Please do not add inappropriate external links to Wikipedia, as you did to Business telephone system. Wikipedia is not a collection of links, nor should it be used for advertising or promotion. Inappropriate links include, but are not limited to, links to personal websites, links to websites with which you are affiliated (whether as a link in article text, or a citation in an article), and links that attract visitors to a website or promote a product. See the external links guideline and spam guideline for further explanations. Because Wikipedia uses the nofollow attribute value, its external links are disregarded by most search engines. If you feel the link should be added to the page, please discuss it on the associated talk page rather than re-adding it. Thank you. Kuru  (talk)  11:26, 7 April 2020 (UTC)

Please stop your disruptive editing. If you continue to add promotional or advertising material to Wikipedia, as you did at Voice over IP, you may be blocked from editing. Zac67 (talk) 09:57, 21 December 2021 (UTC)

You may be blocked from editing without further warning the next time you use Wikipedia for promotion or advertising, as you did at Point-to-point (telecommunications). Zac67 (talk) 09:02, 29 March 2022 (UTC)
