Differnece in assigning N/W VRU CUCM and CVP

Hi All - I just want to understand below logic and why we no need to assign N/W VRU for CUCM RC.

Below is the call flow.

N/W VRU is assigned in CUCM_RC

IP Phone --> CTI R.P --> ICM --> CVP

When i assign N/W VRU for CUCM RC, ICM is sending only VRU Label and we have Max DNIS length as 10 for CVP, Since its sending only 10 Digits lablel as DN CVP its treating as new call instead of CORR ID routed call and ICM expecting DN.

// CVP

Once i assigned DN in ICM for 5555555555 its started working fine and this shouln't be the case.

Later on i removed N/W VRU in CUCM_RC and ICM started sending label for CUCM along with CORR ID.

NO N/W VRU assigned to CUCM_RC

Because CUCM is not VRU, and

Because CUCM is not VRU, and that tab is useful when deciding Type of VRU(Type 10,2 etc) if peripheral is VRU.

Just have a look at screenshot taken from Config guide, it clears says assign if Peripheral is VRU.
