Connection details

Configure your IP phone or X-Lite software to use the following settings:

• Use the SIP protocol (not H.323 or Cisco's proprietary SCCP)
• Use the SIP proxy/server name lvdx.com
• Use the control panel to create a SIP username and password for each of your phones. Put the usernames/passwords into the phones.
• Use the voice codec iLBC or G.729 for the best results. Both of these codecs give good sound quality and use minimum bandwidth.
• If you are behind a NAT router, then specify the STUN server address `stun.lvdx.com' and use the SIP Outbound proxy `nat.lvdx.com:5065'

How to dial

OpenTelecoms currently uses the UK dial plan.

This means you must dial numbers the way you would from a UK telephone.

The following pattern is used:

• FREE calls to other subscribers may be made by dialing their 8 digit number, which starts with an 8. To find out your own number, dial 1701
• Dial 00 to dial an international call, eg 00 1 234 567 8888 dials the US number +1 234 567 8888
• Dial 0 to dial a UK number, eg 0207 123 4567 dials the London number 20-7123 4567
• Dial 1703 to check your remaining credit
• Dialing 1703 is a free call - this is therefore a useful way to test your phone is working before making a chargeable call.

Free UK phone numbers

Our VoIP Management System allows you to obtain UK phone numbers, including London's new 0203 numbers, and point them to your SIP device or Asterisk server.

Featured phone: Linksys SPA-941

We recommend the Linksys SPA-941 for general business use. Large display, speakerphone and conferencing, strong adherance to the SIP standard, and extensive configurability make this phone ideal for private or business use.
