Hi, I used the checklist and got: VALID Phone Number Configuration: Verify that the phone number is correctly associated with your SIP trunk in Vapi. Use the GET /phone-number/:id endpoint to check that all details match your configuration. VALID SIP Trunk: Make sure the SIP trunk is correctly configured with the necessary IP addresses allowlisted, as specified in the Network requirements section. VALID Assistant Linking: Confirm that the number is linked to an active assistant. You can do this via the dashboard or by checking the configuration through API calls. VALID Provider Forwarding: Ensure your provider is forwarding calls to the correct SIP URI format (e.g., your-number@sip.vapi.ai). EMPTY Call Logs: Review your Vapi call logs for any errors during call routing that might provide more insight. Support of Zadarma says that it is on your side. Moreover, the note 'This number was imported from your Vonage account.' appeared, but I didn't import the number! Would you please suggest where to check? https://cdn.discordapp.com/attachments/1412191470701772861/1412191471330791517/Screen-2025-09-02_12-43-27_AM.png?ex=68b7654c&is=68b613cc&hm=18c24febf9a1f4b2d2b38f81022414b6694b22ff6b312059392839a39c565507&

Hi OleOle, For help with accessing your account and resolving login issues, please ensure the following steps: 1. **Check Credentials**: Verify that the email and password you're using are correct.

Try clearing your browser cache and cookies or using a different browser. 3. **Verify Zadarma Settings**: If the issue persists with accessing features related to Zadarma, confirm that your Zadarma SIP credentials are correctly set in Vapi by following the integration steps outlined [here](https://docs.vapi.ai/advanced/sip/zadarma). If the problem continues after these steps, the issue might be related to incorrect SIP credentials or server address. Double-check your configuration as per the integration documentation.
