The system involves ordinary telephones; voice signals are\nmodified by the gateway into digital data packets. Each packet is transported through\nIP to a subscriber located anywhere in the world. Many different packets can be\nmoved along one line at the same time, however, the quality and speed of their\ntransportation is regulated by the congestion of the channel &#8211; sometimes\ndistortions and data loss occur. Is there an option for organizing alternative,\neven better, high-speed telephony? Yes, it is a SIP communication system. <\/p>\n\n\n\n<p>SIP-telephony also provides\ntransfer of digital packets over the Internet, but the quality of this connection\nis much better; system crashes and annoying data loss does not happen here. The\nvirtual numbers involved in the SIP system do not differ from simple telephone\nnumbers. The difference is only in the method of signal delivery. SIP, which is\na text, is used to organize communication sessions, including multimedia\nconferences.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What is more beneficial for\nthe customer: configure IP-telephony or connect SIP-connection?<\/strong><\/h2>\n\n\n\n<p>Nowadays, many companies in\nthe world use inexpensive and convenient office IP-telephony.
