M12 Solutions has built a strong and important relationship with Tier 1 carriers such as BT, Opal and Gamma to provide fixed lines and calls at great rates. This relationship not only means we can provide a one-bill solution for our existing or new customers, but that network-service only customers can guarantee great customer service compared with dealing with the carriers themselves.

M12 Solutions can provide lines:

• BT ISDN 2 and ISDN 30 lines and channels
• BT ISDN DDIs
• BT PSTN Traditional Analogue Lines
• BT line features such as call bar, call waiting, 1571, calling line identity presentation...
• Opal LLU PSTN line (in LLU areas for much cheaper line rental)

M12 Solutions can provide calls:

• BT Wholesale - for those companies who wish to continue using BT for their lines and calls
• Opal - a Tier 1 carrier - the business division of TalkTalk
• Gamma - for great rates and SIP lines for a more cost effective gateway to the traditional telephone network, and free inter-site calls.
