Cs1000e 7.6 blind transfer not working

[akak247]

I have cs1000e rls 7.6 connected to asterisks using sip trunks.

I am unable to complete a blind transfer to asterisks extn,
The transfer only happens when the asterisks extn answers the calls.

Is there any trunk configuration required for blind transfer to work.

Thanks.

The same thing was happening to me until I activated this:

PLUGIN STATUS PRS/CR_NUM MPLR_NUM DESCRIPTION
