Thanks Pierre,
I thought that this would be the case - we had an enquiry from a client that has a reasonable number of these in service on a proprietary PBX, so I had to ask the question. I have not been able to get one for testing as yet, but have tried an LIP-8002 which is from the same family of phones. It seems to be a SIP compliant phone but I have not been able to get it to register. I don't want spend too much time on this, if it is not easy to get going and unsupported we should really tell them that they are not compatible.
Regards,
Paul
