Telephone Lines

Telephone Lines></p> <p>You may require a certain type or mix of telephone lines depending on requirements as follows;</p> <p><em><u>Analogue Lines</u>:</em> required in most cases for standard Broadband connection including Fibre Broadband, albeit Broadband can only be connected to a single analogue line on a single number and not multiple line groups. Also used for standard telephony purposes including connection to telephone systems as either single or multi-line groups (2 or more lines on the same number). </p> <p><em><u>ISDN Lines</u>:</em> digital phone lines used for telephone systems which can be connected in two forms as ISDN 2 lines which come in pairs of channels (2 lines per circuit) or ISDN 30 which requires a minimum of 8 channels connected and generally works out more cost effective for larger installations.</p> <p><u>Additional facilities provided by ISDN over analogue lines are</u>:</p> <p>1. Direct Dialling In (DDI) numbers which are connected in blocks of 10 consecutive numbers can share the channels with legacy numbers and enable calls to bypass Reception phones and ring direct to individuals desks or departments.</p> <p>2. External Transfer facility enables a call to be transferred from the office back out to any external number such as mobile or home numbers etc.</p> <p>3. Log-in/Log-out Hunt Groups can be set up to control how many incoming calls can get through before the next caller gets either a Courtesy Waiting message, Voicemail or busy-tone, enabling you to control incoming call traffic during busy periods and/or when Staff levels are low or high rather than calls remaining unanswered. </p> <p><img src=
SIP Trunks: are VoIP circuits over Broadband and these can work out substantially more cost effective for larger installations and have the advantage of number portability meaning you can retain and take existing numbers to a different Exchange area if you move offices to eg a different Town. Smaller sites such as homeworkers and sites with high-speed Fibre Broadband can share Voice and Data on a single Broadband service but in most cases we would recommend using two separate Broadband services for Voice and Data with a dedicated VoIP Assured Circuit for the SIP Trunks.
