In today’s telecommunications landscape, maintaining a consistent and recognizable caller identity is crucial for business outreach. A Verified Caller ID (VCID) allows you to use a phone number you already own as your outbound caller ID through a different platform without actually transferring the number's service. While this is a highly useful feature, it is fundamentally designed as a temporary solution.
Whether you are in the midst of a platform migration or require a temporary solution for outbound campaigns, understanding how VCIDs function, the verification process, and the long-term telecom regulations in effect is crucial for your business.
How to Enable a Verified Caller ID: Proof of Ownership
To protect consumers, telecom providers enforce strict ownership checks to prevent unauthorized use of phone numbers. Enabling VCIDs is possible only if Talkdesk receives a valid proof of ownership showing that the requested number explicitly belongs to your business.
Acceptable forms of proof include:
- A recent invoice or billing statement from your current carrier.
- A screenshot from your current carrier's user interface (UI) portal.
- A Customer Service Record (CSR) provided by your telecom operator.
Important: For the verification to be approved, the document must clearly display both the phone number and your company identity.
The Risks: Why VCIDs Are a Temporary Solution Globally
Please be aware that using a VCID may cease to function at any time. Regulatory bodies and individual carriers across the globe are constantly updating their defences against spoofed numbers, which can directly impact legitimate businesses using temporary VCID solutions.
Here is why relying on a VCID carries inherent deliverability risks worldwide:
- No Troubleshooting for Failed Calls: It is highly important to note that Talkdesk does not troubleshoot failed calls originating from VCIDs. Because Talkdesk does not own or host the underlying routing for these numbers, we lack the network-level visibility required to investigate delivery failures, call drops, or spam labelling by downstream carriers.
- The Global Fight Against Spoofing: To combat the massive rise in fraudulent calls, regulatory bodies globally - from the FCC in the US and the CRTC in Canada to CEPT in Europe and the Communications Alliance in Australia - are increasing their demands so that carriers block or filter unverified traffic.
- STIR/SHAKEN and Attestation Limits: In North America, the STIR/SHAKEN framework uses digital certificates to authenticate calls. Under this system, the highest trust level ("Full Attestation" or A-level) is reserved exclusively for numbers fully hosted and verified by the originating provider. Because a VCID is hosted elsewhere, calls using it generally only receive "Partial" (B-level) or "Gateway" (C-level) attestation.
- International Carrier Filtering and Firewalls: Even in countries that have not adopted STIR/SHAKEN, carriers use advanced firewall applications and network-level filters to analyze traffic. If a localized number appears on an international interconnect link without proper authentication, or if the network cannot verify the origination, it is frequently flagged.
- The Result: Spam Tags and Blocking: Because VCIDs lack the maximum trust level associated with fully hosted numbers, they run a significantly higher risk of being relabeled as "Scam Likely," "Spam Risk," or being blocked outright by receiving carriers worldwide.
Securing Your Voice Traffic: Permanent Solutions
For a more permanent, reliable, and secure setup, we highly recommend transitioning away from VCIDs to fully integrated telecom solutions. You may want to consider the following options:
1. Porting the Number to Talkdesk
Local Number Portability (LNP) allows you to transfer the full ownership and service routing of your phone number directly to Talkdesk. Once a number is fully hosted in our system, we can verify it and sign your calls with the highest level of attestation (where applicable). This provides the best possible chance for smooth call delivery worldwide.
- Important Transition Note: When your porting process is complete, any matching VCIDs in your account will be permanently removed and replaced with the actual ported numbers. All settings linked to the temporary VCID (such as Studio Flows or Queues) will not carry over, meaning you will need to reconfigure these settings for the real numbers.
2. Bring Your Own Carrier (BYOC)
If porting is not an option (for instance, if you are tied to a specific contract with your current carrier), you can utilize a Bring Your Own Carrier (BYOC) architecture. This solution allows you to integrate your existing telecom provider directly with Talkdesk via SIP trunking. Please reach out to your Account Team for additional information on BYOC.
While Verified Caller IDs serve as an excellent bridge during transitional periods, relying on them in the long term exposes your business to deliverability risks. Moving toward a permanent solution will protect your caller's reputation and ensure your customers always know it is you on the other end of the line.
