I have a 3300 ICP Cx Controller V8.0. As a default it has only 4 VM ports that can be used. I think i have a dual DSP card in there for a total of 4 dsp's. If i use the command Show stat DSP it shows 4 dsp's but after i programmed the system's port capacity up to 16 and try to call one of the new VM ports it tells me "out of service". Now my question is does having this extra dual dsp card require a compression licence to make use of it's resources. And another really main question is. We have an AA menu built that handles all our incoming calls for example we only have 4 VM ports and say 3 people are in there VM box checking messages and 3 calls come into the VM AA will all 3 calls get through or will 2 of them get the busy/reorder tone. Thanks much for your help.
