Key Points
It is important that you read the entirety of and understand this document. There are, however, a few key points that we need to emphasise:
NO ACCESS TO EMERGENCY SERVICES: The Software is not a replacement for your ordinary mobile or fixed line telephone. In particular, the Software does not allow you to make emergency calls to emergency services. You must make alternative communications arrangements to ensure that you can make emergency calls if needed.
CHECK RESTRICTIONS ON USE: In some countries there maybe restrictions on the use of the type of Software being offered by OTO. It is your responsibility to ensure that you are legally allowed to use the Software where you are located.

16.5 The failure by OTO to exercise, or delay in exercising, a legal right or remedy provided by these Terms or by law shall not constitute a waiver of OTO's right or remedy. If OTO waives a breach of these Terms, this shall not operate as a waiver of a subsequent breach of the Terms.
16.6You may not assign these Terms or any rights or obligations contained in them. OTO may, without prior notice, assign these Terms or any rights or obligations contained in them to any third party.
16.7 This paragraph 16, along with paragraphs, 4.2, 12 and any other provisions, which are expressed or clearly intended to survive or operate in the event of termination, shall survive termination of the Terms.
16.8 You acknowledge and agree that if OTO is unable to provide the Software, Products and/or OTO Websites as a result of a force majeure event, OTO will not be in breach of any of its obligations towards you under these Terms. A force majeure event means any event beyond the control of OTO.

17.1 Local In-Country Subscriber Numbers and Overseas DID Numbers
(a) Availability and use. Where we provide you with a local in-country subscriber number or overseas DID number(s), you agree that:
i. you do not own the number or have a right to retain that number forever;
ii. the number provided to you is subject to applicable numbering rules and regulatory practices;
iii. you will comply on an ongoing basis with any specific number allocation requirements that we make you aware of, or any reasonable instructions that OTO or OTO's partners may give to you with regard to the use of the numbers and the Products;

OTO reserves the right to change the terms related to local in=country subscriber numbers or overseas DID number(s), including without limitation to impose or amend any residency

In certain countries, a number may be made available to you by an OTO partner rather than OTO, and you may need to enter into a separate agreement with such partner. (b) Other changes to numbers. If OTO needs to withdraw or change the number that has been made available to you, OTO will use commercially reasonable endeavors to notify you by e-mail, stating the effective date of the change and where possible, your new number. If you do not wish to accept this new number, you are entitled to terminate your number.
17.2 Subscriptions
(a) Fair Usage Policy. At OTO, we want all of our customers to get the best calling plans, known as 'subscriptions', at the lowest possible price. This Fair Usage Policy ("FUP") is designed to prevent fraud and abuse of our subscriptions by a small number of users. Subject to this FUP, OTO's unlimited subscriptions allow unlimited calls to landlines in the applicable subscription countries (excluding special, premium, service and non-geographic numbers). Unlimited calls to mobiles may also be included where stated at the time of purchase. All calls will be disconnected and require a re-dial after a 2-hour duration.
OTO's subscriptions are for personal, individual, non-commercial use only, in accordance with our Terms of Use and this FUP ("Legitimate Use"). The following is a non-exhaustive list of practices that would not be considered Legitimate Use:
i. Using subscriptions for commercial purposes or commercial gain, for example telemarketing or call centre operations;
ii. Re-selling subscription minutes;
iii. Sharing subscriptions between users whether via a PBX, call centre, computer or any other means;
iv. Calling numbers (whether individually, sequentially or automatically) to generate income for yourself or others as a result of placing the call;
v. Regular calls of short duration or calls to multiple numbers in a short period of time.
Other practices may be relevant in determining Legitimate Use and OTO reserves the right to take any unlawful, prohibited, abnormal or unusual activity into account in making its determination. OTO may at its option, terminate its relationship with you, or may suspend your subscription immediately if it determines you are using your subscription contrary to this FUP or OTO's Terms of Use. Where reasonable, OTO will provide you with notice of improper usage before suspension or termination of your subscription and, if appropriate, OTO may offer you an alternative subscription.
(b) OTO reserves the right to withdraw or change the subscriptions at any time. If OTO changes the Products included in your subscription, OTO will notify you by email stating the changes and their effective date. If you do not wish to accept these changes, you are entitled to terminate your subscription, with effect from the date on which the changes are due to take effect.
17.3 SMS
Each SMS message has a limit of 160 characters. If you type a longer message it will be broken down into several SMS messages and you will be charged for each message sent. If you send SMS messages to more than one person you will be charged for each SMS sent to each recipient. If OTO cannot (for whatever reason) send your SMS, OTO will continue to try and send the message for up to 24 hours after which time the SMS charge will be refunded to your OTO Calling Credit balance automatically if delivery is unsuccessful.

Please note that information that you voluntarily make public in your account or user profile, or which you disclose on forums, discussions boards or by posting comments will be publicly available and viewable by others.

OTO may disclose personal information to respond to legal requirements, exercise our legal rights or defend against legal claims, to protect OTO's interests, fight against fraud and to enforce our policies or to protect anyone's rights, property, or safety.

In order to provide you with OTO products you have requested, OTO may sometimes, if necessary, share your personal and traffic data with OTO's group companies, carriers, partner service providers and/or agents. For example the PSTN-VoIP gateway provider, WiFi access services providers, distributors of OTO software and/or OTO products, and/or the third party banking organizations or other providers of payment, email delivery, analytical services, customer support, or hosting services.

Your personal and traffic data can only be accessed by authorized employees of OTO or its affiliates, subsidiaries or service providers who need to have access to this data in order to be able to fulfill their given duties.


OTO may from time to time ask you to provide information on your experiences which will be used to measure and improve quality. You are at no time under any obligation to provide any of such data. Any and all information which is voluntarily submitted in feedback forms on the website or any survey that you take part in is used for the purposes of reviewing this feedback and improving the OTO software, OTO products and websites.

We will respond to requests to view, correct, complete or remove your personal information within a reasonable period of time and upon verification of your identity.
OTO will use all reasonable endeavours to accommodate requests to delete personal information unless it is required to be retained by law or for lawful business purposes


OTO will retain your information for as long as is necessary to: (1) fulfill any of the Purposes (as defined in article 3 of this Privacy Policy) or (2) comply with applicable legislation, regulatory requests and relevant orders from competent courts.

Retention of Instant Messages

Your instant messaging (IM) communications-content may be stored by OTO (a) to convey and synchronise your messages and (b) to enable you to retrieve the messages and history where possible.

OTO will at all times take appropriate technical and security measures to protect your information. By using this product, you consent to the storage of your IM and voicemail communications as described above.


OTO will occasionally update this Privacy Policy to reflect changes in our software and/or products and customer feedback. When we post changes to this Privacy Policy at our website we will update the "last revised" date at the bottom of the Privacy Policy. If there are material changes to this Privacy Policy or in how we will use your personal information, we will notify you either by prominently posting a notice of such changes prior to implementing the change or by directly sending you a notification. You agree that your continued use of the OTO software or OTO products after notice shall constitute your acceptance of the Privacy Policy.
