Number of sessions assigned to this profile hcsdsp-cis1-mn-dh.vm(config-dspfarm-profile)#maximum sessions 15 hcsdsp-cis1-mn-dh.vm(config-dspfarm-profile)#associate application SCCP hcsdsp-cis1-mn-dh.vm(config-dspfarm-profile)#no shut Exceeds the maximum number of DSP conference profiles. The profile state is down.
