Lifespan: Your choice from 1 to X days. Maximum is generally 6 months.
    • Certificate Repository (STI-CR) URL. If left blank it will be auto generated.

 

The next steps are provided for customers using Sansay's NSS solution for call authentication and verification (STI-AS and STI-VS).

Your SBC or SIP proxy/feature server will be able to obtain the SHAKEN signature via REST or SIP protocols. Customers using Sansay cloud NSS can skip steps 1-2.

  1. Initial NSS setup.
  2. Signaling IP. Browse to System > Virtual IP. Click on Add.
    1. This IP address can be the same IP as the management interface or a different IP.
    2.  Define Transport Protocol. Browse to Switches > Service Ports.
      1. e.g. UDP/5060.
    3. Define Switches. Switches will be the devices querying NSS via SIP/REST (e.g. SBC, Feature Server, PBX).   
    4. Import STI key store.
      1. Private Key. This a PEM file automatically downloaded from the STI-CA portal.
      2. Signing Algorithm: Always ES256
      3. ID Header Info: https://+(your STI-CA generated URL).
      4. Service Provider Code. Your STI-PA SPC code. A key will is need per SPC.
      5. Alias: A memorable name.
      6. Passphrase: Blank (almost always).
      7. Click on the + green button to complete the key import.
      8. Lastly attach the key to the previously created switches using the pencil icon and hitting submit.
    5. Define attestation policies.  Rules are applied in the following order SbcID, OTG and ANI.
      1. If specific SbcID is defined it will take the highest priority.
      2. If specific OTG is defined (with any SbcID) it will take the highest priority.
      3. If specific ANI (with any SbcID or any OTG) it will take the highest priority.
      4. Likewise for configurations with SbcID you can use OTG and ANI. 

VSXi

The next steps are provided for customers using Sansay's VSXi SBC.

  • Create an STI-AS App Server.
    • Browse to App Servers > STI-AS and click on Add.
    • If this is your first time creating an STI-AS the configuration below will do except for replacing the IP/FQDN for your NSS, matching NSS SIP port and specifiying the egress Service Port to query NSS. 
  • Enable STI-AS on your ingress TIDs/Resources. 
  • Make sure to enable ID header pass-thru on your egress resources such as a downstream carrier.

To enable STI-VS (call verification) repeat the steps above, except:

  • Create STI-VS App Server.
  • Enable STI-VS App Server on a per Trunk ID / Resource basis.
