CDR Access via FTP - How it works

CDRs and Services files are available to our wholesale customers via our FTP platform.

  • Daily CDR files (A folder containing records of chargeable calls made the previous calendar day based on GMT)
  • Monthly CDR files (A folder containing records of chargeable calls made the previous calendar month based on GMT)
  • Monthly Service Files (A folder containing records of chargeable services consumed either in-advance or arrears)

CDR and Service files are supplied as a comma-separated values file (.csv).

Accessing the FTP Platform

File Transfer Protocol Secure — aka FTP over TLS/SSL or FTPs — is a protocol for transferring files using Secure Sockets Layer (SSL) to secure the commands and data that are being transferred between the client and the server. We only support FTP connections over TLS (FTPS).

PLEASE NOTE: You will only be able to connect for the first time after the first billing cycle has completed successfully

  1. Download an FTP client, this will allow you to connect to our FTP platform.
    If you don't have an FTP client then we recommend Filezilla which can be downloaded here and is free: https://filezilla-project.org
  2. Create a new connection and populate with the basic details as shown below. Your username, password and host can be found in the re-seller portal under Accounts.
  3. You will now have read-only access to CDRs inline with VoiceHost data-retention policy https://www.voicehost.co.uk/privacy-policy

SSH connections will be available in the future.

Compatible Router List & General Router Configuration

General Router Setup and Configuration for the usage with the VoiceHost network

General Overview: Routers are typically the source of network issues related to the implementation of both our SIP trunks and our Cloud Platform. To ensure a network remains reliable, we recommend using the Technicolor TG582n TG589vn or TG588 for small office setups (<5 phones) and the Mikrotik range of routers (RouterOS) for deployments >10 phones or office setups requiring dual-WAN capabilities.

NOTE: The TG582n may not be suitable for PBX deployment due to difficulties port-forwarding to the PBX.

Most routers do not prioritise VoIP traffic (the Technicolor routers do this properly). Further to this, some routers actively disrupt the traffic coming through them, which further inhibits the phones' abilities to correctly route VoIP traffic. In addition, without prioritization of VoIP traffic on transmission, other devices on the network which use the available bandwidth may cause a drop in call quality. The settings below should be taken as a guide to configuring 3rd party routers. However, we cannot guarantee the success of these 3rd party routers, even when configured to have the settings below. If problems persist after these changes, we advise purchasing a recommended router.

"Free" routers provided by other ISPs may be either locked down to only their internet service or still accessible by them (meaning they can see everything you use it for). It also means that they can update it at any time, thereby resetting the main settings used to process VoIP packets. It is highly recommended to change it, even if the model number is the same.

General Router and Firewall Settings:
  • Disable SIP ALG
  • Disable SPI Firewall
  • Enable SIP Transformations (specific to Sonicwall)
  • Disable Consistent NAT (Specific to Sonicwall)
  • White-list our IPv4 addresses (contact support for info)
  • Update Firmware to latest recommended version based upon hardware
  • Do NOT open port 5060 (or the RTP ports) to any internet-based traffic (i.e. WAN links) unless you are explicitly filtering on the firewall or PBX based upon the public IP addresses of the platform. This is how SIP scanners identify systems to attempt to compromise them!

Get Digital Voice Ready - PSTN Switch Off 2027

PSTN Switch Off 2027

The Great British Switch January 2027

A significant transformation is on the horizon, the planned switch-off of the Public Switched Telephone Network (PSTN), a move that will have profound implications for businesses and consumers alike. As the traditional copper-based infrastructure makes way for newer technologies, such as Voice over Internet Protocol (VoIP) telephony, it's essential to understand what this transition entails and how embracing VoIP can help you stay ahead in the digital age.
