CCSIP Debug doesn`t show any output

Hi - I`m having a peculiar issue with Cisco 2901 running c2900-universalk9-mz.SPA.152-4.M4.bin. The CUBE is configured to register with the carrier & it fails to register. It doesn`t seem to be attempting to send the register messages ,even. When I happen to run the debug CCSIP all , I don`t see any messages at all. Below are the output extracts from the CUBE.

Router#sh sip-ua service

SIP Service is up

CCSIP Debug doesn`t show any output

Do you have logging buffer enabled?

You can use

configure terminal

logging buffered [size]

to enable the logging buffer.

By default the output from system messages and debug is sent to a logging process.

So enable debug using

term mon

debug ccsip messages

Re: CCSIP Debug doesn`t show any output

Thanks for your response. The issue had been resolved by adding the credentials under the Sip-ua config set.
