gsm and isdn at 29c3

hi list, we (ccc meber and me) are trying to get a pri access line (primary rate isdn) this year. it will provide external connection for the poc (eventphone) and will also allow interconnection of gsm network with the rest of the world. it is not yet clear if we get this line, but we are working on it. the hardware and software side is already tested in our "labs". for connection between poc and gsm network (openbsc), we like to use lcr (linux-call-router via mncc interface). there are two ways to connect to eventphone, one via isdn line (or virtual isdn over ip) and another one via sip trunk. we like to use both ways for better testing. the registration process for gsm extensions is already set up by evenphone. visit https://www.eventphone.de to register your gsm extension. for syncing eventphone's database with hlr of openbsc, i can provide help. also i will provide helpdesk for gsm questions this year again. regards, andreas
