Hello I am planning to build a small PBX using TDM22B. We have a Siemens Hipath 3750 in operation already. When I manage to complete my PBX using TDM22B I would ofcourse like to be able to connect my Asterisks PBX with the Siemens Hipath 3750 PBX. Will there be any issues regarding my plan ? Or is there any other issues that I need to take into account vis-a-vis Siemens PBX. I have never done all this before so I would appreciate any inputs. Thanks in advance Varun
