Yeah our current CM enviroment is at ver 6.x.... Budget for upgrade but thats not until next year... So I will intstall the developement pack and see if I can port a SIP client to it int he mean time...
Unfortunately all of the 3rd party SIP clients I've run across use ARM specific native code - I'm sure to provide good DSP performance - however the Cius has an Intel/x86 CPU and these clients won't work.
CME does not yet support Cius. If you have UCM 7.1(5) or 8.5(1) or higher, the Cius device pack is a pretty easy COP install...
