There is a problem with UK access number(s).
As an example Cambridge +44-1223-858-747 (Telappliant) may be taken.

Calls to the destination SIP subscriber are connected, but in 10 sec after the answer on the SIP side the call is dropped.
Analysis on the target server shows that sipbroker server (64.34.162.221) is initiating a call over TCP and not replying with ACK to 200 OK sent by target proxy server. As a result the destination provider is terminating the call.
This doesn't happen when dialing voxalot, probably because only UDP may be used there. Calls to the same destination provider through Sipbroker access number in NYC are passing well.

If somebody is going to fix that please contact me via PM and I will provide the server-side logs.
