While configuring E1 PRI on ISR 4321 router I am getting below error.
VGW001(config-controller)#pri-group timeslots 1-31
E1 0/1/0: No voice port or DSP resource for voice feature
E1 0/1/0: For MFT T1E1 modules, pri-group has to have DSP (PVDM4) modules installed.
E1 0/1/0: Please check if DSP module is plugged in before configuring pri-group!
E1 0/1/0: This pri-group configuration is REJECTED!
No configuration will be applied

Can we remove PVDM4 module from ISR 4000 series router motherboard and install it on NIM-2MFT-T1/E1 card to configure E1 PRI?
Can we use this PVDM4 on NIM mudule for other IP services such as transcode and conference while no other PVDM will be present on motherboard, other than on NIM-2MFT-T1/E1 module?
