Umtrx meeting in Paris :)

Hello team, I met in Paris with Jean-Samuel last Friday. We talked among other things about handover in OpenBTS and I wanted to share some of our ideas with you. Note: this is my recollection of things, if I misreported something it's my fault. :} # Handling SIP intricacies outside of OpenBTS We both agreed that it is better/simpler to keep the complexity of SIP protocol out of OpenBTS. There are already very good platforms that can hide the intricacies of SIP from OpenBTS (FreeSwitch, Asterisk, OpenSIPS B2BUA, etc.). The alternative (implementing a complete, compliant B2BUA SIP stack inside OpenBTS) seems difficult (complete rewrite using e.g. sofia-sip) and doesn't help with time-to-market. We also both enjoy the "GSM handset looks like a SIP endpoint" analogy that is the basis of OpenBTS and would like to keep the OpenBTS GSM-to-SIP interface as transparent as possible.
