Hi
Bogdan
thanks for the prompt and quick reply
i will be using Multi Criteria
Decision Theory (MCDT) to take the handoff decision between base stations
during a call
the possible scenario might be
e.g. if the Signal strength is not good enough in an OpenBTS cell and there is
jitter above a predefined threshold value and and some other parameters
involved (measured via dedicated OpenBTS python scripts) are crossing the
threshold values then i will use (MCDT) to take the handoff decision. Remember
that the endpoints are emulated as SIP User Agents(clients) using SIP extensions
sorry in advance if i once again did not describe my problem properly
Best Regards
Bye

Hi,
First of all OpenSIPS is a sip server so it works only with SIP.
Secondly, by default opensips is SIP proxy, so it cannot do handover.
But using the Back2Back User agent module, you may be able to play with
the ongoing calls and move them between different termination points.
I can help you more if you could describe the handover scenario you need.
Regards,
Bogdan
