Internet Telephone Lines – SIP vs VoIP
There are two main types of digital telephone lines in the UK: ISDN2 and ISDN30 lines. While both types of ISDN (Integrated Services Digital Network) line have similar capabilities, the key difference between them is the number of channels that they can provide. ISDN2 telephone lines provide a minimum of two channels, with the option of adding further pairs of channels as required. ISDN30 lines, on the other hand, provide between eight and thirty channels per connection, but multiple connections can be used, allowing large companies to have more than 100 channels.
As discussed in our previous post, however, ISDN and PSTN telephone lines’ days are numbered. If you run a business, it could therefore be the ideal time to switch to internet based business telephone lines.
Internet Telephone Lines – SIP vs VoIP
If you’re researching internet based telephony options for your business, you’ll find that two acronyms will keep cropping up: SIP and VOIP.
SIP (Session Initiation Protocol) isn’t actually a type of telephone system: it’s a protocol used to enable data packets to be transmitted between devices via the Internet. A SIP telephony system usually consists of internet telephone lines that are attached to a traditional onsite PBX (private branch exchange) telephone system.
VoIP (Voice Over Internet Protocol) systems often use SIP trunking to transmit data, but you don’t need to have a PBX system in order to use VoIP devices. Instead, you can make calls via a remote system operated by your service provider.
Internet based telephony solutions have many advantages for businesses. They can be more cost-effective, simpler to install, and more flexible than analogue or digital versions.
