Get Openmeetings version via SOAP/REST api

[Bhushan Patil]

Hello everyone, we have integrated older version of Openmeetings with our
application. At the time of migration to OM 3.1.2, we realized that api are
changed. We want to  keep old code as well as write new code for newer APIs.
I am unable to find soap/rest api which let us know version of Openmeetings.
Any suggestions?
