Terms of Use
Our relationship with you
These terms are written in English, in England and are subject to English Law.

“The Company” means In:Quality Limited, Registered in England No. 09459734.

“Client” means any device or application compatible with the service

“Service” means sip.audio

“User” means any person, company or organisation using the Service

Part 1 - sip.audio

sip.audio is an internet based service which allows media encoded as data to be transmitted between two compatible clients across the internet.  These terms relate to the use of this service only and do not cover the installation or provision of hardware.

Provisions of Service

These conditions form The Company’s entire contract with the user unless an additional or replacement contract exists in writing. The Company undertakes to provide the service 24 hours a day, 365 days a year.  It is however technically impracticable to provide such a service free of faults and The Company does not undertake to do so.

Matters Beyond The Company’s Reasonable Control

The Company shall not be liable for any failure caused by matters beyond that party’s reasonable control including, but not by way of limitation, Acts of God, fire, lightning, explosion, war, disorder, flood, industrial disputes (whether or not involving that party’s employees or agents), weather of exceptional severity or acts of local or central Government or other authorities or the act or omission of any person for whom that party is not responsible.

Technical Support

It is assumed that users will have a basic level of competency in professional audio connectivity. Subscription to the service does not entitle the User to any technical support in using the service.

Suspension of Service

The Company may without notice cease to provide Service or temporarily suspend Service for the repair, maintenance or improvement of infrastructure.

Internet Connection

The service relies upon use of one or more existing connections to the internet.  It is the user’s responsibility to ensure that use of the service meets the terms and conditions laid down by  any Internet Service Provider and accepts full liability for all payments for such use.

Subscription Fees

Subscription fees are to be paid in advance by Credit Card, Debit Card, Charge Card, PayPal or other means as agreed, per calendar month or year. Monthly or Annual AutoPay subscriptions require 'continuous authority' to take repeat payments for subscription renewals until such time that a subscription is cancelled by logging into sip.audio..


It is the customer's responsibility to cancel AutoPay by logging into the sip.audio website, prior to the next scheduled payment being taken. There will be no refund of such payments.

Changes to Subscription Fees

From time to time, The Company may change the advertised amounts for subscription. In the event that prices are lowered, users may cancel their existing subscription and commence a new subscription at the lower rate. In the event that prices are raised or if a user subscribed at a lower promotional rate, The Company reserves the right to update user's recurring payment profile with the higher amount.

Relay Servers

The Company operates relay servers in North America, Europe, Asia and South America, for the transcoding and relay of some connections.  As the service grows, relay servers may be added in other locations.


We may at times promote the services of The Company within the web pages at sip.audio.


The Company accepts absolutely no responsibility for any loss of programming, content or planned business activity and any subsequent financial losses as a result of failure to establish a connection using the service for any reason whatsoever.

Part 2 - Tel

'Tel' provides the facility to make voice and ISDN audio calls from sip.audio into the worldwide Public Service Telephone Network via the internet.

Emergency Services

sip.audio is not a substitute for traditional telephony services and as such, EMERGENCY CALLS CAN NOT BE MADE THROUGH THIS SERVICE.

Service Levels

Two service levels are offered: 'Tel' and 'Tel+'. 'Tel' allows calls to landlines and some mobiles in many countries, and the ability to receive incoming ISDN audio calls. 'Tel+' also allows calls to ISDN audio codecs and a wider range of countries and mobiles.
Premium numbers, satellite phones, remote areas, or otherwise prohibitively expensive destinations may not be available. Subscribing to either Tel service does not guarantee connectivity to any particular destination.

Fair Use

The Tel service is provided on a 'fair-use' basis. The basic Tel+ service allows up to five hours of outbound ISDN calls per month. This allowance can be upgraded after the initial subscription. The company reserves the right to withdraw the Tel service from an account without prior notice and at its sole discretion if the wholesale cost of calls made exceeds that paid for the service.

Call Records

The company and its partners shall maintain and retain any such information as may reasonably be required for calculation or verification including information on individual calls. The company may disclose such information to government security services only if required to do so by law or court order.

Part 3 - Legal

The user shall not use the service for any activity that is deemed illegal in either their own jurisdiction, that of any other party, or of the company (including activities deemed unlawful under a complainant’s jurisdiction). Furthermore, the user shall not allow any unauthorised user or third party access to, or use of, the service and shall take all reasonable security measures to prevent the same.

Appropriate Use

The user warrants that any material and/or communication received, transmitted, hosted or otherwise processed using the Service will not be menacing, of a junk-mail or spam-like nature, illegal, obscene, threatening, defamatory, cause annoyance, inconvenience or anxiety; discriminatory, promote illegal or unlawful activity, be otherwise actionable or in violation of any rules, regulations or laws to which the use of the Service is subject, or infringe the intellectual property rights of the company or any third party.


The user must indemnify The Company against any claims or legal proceedings arising from the user’s use or any third party’s use of the service which are brought or threatened against The Company by another person.

Social Media

We believe that social media is vital for any modern business and from time to time will mention the activities of sip.audio users on platforms such as Twitter, YouTube and Facebook.  Individuals and organisations may request anonymity from such activity in writing.

Data Protection

The Company will hold data submitted online by users on its own and third-party servers in secure data-centres and on local storage.  All reasonable measures will be taken to ensure that data is kept secure.  Data will be used purely for the purpose of administering the service or for targeted marketing where users have granted permission for such communication.

Copyright and Intellectual Property

The Company will make no claim to any content or material broadcast, produced, shared or published using the Service.

Variation of Conditions

The Company may from time to time change the wording of these terms and conditions, the latest version of which can be found at https://sip.audio/terms.php


If any provision of this Contract is held invalid, illegal or unenforceable for any reason by any court of competent jurisdiction, such provision shall be severed and the remainder of its provisions will continue in full force and effect as if this Contract had been executed with the invalid, illegal or unenforceable provision omitted.

Part 4 - Data Collection and Retention

See our privacy policy for information on what we store, why, and for how long.
