Ignore the comment about needing to be from the UK for a UK number - that only applies if you want to make calls to real phones using this service.
You must logon to your account on the SipGate website to obtain your SIP account details (logon and select "My Account").
Sipgate use a very primitive proxy. Because of this call hold or call transfer is impossible. Therefore this provider is only suitable for very basic calls. For more complex call systems and business use we recommend you use a different service provider.
