Frequently Asked Questions

Is There a Setup Fee for Nexfon?

No. Nexfon service setup is completely free of charge. The only fees charged to subscribers are for the prefix number and call concurrency capacity.

Will Nexfon Service Be Interrupted During a Power Outage?

Respina’s infrastructure is equipped with backup power systems, so power outages will not disrupt service delivery. Subscribers’ connectivity will only be interrupted if they do not have backup power at their own premises.

Can Nexfon Lines Be Used Without Respina Internet?

No. In accordance with the requirements of the Communications Regulatory Authority and security authorities, Nexfon lines can only be used when connected to the network of the service provider operator (Respina).

What Are the Prerequisites for Nexfon?

To set up the SIP Trunk service, subscribers must have basic hardware equipment such as a VoIP server or a hardware gateway, as well as the necessary knowledge to configure this equipment. In addition, connection to the Respina network through one of the dedicated Internet services, TD-LTE, or Nexfon radio connectivity is required.

How Do Payment and Line Ownership Work in Nexfon?

All wallet top-up and payment-related processes are carried out through the subscriber user panel. According to the Nexfon contract, ownership of the lines remains with the subscriber as long as the subscription fee is paid and the line remains in use.

What Is the Term of the Nexfon Contract?

The Nexfon contract is one year by default and, in accordance with its terms, is renewed automatically.

What Is the Difference Between Nexfon’s Cloud and Local Services?

In the local service model, hardware equipment is installed and set up at the subscriber’s site. In the cloud service model, however, the subscriber does not need to purchase hardware, as the required infrastructure is provided and managed by the operator (Respina).

What Is the Role of the Server in the Nexfon Service?

To use the SIP Trunk service at the customer’s site, having a server or hardware gateway is one of the main prerequisites. Based on their needs, the subscriber configures this equipment and registers Nexfon lines on it.

Can Nexfon Lines Be Relocated?

Line relocation is possible after review and coordination with the Nexfon sales and support team.

What Are Nexfon’s Rates and How Do They Differ from Other Operators?

At present, Nexfon service rates for 8-digit lines and calls to mobile operators are approximately 12% lower than the ceiling set by the Communications Regulatory Authority.

How Is Nexfon Security Ensured?

As an FCP license holder (provider of Internet and fixed-line telephony services), Respina complies with all security requirements and fully ensures the security of subscribers’ lines and information.
