[Bug]: Vobiz Inbound Workflow Signature Validation Failing

[vivek-pk]

Describe the bug

I am trying to connect my inbound workflow to the Vobiz call provider, but the inbound webhook request fails due to a signature validation mismatch.

I recently updated Dograh to version 1.32.0 (latest release).

Steps to Reproduce

1. Configure Vobiz as the telephony provider
2. Connect inbound workflow webhook
3. Trigger an inbound call
4. Signature validation fails

Expected behavior

Inbound calls should be accepted and routed to the workflow successfully.
