Incoming Calls Cannot Connect – Assistance Required

Support
1

Dear FlyNumber Support Team,

I am currently experiencing an issue with incoming calls to my Australian numbers.

When my friend calls either my Australian mobile number or my Melbourne landline number (both are set to forward to my Taiwan mobile number), the call does not go through. Instead, the caller only hears a message saying “the line is busy.”

Could you please advise how to resolve this issue?

Is this possibly related to a VoIP configuration problem? Previously, I was using the free version of Zoiper, but it no longer works. Do I need to activate the Cloud Phone System Panel function on my account in order to receive calls properly?

Please let me know what settings or services need to be enabled to ensure successful call forwarding and connectivity.

Thank you for your assistance.

Hi @Jansen,

It seems the phone system was removed from your account (billing related).

You can change the forwarding to VOIP - check out this link:

Or forward directly to the Taiwanese phone number - more info on that here:

Dear FlyNumber Support Team,

I hope this message finds you well.

**I am writing to request your professional assistance in upgrading my account to the Cloud Phone System (PBX). Despite my best efforts, I have consistently failed to forward calls to my iPhone using the current SIP2SIP setup.

Currently, both of my numbers are not functional on my mobile device for either incoming or outgoing calls.

One of the main technical hurdles I encountered was the complex STUN/Network configuration on the iPhone Zoiper app, which I was unable to complete successfully. Because these numbers are critical for my immediate operations, I would like to move to your native Cloud Phone System for a more seamless and reliable connection.

I would be deeply grateful if you could prioritize the following:

  1. Enable Cloud Phone System: Please activate the PBX feature for my account as soon as possible.

  2. Simplified Setup: Please help me link both numbers above to the system. My ideal goal is to have the simplest possible way to successfully make and receive calls on my iPhone using these two numbers.

  3. Long-term Partnership & Discount: Since I intend to use this as a long-term solution for multiple business lines, I would be very appreciative if you could offer any subscription discounts or bundle plans for this combined service.

Regarding the Mobile App Configuration:

I currently have the Zoiper app installed (previously configured for SIP2SIP). Since I am moving to your Cloud Phone System (PBX), please clarify the following:

  1. App Requirement: Do I need to keep the Zoiper app on my iPhone to receive calls via your PBX, or do you recommend a different app for better stability?

  2. Setup Instructions: Regardless of the app used, please provide the step-by-step instructions and necessary SIP credentials (Domain, Username, Password, and Proxy) to successfully link my iPhone to the FlyNumber PBX.

Thank you very much for your time and for the excellent service you provide. I look forward to your prompt response.**

Hi @Jansen,

Sorry to hear about your issues, and we switched you over to the phone system.

We set up an example configuration in there to help you get started. You should also have received a separate email with quick start info.

Thanks, and I’m here if you need anything.
