Sip Trunks

What is Sip Trunk?

A SIP trunk is the modern day equivalent of a T1 trunk. Where in the past you would buy a T1 trunk from a Telcommunication provider and connect it to your legacy PBX, today you can buy a SIP trunk from an ITSP (Internet Telephony Service Provider) and connect it to your VoIP/IP PBX. SIP trunks use the SIP standard. The name ‘trunk’ comes from the telecom world and it means, more or less, a group of phone lines. Using this standard protocol, telecom service (VoIP) providers connect one or more channels to the customer’s PBX. Phone numbers and DIDs are linked to the SIP trunk. In many cases numbers can be ported to the SIP Trunk.

Are You ready For PSTN / ISDN Switch Off

The trusted old Public Switched Telephone Network (PSTN), with its Analog lines, ISDN BRI, E1 or t1 lines, are gradually being replaced by IP telephony. An increasing number of businesses are using more modern and flexible SIP Trunks. The major telecom providers are fast phasing out the old PSTN functionality, and are moving customers to IP. Many European countries have already completely phased out ISDN with countless others to follow. The majority of businesses these days are already using modern IP phone systems and SIP trunks, although some smaller business may still rely on outdated technology. Phone companies like Verizon have phased out ISDN in the U.S. and in the UK, ISDN lines have significantly decreased. In 2017 major telcos such as KPN, France Télécom, Deutsche Telekom, Telecom Italia and BT began to phase out ISDN lines, with the UK announcing that their entire ISDN infrastructure would be retired by 2025. As a result, Session Initiation Protocol (SIP) trunking has increased dramatically, with the market value expected to reach US$35.5 billion by 2030. The SIP Trunking service is usually provided by an internet service provider (ISP). Unlike a PTSN provider, the lines provided are not physical lines, but a service provided over your internet connection. The SIP Trunk Provider provides phone numbers and lines, usually at better rates than the traditional providers and with more flexibility and shorter contract durations.

Benefit of sip trunking?

Lower monthly & DID rental

The monthly fee to have a number of lines installed at your office drops significantly with SIP Trunks. And DIDs cost a lot less.

Lower call charges

There are many SIP Trunk providers and competition has driven down call charges significantly. Some SIP Trunks even come with unlimited calling and you can save on international call charges, too.

Better customer service

Provide better customer service by adding more geographical and international numbers. Quickly and easily add numbers to your SIP Trunk and terminate them on your IP PBX – you can give customers more options to dial in at a significantly lower cost, even long distance. Customers can contact you more easily and sales will increase.

Move offices and keep your number

SIP Trunks are not bound to a location, so it’s easy to move offices without having to change your stationary or inform your customers. There is no longer any need to pay to forward phone calls to the new offices.

Eliminate VoIP Gateway

]SIP Trunks will eliminate the need to buy and manage VoIP Gateways. All phone calls come in via IP. No extra conversion often means better quality too.

Leverage a modern IP PBX

Modern IP PBX / Unified Communications solutions will give customers increased productivity, mobility and boost sales. Connecting an IP PBX to SIP Trunks is much easier than via the PSTN. You can go on-premise or hosted, the choice is yours.

Flexibility

It is easy to add channels to your SIP Trunk to cope with increased calls. A simple phone call will allow you to add channels, and often this can be done immediately. Compare that to the delay in having additional lines installed and then having to upgrade your old PBX to handle more lines!

Important Infomation

Yes all prices above include VAT.

Yes in most cases but some phone numbers with certain features cannot be ported.  This include those numbers with ISDN, Feature Line, Payphones, DDI and Remote Call Forward.  Wan active will inform you by email that your number cannot be transferred.

You can transfer your phone number from your current communications supplier at any time after you subscribe to Wan active service.  The actions you perform to transfer your phone number depends on whether your services are supplied by a cable provider or non-cable provider.  Regardless, prior to the transfer, do not cancel your existing service because you will lose the phone number that you want to transfer. 

Cable Provider

When you transfer your phone number from a cable provider, such as Virgin Media, you can experience minimal disruption to your telephone service on the day that phone number is received by Wan active. Once the phone number is released by your previous supplier, your service with that supplier will be cancelled.  You will not experience any interruption to your broadband services, as the number transfer is unrelated.

Non-Cable Provider

When you transfer your number from a non-cable provider such as BT, your setup determine the steps you must follow:  

  • Primary or Only Line with ADSL or FTTC Broadband 
  • Secondary Line Without ADSL or FTTC Broadband 
  • Secondary Line with ADSL or FTTC Broadband

Primary or Only Line with ADSL or FTTC Broadband

To maintain both your broadband and Wan active service, you must keep a traditional telephone landline. This is because the industry treats a request to transfer a phone number as request to cancel both the landline and broadband service. To avoid an interruption in your services, complete the following before you request to transfer the number to Wan active:

  1. Request that your landline supplier install another telephone landline.
  2. Contact your broadband provider and ask them to the move your internet connection to the newly installed telephone landline. 
  3. Submit a request to transfer your phone number to Wan active once your new landline has been moved to your broadband internet connection.


Secondary Line Without ADSL or FTTC Broadband

You can transfer your number to Wan active without taking any other action. When the transfer is complete, the line attached to the transferred number will be cancelled.


Secondary Line with ADSL or FTTC Broadband

Once the port to Wan active is complete, the secondary landline will be cancelled with the current supplier. 

  • If you want to cancel the broadband connection, contact your broadband supplier. 
  • If you want to keep the broadband connection, request that your landline supplier install another telephone line and then contact your broadband supplier to move your internet connection to the newly installed landline.
