I am doing a task that to replace the old Cisco route voice gateway ISR3900 to the new ISR4331 device and find there is some command that cannot be supported as below.
Old configuration on ISR3900:
dspfarm profile 20 transcode universal security
trustpoint VG-ca-signed
codec g729abr8
codec g729ar8
codec g711alaw
codec g711ulaw
codec g729r8
tls-version v1.2
maximum sessions 40
associate application SCCP
Once I try to copy the old configuration to the new ISR4331.
There is no [security] command after [dspfarm profile 20 transcode universal], and meanwhile, I cannot type the [trustpoint VG-ca-signed] under the mode.
I just suspect the ISR4331 is not supporting the SCCP media secure transcode? If so. Is there any mothed to secure the media transcode?
And some other commands cannot type from old ISR3900 configuration to new ISR 4K as below.
1.
policy-map COPP-DROP-UDP
class DROP-UDP
drop
On the 4K, the drop cannot be input.
2.
scheduler allocate 20000 1000
On the 4K, the command does not exist.
