I know how to configure voice gateway DSP resource for conference bridge or transcoding resource with CCM version prior to 5.x. And on IOS gateway, we can have version keyword 5.0.1 or 4.x available:
sccp ccm 10.26.18.100 identifier 1 version 5.0.1
But when configuring IOS DSP resource with version CUCM6.x, I tried to use version 5.0.1 keyword, on CUCM6.x shows status "rejected".
Does anyone know how to configure IOS DSP with CUCM6.x and registered?
