Went with A&A for our SIP Trunk for our hosted on Premise FreePBX Server which works great, BT Quoted us £40 on top of our Business Internet so decided to give A&A a whirl and it's pretty good, £10 one of fee to setup Number and Trunk, £1.40 a month for Trunk / Number. Calls are pay as you go. Highly recommended.
