How to configure VPM and VCPM module of MSR30xx?
Q：When MSR30xx has both SIC VE1 and MIM VE1, how to configure main card and MIM card? Do they need configure VPM and VCPM?
A：
If you use SIC digital voice card, you must use main card VCPM, otherwise VE1/VT1 can not run well.
If you don’t configure VoIP, and VPM is not needed, otherwise, if you configured VoIP and VPM is mandatory.
